A Middle Jurassic flora consisting of 31 species of 18 genus from Zhaogou Formation in Shiguai Basin， Inner Mongolia has been studied. The flora is composed of Filicopsida，Cycadopsida，Ginkgopsid，Czekanoskiales and Coniferopsida. It is suggested that the flora belong to a late assemblage represented by Coniopteris-- Phoenicopsis in North China，aged in early Middle Jurassic.

Yixian Formation，widely exposed in Late Mesozoic basin of western Liaoning Province，is mainly a series of volcanic-sedimentary formation including some sedimentary intercalation，and bearing aboundant Jeho Biota fossils． According to research method of lithofacies paleogeography and volcanics facies，the Yixian Formation can be subdivided into 4 members，and their lithofacies are as follows: the first subcycle composed of polymictic conglomerate beds is chiefly developed in river facies． Lacustrine facies is broadly distributed in the second subcycle， formimg a set of lake sediments with rare fossils． The third one showed mainly river facies． The fourth member of Yixian Formation in mainly consists of lake facies，river facies and alluvial fan facies． They developed in small area． All of the lithologic members are composed of volcanics facies ( including volcanics subfacies) ． Through comparing with Tuchengzi age，the ancient relief of Yixian age could not be higher than the former，and paleocurrent is mainly from volcanic basin around downwarped lake． Finally，the ancient geographic environment on different sediment is restored． The study can offer important reference for regional stratigraphic correlation．

Productivity prediction of reservoirs is not only the key link of raising the exploration effect of oilfield， but also provides basic data for deployment and layout of development． Based on the theory of plane radial flow，all kinds of parameters affecting productivity have been studied． At the same time，the reservoir has been divided into several relatively homogineous subzones to predict natural productivity with full considerations of the heterogeneity． This method is used to predict natural productivity in Chaoyanggou oilfield，and the productivity grade is accords with the testing productivity grade ( coincidence rate as 100%) ． This method fits both single layer testing and multilayer testing．

A new prosauropod dinosaur Xixiposaurus suni gen. et sp. nov. from the lower Lufeng Formation of lower Jurassic in Lufeng of Yunnan, China is reported. The diagnostic characters are as follows: steep slant of the skull roof in lateral view; the maximum height of the mandible larger than twice of minimum height of the dentary; the 4th cervical centrum being longest in cervicals; minimum width of the pubic apron wider than width of the pubic peduncle; the fourth trochanter having a V-shape notch in lateral view. The phylogenetic analysis shows that it is one of the most derived forms among Chinese prosauropods.

Abstract: Hadrosauridae is taxonomically subdivided into the Hadrosaurinae and Lambeosaurinae based mainly on the skull characteristics. Hadrosaurid fossils are particularly abundant in Upper Cretaceous of Yuliangzi Formation from Longgushan of Jiayin, Heilongjiang. Mandschurosaurus amurensis (Riabinin, 1925) , the first dinosaur fossil found from China, was discovered in this locality and belongs to hadrosaurinae. Charonosaurus jiayinensis (Godefroit et al. , 2000) was also excavated here and belongs to lambeosaurinae. The authors describe a partial left dentary with dozens teeth from the Longgushan, and this new fossils clearly belong to hadrosaurinae. Because it is characterized by the following synapomorphies: 5 teeth ormore in each alveolus of the dentary and dentary marginal denticles reduced to small papillae along the dorsal half of the crown. Well developed secondary and tertiary ridges on the lingual side of the dentary crowns are unusual in hadrosaurids. The newly discovered fossil is obviously different from Charonosaurus jiayinensis occurred in the same place, while the comparisons with Mandschurosaurus amurensis are difficult, because the dentary referred to the holotype of this taxon lacks teeth in preservation.

The Sarekoubu--Tiemurte deposits in southern Altay of Xinjiang occurred in metamorphic rocks of Lower Devonian Kangbutiebao Formation． The Zn--Pb ( Cu) mineralization related to the Early Devonian marine volcanic deposition Zn--Pb ( Cu) and the late Devonian--Early carbonifeneus quartz veins mineralization related to the collisional orogeny． The former is represented by the VMS type Tiemurte Zn--Pb ( Cu) deposit，and the latter by the orogenic type Sarekoubu gold deposit，and the vein mineralization related to orogeny superposed in the VMS deposit． Based on the study and comparison of stable isotope characteristics of the two types of mineralization，combined with the deformation and metamorphism of mineralization and fluid inclusions，the authors discuss the metallogenic minerals，fluids and ore genesis． The carbonic ( CO2-CH4--N2 ) fluids inclusions are widely developed in the sulfide quartz veins of the Sarekoubu deposit and the Cu-bearing quartz veins in late stage of Tiemurte deposit，indicating that the carbonic fluid inclusions are related to the hydrothermal fluid of collision orogeny． In the Tiemurte Zn--Pb ( Cu) deposit，the δ34S values of sulfides in VMS ores range from －26. 46 × 10^-3 to － 19. 72 × 10^-3，indicating that the sulfur mainly from the inorganic reduction and bacterial reduction of seawater sulfate． The δ34S of sulfides from late superimposed veins is closed to the δ34S values of sulfides in Sarekoubu gold deposit，indicating a deep source of sulfur in the ores． The δDH2O and δ18OH2O in the Sarekoubu gold deposit and Tiemurte Zn--Pb ( Cu) deposit indicate the fluids in collision orogeny were related with the magmatic activity and metamorphism． δ13C values of CO2 in carbonic inclusions range from － 21. 15 × 10^-3 to －7. 51 × 10^-3，and those of CH4 range from －34. 11 × 10^-3 to －28. 38 × 10 ^-3 in Sarekoubu gold deposit． Whereas，δ13C values from inclusions in late Cu-bearing quartz veins in the Tiemurte range from －8. 02 × 10 ^-3 to － 6. 99 × 10^-3，δ13C show a deep source or magma source that is not related with marine volcanic sedimentary．

A new species of the Confuciusornis is described based on a specimen discovered from the Lower Cretaceous Jiufotang Formation in Toudaoyingzi of Jianchang，Liaoning Province，China. Although it is preserved with no forelimb and thoracic girdle，the new species can be distinguished from other known Confuciusornithid in many features，such as small sized，squamosal similar triangular，quadrate crassitude，anterior upper edge of dentary convex，tarsometatarsus fused proximally，metatarsals V not present，pygostyle wide and thick，etc. This discovery is the first time for Jianchang to find the taxa of Confuciusornis，and is significant for showing the diversity of Confuciusornithiformes.

Gabbro-diorite zircons from Yantongshan in central Jilin Province are euhedral-subeuhedral in shape, and display homogeneous growth zoning and high Th /U ratios (0.63～1.49) , suggesting theirmagmatic origin. LA-ICP-MS zircons U-Pb dating indicate that ²⁰⁶ Pb /²³⁸U ages of 24 spots ranging (118 ±1) to (125 ±1) Ma with a weighted mean age of (122 ±1) Ma (MSWD = 4.5) , implying the crystallization of this rock body as Early Cretaceous in age. The contents of SiO₂ are 52.41% ～53.38% , TiO₂ 1.27% ～1.95% , MgO 3.34% ～ 4.27% (Mg# = 44～47) , TFe₂O₃ 8.42%～9.48% , Na₂O 3.99%～4.31% , K₂O 1.54%～1.97%, Na₂O /K₂O 2.05～2.75 and Al₂O₃ 16.87% ～19.60%, characterizing high Na and Al. The gabbro-diorites have high light rare earth elements (LREEs) , low heavy rare earth elements (HREEs) and weakly positive Eu anomalies in chondrite- normalized rare earth element curves, and with high L ILEs (Rb, Ba and Th) and relative low HFSEs (Nb, Ta, Zr, Hf and Ti) in p rimitive mantle-normalized trace element spider diagram. The primary magma of gabbro-diorite in Yantongshan derived from the partialmelting ofmantle wedge which metasomatized by subduction fluids, and formed under an extensional environment similar to back-arc basin during the subduction of the Paleo-Pacific Plate.

LA-ICP-MS zircon U-Pb dating and geochemical data of the volcanic rocks from Mesozoic Maoershan Formation in Zhangguangcai Range were obtained for to constraining their formation time and the regional tectonic background． Zircons from two representative volcanic rocks are euhedral-subhedral in shape and display striped absorption or oscillatory zoning in CL images with high Th /U ratios ( 0. 40 ～2. 08) ，implying their magmatic origin． The dating results indicate that the volcanic rocks from Maoershan Formation were formed in the Early Jurassic ( 179 ～184 Ma) which is older than the previously believed Late Jurassic． The volcanic rocks from the Maoershan Formation display a bimodal volcanic rock association based on their petrographic and geochemical data． The trachyte and trachyandesite are characterized by high alkali ( especially K₂O) ，enrichment in large ion lithophile elements ( LILE) and light rare earth elements ( LREE) in contents，whereas the rhyolites are chemically similar to the A-type rhyolite． The bimodal volcanic rock association in Lesser Xing'an Range and Zhangguangcai Range in the studied areas implies an intense extensional environment． Combined with the spacial compositional variation ofthe Early Jurassic igneous rocks，it is suggested that the volcanic rocks from Maoershan Formation were formed under an extensional environment similar to back-arc basin which could be related to subduction of the Paleo-Pacific plate ( Izanagi) beneath the Eurasian continent．

Larap iron-copper-molybdenum deposit is formed in the island arc orogen of Luzon passive continental margin which is subducted by Philippine Plate，and located near Philippines central strike-slip fracture zone． The mineral-bearing layer is situated on tracing fracture zone of outpouring angular uncomformity between altered andesite and breccia in upper Oligocene and hornfel and hornfel shale in Paleogene． Large area of faded andesite and hornfel and zonal distributed grey-green hydrothermal fluid are metasomatized with altered rock series，the orebody is formed in such alteration zone with laminiplantation and lense shapes． Iron orebody is located in upper layer， while the copper-molybdenum ore body is located in lower layer of iron orebody together with lean magnetite． The iron orebody associates with copper and molybdenum，the copper-molybdenum body associates with iron，gold， silver，cobalt and others． Magnetite is the dominant metallic mineral in the ore，secondly are pyrite，chalcopyrite， molybdenite，pyrrhotite，uraninite，nature gold and so on． Besides iron，copper and molybdenum，other element combinations include gold，silver，cobalt and uranium． Compared with Olympic dam and Candelaria ( Chile) ironoxide copper-gold deposits，Larap deposit belongs to a new type of iron oxide copper-molybdenum-gold deposit．

Under the control of northeast-east stress field, the earthquakes in Northeast China have their special characteristics. The statistical results of earthquake space distribution and depth indicate that the earthquakes are mainly controlled by the lithospheric fault ( Kaiyuan-Chifeng fault) in Northeast China with great differences between the north and the south. The earthquakes occurred in the north are less than in the south, divided by the boundry of 44°N, and the earthquakes mainly concentrated in 4～6 km and 8～12 km in depth in the north, and in 8～12 km and 28～30 km in the south. The analysis of earthquake depth indicates that there have probably low thermal areas beneath Kaiyuan-Chifeng fault, Tanlu fault and Daxinganling fault, which provide the conditions for earthquakes getting ready in deep part. The analysis of Vp and Vs sectional data of earthquake distribution suggests that the earthquakes are often centralized in the intersectant zones of faults with velocity change zone and faultswith faults.

Western Henan located between the northern Qinling orogenic belt and the southern North China platform，is one of the important molybdenum polymetallic and precious metal metallogenic belts in China. The previous work suggested that molybdenum deposits in the area are occurred in three stages，including 233 ～ 221 Ma， 148 ～ 138 Ma and 131 ～ 112 Ma. The authors summarized the types of molybdenum deposits and their tectonic setting， types and age of magmatic rocks，and age of molybdenum deposits，and considered that the molybdenum deposits in the first stage occurred in continental extensional setting，and their formation possibly associated with its contemporary alkaline rocks. The metallogenic materials are likely originated from Dongpo Formation in Qinling orogenic belt based on the isotopes of Pb，Sr and Nd. The metallogenic elements are relatively simple，characterized by Pb or Au. The second staged deposits are possibly formed in the process of crust thickening，the remelting type and calc-alkaline rocks type I and the associated mainly with Fe and W. The third staged deposits formed in crustthinning setting，and the formation associated with potassium，high potassium or alkaline granitic rocks related to the lithosphere delamination and the upwelling of asthenosphere in eastern China. Metallogenic element is locally enriched W.

Wanbaoyuan Mo deposit in Kuandian County, L iaoning Province located in the contact region between Shizhuzi granodiorite in Yanshan stage and Cambrian carbonate formation. Mo ore bodies are divided into quartz porphyry fissure, granodioritic fissure and cataclastic alteration zone quartz vein types according to surrounding rock properties and structural location. Test results and analysis of S, O, D isotopes show that metallogenic minerals come from remelting salic crust and ore-forming fluids are mainly from magmatic watermixed with a little ancientmeteoric water. There are two stages of ore formation in this region: skarn type Cu-Fe deposits ( Ⅰstage) ; quartz vein and porphyry typesMo deposits ( Ⅱstage) , mainly is porphyry type, and both of them are the products of postmagmatic-thermal fluid.

Reverse time migration has become a standard imaging tool of complex structure such as salt model， strongly steep reflector and nappe structure，for their high precision，adapting to strong velocity variation and being free of reflector angle． The imaging condition requires the source wavefield and receiver wavefield could be obtained simultaneously，which could result in storage shortage and tremendous I /O time when large-scale data is faced． The imaging condition could also arouse low frequency artifacts in wave propagation path． Thus，a RTM scheme is proposed． To the storage and I /O problem，we use source wavefield reconstruction to ensure that the source wavefield and receiver wavefield can be available simultaneously． It means that in the forward modeling of source wavefield，we only need to store the wavefield around the imaging region and that of the last two time slices as boundary condition and initial condition of reconstruction． This strategy could decrease storage and I /O requirements greatly． We also combine up-down，left-right going wavefield decomposition imaging condition with Laplace filter to remove the artifacts of RTM． This method works well in testing． The significance of this scheme is that it could improve the method of removing artifacts in RTM，which could help to deal with the complex geological structure and give a high-quality image，and with the use of source wavefield reconstruction，it can decrease the storage and I /O time of RTM greatly．

Sandstone reservoir in the 4th Member of Xujiahe Formation in Upper Triassic of Guangpan area in Sichuan is one of the main gas reservoirs in Sichuan Province. Its reservoir rocks are fine to medium-grained lithic sandstone, feldspathic sandstone and quartz sandstone with typical low porosity and permeability. Based on the study of macroscopic depositional characteristics of the gas reservoirs in Upper Triassic Xujiahe Formation in this area, the methods with rock slides, casting thin section, scanning electronmicroscope and X ray diffraction, are used to study the diagenesis, pore evolution of gas reservoirs and the influences on storage capacity, which indicates that the sandstone in the studied area went through the diagnesis stages of compaction and p ressure solution, cementation, metasomatism, dissolution and fracturing, and then reached the B substage of middle diagenetic stage. Diagenesis is a key factor in controlling the physical property of reservoir in this area. During the process of pore evolution, the compaction and pressure solution and cementation played destructive function, while the dissolution andrim chlorite cementation played constructive function.

Liuju copper deposit is an important sandstone-type copper deposit in Chuxiong Basin of Yunnna Province. The orebody occurs chiefly in stratiform and stratiform-like structures. The sedimentary environment evolved from mendering river to oxidation-salinization lake in Late Cretaceous，and formed some favorable facies as point bar，crevasse fan and sublacustrine fan. The mineralization took place in diagenetic or buried stages. In early Yuanyongjing stage of Paleocene，while the burial depth of lower Matoushan Formation (main ore-bearing strata) as 928 m，the ore-bearing hydrothermal migrated to favorable facies，and this process may extend to late Yuanyongjing stage (56 Ma)，while the burial depth of main ore-bearing strata as 3 400 m. The reformation period may begun in Eocene，and formed some thin copper veins.

Through the measuring of 1∶50 000 stream sediments and statistical analysis of element content in original rocks, 9 synthetical abnormal places have been delineated. The abnormal places distribute mainly in Jinshuikou Group and in the contact zones of adamellite and Jinshuikou Group of Lower Proterozoic. The ore bodies distribute in the adamellite, two-mica-quartz schist and tremolite marble chiefly. W and Sn fitswell each other, the concentration centre is consistent and the concentration zoning is obviously in the synthetical abnormal places, so this region has the conditions to find hidden and semi-hidden hydrothermal metal minerals with medium-high temperature, which is the relative best position to looking for tin-tungsten ores.

A vanadium-bearing titanomagnetite deposit with low grade，shallow occurrence and large scale has been found in Alatan Gol of Xiwuqi，Inner Mongolia． The main ore-bearing intrusion is composed of gabbro and minor diorite，evjite，olivine gabbro，etc． The core petrography of drills showed that the olivine gabbro with high basic degree always occurred in the middle and low section of ore-bearing rock，whereas the diorite with low basic degree in the upper and margin section of ore-bearing intrusion． The main ore mineral includes magnetite，coulsonite， titanomagnetite，pyrite，chalcopyrite and a little amount of rutile． Among them，magnetite，coulsonite and titanomagnetite were distributed among silicate minerals in spongy aerosiderite，dissemination and scattered star shapes． The structural characteristics are typical magma liquation and crystallization differentiation，which are similar to of the Panzhihua iron deposit in Sichuan． Compared with traditional magmatic deposits，the high-grade ore body of Alatan Gol deposit currently found in the upper intrusion and there widely developed alteration in country rock． The conclusion can be drawn that the superposition of later hydrothermal played an important role to the formation and rebuilding of the present deposit．

In order to meet the requirements of data quality control in various regional geochemical surveys, including 1∶50000, 1∶200000 and multi-target geochemistry, and to improve work efficiency, the quality control system for regional geochemical sample analysis has been developed. Since the system is highly professional and adopted B/S and C/S developmentmodes, it is crucial for designing some key modules, such as the design of key database tables, download of orders, upload of analytical results, insert of quality control samples and real-time control of data quality, etc. The realization of these key modules in detail and gives the program codes of several modules is described in this paper.

The main magmatic rocks in Jinchanggou are granodiorite porphyry in category. The contents of the rocks are 62.60%～64.18% in SiO₂ , 6.57%～7.45% in Na₂O + K₂O, with K₂O > Na₂O, 4.48-6.68 in the modified calc-alkali index (MAL I) , 1.44-1.79 > 1.1 for alumina saturation index (ASI) , which shows P-riched ( > 0.2% ) and belongs to magnesian, alkalin and peraluminium granite, and having a high differentiation degree (D I = 71.71～76.92). The granodiorite porphyry formed in the tectonic setting of collision or late orogeny, and its source materials mainly sourced from the crust, and the source rock is most likely from the arenite.

Based on the detailed field survey and laboratory analysis, the authors studied lithology, sedimentary conformation and palaeontological characteristics of the sedimentary strata of Yixian Formation in northern Hebei and the sedimentary environment has been analyzed. Results indicate that Senjitu Basin in northern Hebei has experienced enormous changes of sedimentary environment and frequent replacements of lithofacies types and rock combination, showing the evolution model of rapid deposition basin-filling. The sedimentary environment divided into fluvial deposit and lacustrine deposit. The sedimentary evolution of each depositional circle usually began with alluvial channel to fluvial deposit, and evolved into lacustrine deposit which is mainly made up of shore-shallow lake sedimentary model with relatively stirring hydrodynamic condition. The volcanism also had greater impact on the depositional environment during this period.

Through the methods of polarizing microscope and cathodoluminescence, the diagenesis of Late Carboniferous phylloid algal reefs in southern Guizhou is studied, which indicates diagenesis are mainly of bio-binding and baffling actions, micritization, cementation, compaction-pressure solution, fracture, recrystallization and dissolution in type. Based on thin section analysis and cathodoluminescence, the diagenesis can be subdivided into four stages, including quasi-contemporaneous diagenesis phases, early diagenesis phase, burial diagenesis phase and epigenetic diagenesis phases. Diagenetic and cathodoluminescent characteristics show that the reefs have gone through marine, meteoric freshwater and buried diagenetic environment.

Guaishishan mafic-ultramafic complex in Beishan region of Gansu is a copper-nickel mineralized basic rocks. Their geochemical data show that theMg^# of basic rock is 74, and the Mg^# of ultrabasic rock is 84-90, which indicates the primary magma and early cumulation in characteristics. The total content of rare-earth and trace elements is low in ΣREE, the chondrite-normalized REE distribution pattern is slightly right enriched, and with 0.99-1.95 (La / Sm) _N , 1.13-2.96 (La / Yb) _N , 1.16-2.37 (Ce / Yb) _N , 0.93-1.02 (δEu) and 0.91-0.95 (δCe) in contents. Combining with the tectonic setting analysis of the rock, the authors consider that the mafic-ultramafic complex was produced in the active continental margin environment, and aged in Devonian with SHRIMP U-Pb dating. The subduction activity in Beishan area of Gansu in Paleozoic might continue to Devonian, in which the spinel peridotite in upper mantle partially melted in this process, and the rising magma was not contaminated significantly so that formed this copper-nickelmineralized mafic-ultramafic complex in Guanshishan.

Diagenetic and metallogenetic ages of Wuxing Pt-Pd deposit in Jidong of Heilongjiang Province has been uncertain for a long time. Single zircon SHRIMP U-Pb dating from mineral-bearing rock body indicates that the ages of 12 group s of experimental data are 35.8-40.3 Ma, the weighted mean age is 37.79 ±0.76 Ma. Com-bining with the characteristics of zircon CL image, the authors comfirm that the diagenetic time of Wuxing mineral-bearing rock body and the metallogenetic time of Cu-Ni and Pt-Pd are Late Eocene. Considered the formation time being consistent to the eruption event of alkali basalt magmatic in Dunmi fracture zone, it is concluded that the formation environment was related to Dunmi fracture, which shows the direction to look for Cu-Ni, Pt-Pd deposits in Northeast China.

In order to solve the problem of domestic water supply in new urban developed area of Qingshuihe County of Inner Mongolia, the authors discussed the relative hydrogeologic parameters, utilizing the investigation data on the basis of analyzing hydrogeologic conditions in water source region. The infiltration coefficient of precipitation is 0.19 and the recharge rate of river is 873.13 m³/d. Equalization method has been used to evaluate of groundwater resource, and ensure the allowable exploitation as 40 769.14 m³/d, which meets the demand ofwater requirement in future.

A set of sediments yielding abundant fossils, sandwiched in volcanic rocks, outcrop in the Linglongta area of  Jianchang County in western Liaoning Province. The fossils consist of conchostracans, ostracods, bi- valves, fish, insects, plants, vertebrates, etc. Based on the regional stratigraphic investigation, measuring geological section and synthetic study of the fossils newly collected in the Daxishan site, the authors have assured the sed- iments belonging to the Tiaojishan Formation aged in Middle Jurassic, and the formation is underlying the Yixian Formation stratigraphically. The fossil assemblage of the Tiaojishan Formation indicates the characters of the Middle Jurassic Yanliao Biota.

Through an integrated study of Mesozoic sedimentary characteristics in J iyang depression, the authors put forward a set of methods for studying sedimentary facies in reworked residual basins. The main concept including the field outcrop, core, sample log, well logging and the basinal structures.

The microstructures include bracket particles and macroporous micro-cemented structure, bracket particles and macroporous-inlay particles and microporous half-cemented structure, flocculated-cemented structure and clotted-cemented structure. The loess has preferable physical and mechanical properties: dry density is 1.15～1.76 g/cm³ , average content of natural water is 18.31% , c is 7.5～86.3 kPa, φ is 14.0～29.9 degree, etc., and the collap sible loessmainly belongs to medium-collapsibility.

The comprehensive study of geological characterisics，ore-controlling regularity and geophysical and geochemical data of Wunugetushan copper-molybdnum deposit shows the new orebody signs in deep and peripheral mining areas are: the multi-stages hypabyssal-super hypabyssal intermediate-acidic subvolcanic formed in the most intensive period of subvolcanic activity can be regarded as the key target area; and the planar altered halo having metasomatic and obvious zonation of Si⁴⁺, K⁺ and (OH) ^－ and the geochemical anomaly joined with excitation anomaly can be regarded as an important mark. Geophysical and geochemical exploration and drilling data confirm that there may exist new orebody in deep and peripheral mining area.

Through the sedimentologic analysis of Niaohe and Hongshishan sections in Niaohe village of Binxian， combined with the information of paleontology，geochemistry and paleogeography，the authors restored paleoenvironment characteristics preliminarily. In the Niaohe section，the strata mainly consist of gray-green mudstone with pyrite and dolomitic tuberculosis layers，belonging to lake bay environmental deposit. In the bottom of Hongshishan section，the strate are mainly composed gray-green mudstone，changed to red mudstone in top and middle part，belonging to shallow lake at early stage，gradually turned to mud-flat deposit. The sediments were mainly mudstone and developed horizontal bedding when the provenance was not sufficient; yielding less fossils，but the layered property was good; there were dolostone and pyrite in mudstone. The lake bay accepted deposition by water deepening from the fracture depression of lake basin，and water flow or wave erosion damaged the barrier in lake bottom and lakeshore which led to water shallowed and turned to slough finally.

The Quaternary deposits are widely distributed in western Liaoning, centered by Dalinghe River and Xiaolinghe River, where the Karst is very developed in the region geographically, mainly due to the Ordovician limestone as the bedrocks. Under the water solution, these carbonate rocks formed a lot of caves various in size, which provided ideal habitats for the mammals living during the Quaternary time. By 1970s, many sites yielding the mammal fossils were discovered in the region, such as Jianping, west Bajianfang of Lingyuan, Gezidong of Kazuo, Shenjiatai of Jinzhou. Since then, many new sites, e. g. Moershan of Kazuo, the Cave of Erchibu, Mashandong of Chaoyang, Goumendong of Lingyuan, were found one after another. According mainly to the fossil mammal assemblages and their comparisons, the fossils found from western Liaoning represent four geological stages: the late Middle Pleistocene, early Late Pleistocene, middle Late Pleistocene and late Late Pleistocene. These discoveries are very significant for the study of Quaternary mammals, and the divisions and correlation of Quaternary in western Liaoning even for whole Northeast China.

Late Triassic—Early Cretaceous granites in Jilin Province can be divided into three types tectonically originately, including cracking, strick-slip and convergent types, according to the regional tectonic evolution, rock assemblage and isotopic dating data. The cracking type suite is related to Cu, Ni, P, V and Timagnetite, the strick-slip type suite is related to the noble metallic and pollymetallic deposits, and subduction subtype granite suite of convergent type intra-plate sheet (A type) is related to the porphyry Mo, Au and Cu deposits. The deposits formed by Early Jurrasic magmatism are mainly Mo, and turned to Au, Cu and Pb-Zn deposits in Late Jurassic—Early Cretaceous. The regular update and progress of cause structure type magmatic suite reflect the interactive comp lexity between the Pacific Plate and the Northeast Asian continental margin of peri-Pacific Plate, and the evolutinary regulartion of the magmatism.

Early Cretaceous granitic volcanic-intrusive complex in Xiushanlinchang of northeastern Da Hinggan Mt. consists mainly of rhyolite, rhyolite ignimbrite-trachytic dacite, trachyandesite formed ineruptive cycle stage and adamellite porphyry-geode syenogranite-graphic alkali feldspar syenogranite formed in hypabyssal invasion stage. Later intrusive body filling in the center of collap se caldera formed by volcanic eruption, and the rocks have graphic texture and geode structure without dark alkaline minerals. The age of rhyolite (118.20 ±1.90 Ma) is similar to the intrusive rocks (116.86～118.3 Ma). Most rocks of the comp lex belong to alkaline series with high silicon, alkali, aluminum, Ga and HFSEs. The spider diagrams of trace elements of these rocks are close, with Sr, Ba low valley. The rare-earth distribution patterns are similar too, and p resent slightly LREE enrichment asymmetric right wing “seagull” type and medium Eu negative anomaly. The ⁸⁶Sr /⁸⁷Sr and ¹⁴³Nd /¹⁴⁴Nd initial values of rhyolite and quartz syenite are also similar. The time-space-source consistency indicates that the comp lex is aluminum A1-type granite and formed in non-orogenic intrap late extensional tectonic setting under the extension mechanism of lithosphere.

Based on the research in black soil in Siping area, three points with different parent material profiles were sampled. Through testing the contents of trace elements and constant elements of the samples, and analyzing the data by the means of longitudinal and transverse analyses, the results show that the contents of geochemistrical elements have great discrepancy in different parentmaterial layers. Though there are inheritance characters in the black soils in surface, the contents of soil geochemical elements have changed in the same climate and vegetations for a long time, and the geochemical characteristics of the black soils in different parent materials incline to coherence.

Wenquan porphyry molybdenum deposit of West Qinling is located in northwestern Caledonian fold belt of North Qinling. The identification of polished section and slides，X--diffraction analysis，chemical total analysis of rocks and minerals and REE analysis show that molybdenite，pyrite and chalcopyrite mineralizations in quartz vein are the main types of mineralization in the deposit; while silicification，laumontite and red argillation are the main types of wall-rock alteration. According to the characteristics of deposit geology，wall-rock alteration and geochemistry， the wall-rock alteration can be divided into three zones，including brick red zeolitization ( gradeⅠ)， strong silification (gradeⅡ) and weak silification (gradeⅢ)，in which the gradeⅠand Ⅱ zones are the main indicators for prospecting.

Jinchang gold deposit of Heilongjiang is a large rock gold deposit dominated by explosive brecciation pipe type mineralization．Taking the explosive brecciation pipe type J0 ore body as the main example，the authors discussed the geochemical characteristics of this kind of ore body through the geochemical analysis of lithological trace elements in six defferent levels． The results showed that among the twelve analyzed elements，the anomalies of Hg，As，Sb mostly occurred at the top up of gold ore bodies; the anomalies of Ag，Pb，Zn，Cu mainly occurred in the middle part of gold ore bodies; whereas the anomalies of Ni，Mo，W，Co are mostly located at the lower part or at the tail part end of the gold ore bodies． The distribution characteristics of the elements anomalies can be used as indicators for evaluating the gold-bearing features of the explosive brecciation pipes and predicition analysis of deep prospecting potential in Jinchang gold mining district．

Utilizing sides identification, scanning electron microscope ( SEM) , inclusion temperature meas2 urement and mercury penetration analysis, the authors study the petrological characteristic of reserviror, diagenesis type, diagenesis stage and model of diagenesis evolution. The rocks of the reserviror in the studied area are fine2 coarse feldspathic lithic sandstone and lithic feldspathic sandstone in type, and the sandstone experienced the diag2 nesis ofmechanical compaction and p ressolution, chemical bond, alternation, corrosion and claymineral inversion. According to the diagenesismarks, the Qingshankou Formation belongs to A2-A3 substages of late diagenesis stage. The model of diagenesis evolution indicates that during the deposit of the Members^2nd-3rd ofNenjiang Formation, the Member1 st of Qingshankou Formation is at the A1 substage of late diagenesis stage, and theMembers^2nd-3rd of Qingshankou Formation are at the B substage of early diagenesis stage and A1 substage of late diagenesis stage; during theMingshui Formation, the whole Qingshankou Formation is at the stage of A2 substage; while in Paleocene, the Member^1st of Qingshankou Formation goes into the A3 substage of the late diagenesis stage, and the middle and upper parts of the Member^2nd-3rd of the Qingshankou Formation are at the A2 substage of late diagenesis stage.
