摘要

在长白山地区和龙第二林场铁矿地质调查的基础上,结合钻探及物化探资料,发现区内存在金银矿,空间上与铁矿共生。铁矿为磁铁石英岩型,产于太古代斜长角闪片麻岩和斜长角闪岩中,属于沉积变质型铁矿床; 金银矿为含金石英脉型,产于侵入到老变质岩中的酸性岩脉中,属浅成热液型金银矿床。二者属于两期不同成矿物质的空间叠置,发育成为特有的铁、金、银多金属矿产类型。工业品位矿体主要见于北西向韧性剪切带与太古代变质岩体交汇部位,尤其是沿矿体走向 (北西向) 和切割矿体走向 (北东向) 两组断裂交汇部位。沿西拉木伦河缝合带,在韧性剪切变形较强的老变质岩区,寻找北西—北东断裂和岩脉发育带,是该类铁--金--银多金属矿床的主要找矿方向。

Abstract:

Based on the geological survey of the Helong second forest farm iron deposit in Changbai Mountain area,the authors found gold and silver ore from iron ore,which symbiosis with iron ore in the space combined with drilling and geophysical and geochemical data. Iron ore is magnetite quartzite type,hosted in Archean amphibolite gneiss and amphibolite,belonging to sedimentary metamorphic iron ore deposit. Gold and silver ore is of gold-bear- ing quartz vein type,found in acid dike invaded in the old metamorphic rocks,belonging to epithermal type gold deposit. The two kinds of deposits belong to the spatial intersection by two phase and different ore-forming materi- als,and develop into an unique iron-gold-silver polymetallic mineral type. Industrial ore body mainly appeared in the intersection part between NW-trending ductile shear zone and Archean metamorphic rocks,especially the inter- section part between two fractures,following the orebody trend (NW) and cutting orebody trend (NE). Along with the Xar Moron River suture belt,searching for NW and NE fractures and dike rocks development belt in the old metamorphic rock area which has stronger ductile shear deformation,is the main prospecting direction for this kind of iron-gold-silver polymetallic deposits.
