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��
