摘要
The first independent Te deposit discovered in China occurs at northern plunging end ofDashuigou thermal dome(diapiric granite)in centrel part of Daduhe ductile shear zone.The deposit isrepresented by an assemblage of Te,Bi,Se,Au,Ag and Cu,in which Te is a main mineralizing element.The orebody occurs as vein form,oblique to Triassic metamiorphic rocks.Studies of mineralogy,fluid inclu-sion and stable isotope geochemistry suggest that Te has been concentrated during the early period ofmineralization,and mineralization fluid may be related to hydrothermal solution from granitic magma and meteoricwater is consequent upon the fluid in the late period of Au mineralization.Preliminary study suggests thatDashuigou deposit represents a type of independent mesothermal Te deposit,which is mostly related to granitichydrothermal origin.
