摘要
Jianglang Dome lies at the western margin of the Tibetan Plateau,which has been identified as a metamorphic core complex.It has good ore-forming physicochemical conditions and is well known in China because it contains several Cu-sulfide deposits.Zhongzui copper deposit is characterised by polyphyletic,polyphase and polygenetic features,and has very close relationship with the evolution of Jianglang metamorphic core complex.This study is focused on the structure and metallogenic conditions of the Zhongzui copper deposit from the northern portion of the Jianglang Dome.On the basis of detailed field observations,structural previous,and previous radiometric ages,we suggest that the ore-bearing rock series in Zhongzui copper deposit underwent at least six stages of deformation,which were recorded by a series of foliations,and the ore bodies are mainly controlled by Variscan ductile shear zone and major Yanshanian gravitational sliding zones.In this contribution,we studied the ore-forming process and origin of the Zhongzui copper deposit including its ore-forming source,heating source,metal mobilization,enriching process and precipitation locations,established a single metallogenetic model,and presented some prospecting locations for similar copper deposits in the Jianglang Dome.
