陕西煎茶岭金矿床地质特征及其成因意义

煎茶岭金矿床产于超基性岩体与白云岩接触带的断裂构造中 ,含矿蚀变类型、矿石矿物组份以及微量元素均与超基性岩密切相关。含金矿化蚀变带的定位、矿体空间变化以及贫、富矿段的部位同时又受到多阶段活动剪切断裂控制。成矿物源主要来源于超基性岩中 ,是一处较典型的与超基性岩有关的构造蚀变岩型金矿床。

GEOLOGICAL FEATURES AND GENESIS OF GOLD ORE DEPOSIT IN JIANCHALING, SHANXI

Gold deposit of Jianchaling is located in a fracture of contact zone between ultrabasic rocks and dolomites. It has been found that the alteration type of ore containing, mineral compositions of ore rocks and microelements are of close relationship with ultrabasic rocks, and that the location of alteration belt of Au containing, change of orebody in space and location of enriched mineral rocks or poor rocks are controlled by fractures of multi stage development in the same time. Mineral materials are mainly from the ultrabasic rocks. Therefore, it is a typical gold deposit of structural alteration features, which is related to the ultrabasic rocks.
