香炉山隐伏白钨矿矿床地质特征及成因探讨

Geology and Genesis of the Xianglushan Concealed Scheelite Deposit

香炉山大型隐伏岩控角岩型白钨矿矿床,赋存在背斜构造倾伏部位的泥质灰岩与黑云母二长花岗岩的接触带上,白钨矿充填、交代钙硅角岩,定型于云英岩化阶段,矿床与燕山晚期的黑云母二长花岗岩有密切的成因关系.

The Xianlushan scheelite deposit, large in size, confined in hornfels and controlled by concealed rock formation, is located at the contact zone between and pelitic limestone over the plunge position of an anticline and the biotite monzonitic granite. The scheelite has infilled and replaced the hornfils. The deposit was settled in greisenization stage and its genesis is closely related to the Late Yanshanian biotite monzonitic granite.
