芝坊滑石矿床地质特征及成因探讨

Geological Characters and Its Cause of Zhifnag Tale Ore Deposit

芝坊滑石矿床产于元古界粉子山群变质岩中 ,矿体呈脉状 ,受断裂构造控制 ,矿床的形成与燕山期花岗岩关系密切。

Zhifang tale ore deposite is existed in metamorphic rock in proterozoic era fenzi mountains,its orebody is as vein and it is controlled by fracture structure.The forming of ore deposit has in close relationship with granite of Yanshan period.This paper puts forward the recognition to cause of medium low temperature thermal liquid ore deposit after the magma period.
