甘肃金塔玉山钨矿矿床成因浅析

Genesis of Yushan Tungsten Deposit in Jinta,Gansu Province

玉山钨矿主要赋存于石炭系干泉组火山岩段大理岩中,矿体受与区域构造关系密切的构造控制,呈透镜状、似层状、细脉～树枝状、脉状左斜列式形态产出,与围岩呈渐变关系。玉山钨矿床属于中低温热液型白钨矿矿床。

Yushan tungsten deposit occurs mainly in marble of the volcanic rock section of Ganquan Formation of Carboniferous. The ore body is controlled by the structure closely related to regional structure, and occurs in lenticular, layered, veinlet-dendritic and vein-like left oblique formations. It is gradually related to the surrounding rock. Yushan tungsten deposit belongs to medium-low temperature hydrothermal scheelite deposit.
