湖南杨家山钨(铜)矿地质特征及深边部找矿远景

Geological characteristics of yangjiashan w (Cu) deposit in Hunan Province and its deep and marginal prospecting prospect

杨家山钨(铜)矿主要矿体发育于岩体与浅变质岩接触带附近断裂构造带中,属岩浆期后高-中温热液充填型白钨矿床,伴生铜、锡、铅、锌、金等多金属矿。本文通过对矿区地质条件及矿床地质特征的阐述,探讨了矿床成因,对矿区深边部找矿远景进行分析研究,提出杨家山钨(铜)矿以南以及北西、南东深部方向存在较好的找矿远景,有望在该矿区寻找大型-超大型的钨(铜)多金属矿床。

The yangjiashan tungsten(copper)deposit is mainly developed in the fault structural zone near the contact zone between the rock mass and the hypabyssal metamorphic rock,belonging to the post magmatic high middle temperature hydrothermal filling type scheelite deposit,accompanied by copper,tin,lead,zinc,gold and other polymetallic deposits.Based on the description of geological conditions and geological characteristics of the deposit,this paper discusses the genesis of the deposit,analyzes and studies the prospecting prospect in the deep and edge of the mining area,and points out that there are good prospecting prospects in the south of yangjiashan tungsten(copper)deposit and in the deep direction of Northwest and Southeast,which is expected to find large and super large tungsten(copper)polymetallic deposits in the mining area.
