潭玉沟银多金属矿床成矿特征及找矿方向浅析

The Mineralization Characteristics and Prospecting of the Tanyugou Silver Polymetallic Deposit

潭玉沟银多金属矿区位于马超营断裂北侧的豫西熊耳山金银矿集区。区内主要断裂为北东向的石鼻梁断裂和焦园断裂,矿区内矿化类型主要为银(铅)矿。目前已发现的含矿蚀变带大多呈近东西向和北北西向,矿区内已发现的银(铅)矿主要集中分布于石鼻梁断裂的西侧。笔者在野外工作期间发现石鼻梁断裂东边有多条构造蚀变带,地表有孔雀石化现象,石鼻梁断裂是该区主要的容矿构造和导矿构造,所以石鼻梁断裂及其东侧的构造蚀变带可作为该区下一步找矿的重点靶区。

The Tanyugou silver polymetallic deposit is located in the north of Ma Chaoying fault in western Mt.Xiong＇er gold and silver concertrating area. The main fault zones in the area are the Shibiliang fault zone and the Jiaoyuan fault zone,trending of NE. The mineralization type in the mining area is mainly silver（lead） mine. Most of the mineralized alteration zones have been found can be divided into two groups, near east-west group and NNW group, and the silver（lead） mine which have been found in the mining area are mainly distributed in the west side of the Shibiliang fault.During the field work, the author found that there are many structural alteration zones in the east of the Shibiliang fault, and the surface was found to have the malachite petrochemical phenomenon.The Shibiliang fault is the main ore-depositing structure and ore-transmitting structure in this area, Therefore,the Shibiliang falut zone and the structural alteration zones in the east of Shibiliang falut can be used as the key target for the next prospecting in this area.
