栗子沟金-银(铅)矿区位于豫西熊耳山金银矿集区。矿区内矿化类型有金、银(铅)两种。含矿蚀变构造带按走向大致可分为北东、北西向两组,其中以北西向为主。区内金、银(铅)矿分别集中分布于小章沟-瓦庙沟及前咀-竹园沟、猫疙瘩-黄沙洞沟及司家庄-石鼻梁。经野外地质调查和综合研究认为,区域性的石鼻梁断裂带既是矿区内导矿构造,也是容矿构造;该区地质找矿应以银矿为主攻矿种,以熊耳群许山组和鸡蛋坪组接触界面上下地段为重点区域,尤其是猫疙瘩-黄沙洞沟一带,应是下一步找银的重点靶位。该区金找矿应加强深部找矿,寻找含矿蚀变构造带在深处交汇部位。
Chestnut gold - silver (lead) mining area is located in western Xisheshan gold and silver mine area. Mine mineralization types of gold, silver (lead) two. The ore-bearing alteration tectonic belt can be roughly divided into two groups according to the direction: north east and north west, of which the northwest is the main one. The gold and silver (lead) mines in the area are mainly distributed in Xiaozhanggou - Wamenggou and Qianzui - Zhuyuan ditch, cat lump - Huangsha ditch and Sijiazhuang - stone bridge. According to field geological survey and comprehensive study, it is concluded that the regional rock nose ridge fault zone is not only the inner ore-bearing structure but also the ore-hosting structure. The geological prospecting in this area should be dominated by the silver ore. Ping Group contact interface up and down the lot for the key areas, especially the cat lumps - Huangsha ditch area, should be the next step to find the silver target. The gold prospecting in the area should strengthen the deep prospecting, looking for ore-bearing alteration tectonic belt in the intersection of the deep.
