摘要
大东南岔西区金矿区位于三道沟-小西南岔北东向断裂带和大东南岔-杨金沟东西向断裂带交汇部,区内已发现14条金矿(化)体,分布在英云闪长岩与地层接触部的外带附近。与矿体关系最密切的矿化为褐铁矿化、硅化。矿体受近南北向次级断裂构造控制,矿体倾斜延深方向是成矿的有利部位。
The west region of Dadongnancha gold mining area is located at the intersection of the Sandaogou Xiaoxinancha northeast trending fault zone and the Dadongnancha Yangjingou eastwest trending fault zone.Fourteen gold ore(mineralized)bodies have been discovered in the area,distributed near the outer zone of the contact between the tonalite and the stratum.The mineralization most closely related to the ore body is limonitization and silicification.The ore body is controlled by the near northsouth secondary fault structure,and the dipping and extending direction of the ore body is a favorable location for mineralization.
