新疆伊宁县塔乌尔别克金矿地质特征及找矿标志

Geological Characteristics and Prospecting Signs of Tawu'erbieke Deposit in Yining County of Xinjiang Uygur Autonomous Region

摘要:

塔乌尔别克金矿赋存于下石炭统大哈拉军山组一套酸性—中酸性火山碎屑岩—熔岩建造中，矿体产出严格受断裂构造控制。矿体呈脉状、透镜状，倾角50°~70°。矿石以蚀变破碎安山岩型、斑岩型、含金隐爆角砾岩型和含金石英（方解石）脉型为主。成因与古火山机构、次火山岩有密切关系。一定的层位、断裂交会处、隐爆角砾岩及典型的蚀变为主要找矿标志。

Abstract:

Tawu'erbieke gold deposit occurred in a series of acid-medium acid volcanic fragemental rocks-lava construction in Dahalajunshan group in the lower Carboniferous period. The output of ore bodies are strictly controlled by faults. Ore bodies are vein type and lenticular type with the inclination angle of 50°~70°. Ore bodies are mainly composed of altered andesite-type, porphyry, and crypto-explosive breccia type gold-bearing quartz (calcite) vein types. Its origin has close relation with ancient volcanic agencies and sub-volcanic rocks. Certain layers, the intersection parts of faults, crypto-explosive breccia rocks and alteration are main and typical signs of ore prospecting.
