新疆巴里坤县某铜矿地质特征及找矿标志

Geological characteristics and prospecting indicators of a copper deposit in Balikun County, Xinjiang

区域大地构造位于天山兴蒙造山系(Ⅰ级构造单元)之准噶尔弧盆系(Ⅱ级构造单元)的谢米斯台—库兰卡兹干古生代复合岛弧带(Ⅲ级构造单元)内,成矿带属于双峰山-伊吾Au-Hg-Cu-Fe-矿带(Ⅳ-4-⑧)中西部。成矿条件极为有利。矿体产于石炭纪石英二长闪长岩中,构造控矿特征明显。文章结合区域成矿地质背景,通过对矿区地质特征,矿石特征及围岩蚀变特征进行综合分析,总结找矿标志,为后期该地区找寻同类型矿指明方向。

The regional geodetic structure is located in the Xemistai-Kulankazgan Paleozoic composite island arc zone(III-level tectonic unit)of the Junggar Arc Basin(Class II tectonic unit)of the Tianshan Xingmeng orogenic system(I-level tectonic unit).Inside,the metallogenic belt belongs to the central and western parts of the Shuangfengshan-Yiu-Hu-Cu-Fe-mineral belt(IV-4-8).The ore-forming conditions are extremely advantageous.The ore body is produced in the Carboniferous quartz diorite diorite,and its structural ore-control characteristics are obvious.Based on the regional metallogenic geological background,this paper comprehensively analyzes the geological characteristics,ore characteristics and surrounding rock alteration characteristics of the mining area,and summarizes the prospecting marks,which indicates the direction of the same type of mine in the later stage.
