摘要

布兰萨拉金铜矿区地处准噶尔盆地西北缘,位于萨吾尔金铜成矿带南缘。该矿床金铜成矿地质条件优越,为了查明该区金铜矿找矿前景,通过地质填图及槽探工程揭露,在区内发现金铜矿脉和矿化点32条(处),全区远景资源量金大于20 t,铜达到10 万吨以上,达到大型矿床规模。通过地质勘查前期工作,初步认为该矿床成因类型是与会聚板块俯冲岛弧带有关的构造蚀变岩型及石英脉型金铜矿床。指出了NE-NEE向断裂、花岗闪长岩—斑状二长花岗岩接触带及位于区内中东部的火山机构具有较好的找矿前景。

Abstract

Bulansala gold copper deposit,located at the northwestern margin of the Junggar Basin,the southern margin of the Sawuer gold copper metallogenic belt.It was found that gold and copper metallogenic geologic condition was relatively superior.In order to find out the gold copper prospecting prospect,we applied geological mapping and pit engineering for exploration,32 gold copper vein and mineralized points were discovered,and it was estimated that the prospective resources of gold in the whole region is more than approximately 20 tons,and copper would reach up to more than 100 thousand tons,which belongs to large scale deposit.After the preliminary geological investigation,we considered genetic types of the ore deposit indicated the close relationship with convergent plate subduction island arc belt of tectonic altered rock type and quartz vein type gold deposits.It was pointed that NE-NEE fracture structure,granite diorite-porphyritic monzonitic granite contact zone as well as the eastern central volcanic institutions in the study area had a better ore-searching prospect.
