青海省格尔木市藏金沟金矿地质特征及成矿远景分析

Geological characteristics and metallogenic prospect of gold-gully gold deposits in Geermu Tibetan,Qinghai Province

藏金沟地区位于东昆仑南坡俯冲碰撞杂岩带(KSPZ)与东昆南缝合带(JAS)两个一级构造单元相接触的部位,主体位于东昆仑南坡俯冲碰撞杂岩带(KSPZ),地层分区属于巴颜喀拉山地层,主要为三叠系下统巴颜喀拉群昌马河组板岩与砂岩互层段,区内次级构造发育,北西向断裂在区内是主构造,也是区内主控矿构造,区内地物化等特征显示,区内具有寻找破碎蚀变岩型金矿的潜力。

The hidden gold east kunlun area south slope subduction collision complex （KSPZ） and east Queensland south suture zone （JAS） two first-order tectonic units in contact parts, main body of east kunlun south slope subduction collision complex （KSPZ）, formation belongs to balyanlkalla mountain layer partition, mainly for the Triassic series balyanlkalla group of chang landmark group under the SLATE and sandstone interval, secondary structure development of the zone, fracture in north west area is the main structure, also is the main ore structures, mainland area, according to the physical and chemical characteristics, such as area has the potential to find shattered altered rock type gold deposit.
