东昆仑山若羌地区白干湖钨锡矿床地质特征及成因

白干湖钨锡矿床是吉林省地质调查院近年在新疆东昆仑山进行地质调查、找矿方面取得的一项重大突破。矿床产于华南、华北两大板块的增生带中,矿体赋存于古元古界金水口群地层内,属石英脉型钨矿,目前初步控制的远景规模可望达到大型以上。该矿床的发现不仅对新疆东昆仑钨锡的地质找矿具有指导意义,而且对促进南疆今后矿业经济的发展将起重要作用。

Geological features and origin of the Baigan Lake W-Sn deposit in the Ruoqiang area, East Kunlun Mountains, China.

The discovery of the Baigan Lake W-Sn deposit in the East Kunlun Mountains, Xinjiang, is an important breakthrough in geological surveys and mineral prospecting in the East Kunlun Mountains, Xinjiang, carried out by the Jilin Institute of Geological Survey in recent years. The deposit lies in an accretionary zone between the South China and North China blocks. The deposit occurs in the Paleoproterozoic Jinshuikou Group and is a quartz vein type tungsten deposit. According to its present preliminary controlled perspective ore magnitude, the deposit is expected to be classified as a large-sized deposit. The discovery of the deposit not only is conducive to guiding W-Sn exploration in the East Kunlun Mountains, Xinjiang, but also plays an important roe in promoting the development of the mining industry in southern Xinjiang.
