新疆若羌县卡尔恰尔-库木达坂一带稀有稀土、钨多金属矿地质特征及找矿方向

Rare Earth and Tungsten Polymetallic Deposits in Karchard Kumdaban Area, Ruoqiang County, Xinjiang Geological Characteristics and Prospecting Direction

研究区地处青藏高原北缘阿尔金-昆仑山构造接合带上,经历了多期强烈的造山运动,海陆变迁频繁,成矿地质条件十分优越。本文通过收集分析已有地、物、化、遥成果资料的基础上,利用矿产地质调查等方法,初步了解研究区的地质特征,大致查明该区有构造蚀变岩型贵金属矿、矽卡岩型钨矿、花岗伟晶岩型稀有稀土矿及交代型脉状萤石矿的矿床、矿体、矿石特征,为进一步探求资源量做准备。

The study area is located in the Altyn-Kunlun tectonic junction zone on the northern margin of the Qinghai-Tibet Plateau, which has experienced multiple periods of intense orogeny, frequent sea-land changes, and favorable metallogenic geological conditions. In this paper, based on the collection and analysis of the existing geological, physical, chemical and remote results, the geological characteristics of the study area are initially understood by means of mineral geological survey and other methods, and the characteristics of the deposit, ore body and ore in this area are roughly identified, including tectonically altered rock-type precious metal ore, skarn type tungsten ore, granite-pegmatite type rare earth ore and metasomatism type vein fluorite ore, to prepare for further exploration of resources.
