摘要
新疆哈密市沙东钨矿床位于中天山地块,阿拉塔格-尖山子大断裂北侧,产于蓟县系卡瓦布拉克群的一套碳酸盐建造中.区内地质构造复杂,岩浆岩发育,非常有利于钨矿富集.通过对区内地质特征研究、矿体特征和控矿因素及矿物共生组合特征综合分析,认为该矿床成因类型具多期、多成因的特点,属构造、地层控矿与岩浆热液复合成因白钨矿床.该钨矿床的发现与勘查打破了中天山一直未能找到大型钨矿床局面,为在该区寻找该类型矿床提供依据与找矿标志.
ShaDong tungsten deposit is situated in Hami city of Xinjiang ,and is located in middle -tianshan Block, North side of the Alatage-Jianshanzhi large fracture,and outputed KaWaBuLaKe group of Jixian- series of carbonate construction. In the region,geological structure is complexed ,development of magmatic rock is beneficial for tungsten ore preconcentration. Based on the regional study of geological characteristics and comprehensive analysis of orebody characteristics , ore-controlling factors and mineral Association features, there is a discussion on the genesis of the deposit ,it is believed that the origin of the genetic type of ore deposit has several more features, it＇s an ore-controlling structure, formation and origin of magmatic hydrothermal composite scheelite bed. The discovery and exploration of tungsten deposits have been Broken the situation of tinting large scale tungsten deposit in middle-tianshan Block, it is also provided foundation and criteria on finding this type of deposit in the area ,and has very significant prospecting significance.
