哈密沙东钨矿地质特征及成矿远景

Geological Characteristicsd and Preliminary Origin of ShaDong Tungsten Deposit in Hami

沙东钨矿位于中天山地块，阿拉塔格-尖山子大断裂北侧，产于蓟县系卡瓦布拉克群一套碳酸盐建造中。区内地质构造复杂，华力西中酸性岩浆岩发育，非常有利于钨矿富集。通过对区内地质特征及矿体特征、控矿因素和矿物共生组合特征的综合分析，对该矿床成因进行了探讨。在该矿床现有勘查成果基础上，剖析了矿床钨矿化富集规律，进一步明确了沙东地区白钨矿床的成矿远景。

ShaDong tungsten deposit is located in middle -tianshan block in hami, xinjiang.North side of the Alatage- Jianshanzhi large fracture, and is 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. Through the comprehensive analysis of regional geological characteristics, ore body characteristics, ore-controlling fac- tors and mineral association features, discussed on the genesis of the deposit,on prospecting results, analysis of the regu- larity of mineralization and enrichment of the deposit tungsten, further defined the scheelite deposit in east area of pros- pecting.
