Shadong tungsten deposit is situated in Hami city of Xinjiang. In the region, geological structure is complex. The 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 sheltie bed. It is provided foundation and criteria on finding this type of deposit in the area, and has very significant prospecting significance.
