Ore-controlling Factors and Prospecting Criteria in the Xiabate Gold Deposit,Xinjiang

The Xiabate gold deposit is located in the east of the Anqi metallogenic zone,west-Junggar.The tectonic activity is intensive in this area.The regional fracture of the Hatu,Anqi and daerbote spread from north to south,and it forms the NE and NEE tectonic systems.The stratum(Tailegular Formation) is mainly the marine clastic rock and rubble rock in Carboniferous.The basalt and tuffaceous sandstone is the higher gold abundance position,and also the source of ore-forming material position.There are many magmatic rocks distributed in wide area.And the gold deposit is enveloped by the magmatic rocks of Tiechanggou,Hatu and Akebastao,etc.The Xiabate gold deposit belongs to the crushing alteration bearing gold quartz vein type.All sorts of structure controlled the distribution of the gold deposit.In the meantime the gold deposit is occurred at the position of higher gold abundance and correlated closely to the activity of magma.By the study of ore-forming features,the ore genesis of the stratum controlling and tectonics controlling are expatiated in the paper,and designate that the prospecting criteria are the gold quartz vein which lied in the structure and in the alteration zone of pyritization,ferritization,siliconizing and arsenopyrite.All these are served for the mineral resources exploration and the ore-forming prognosis.
