新疆雪米斯坦火山岩带南翼铀多金属成矿控制因素分析

摘要

Uranium mineralization polymetallic main occur in continental sub-volcanic and intermediate-acidic volcanic rocks in the south of xuemisitan volcanic belt, and it is controlled in large fracture acute holding area. In order to clearly reveals further prospecting direction in the south of xuemisitan volcanic belt, On the basis of research uranium polymetal-lic mineralization related of lithology and lithofacies, tectonic alteration and mineralization characteristics, consider urani-um polymetallic ore zone obviously. At the western main prospect uranium beryllium molybdenum deposits which is con-trolled for sub-volcanic zone, at the central main prospect uranium copper deposits which is controlled for subprime frac-ture zone, at the eastern main prospect uranium molybdenum deposits which is controlled for collapse type volcano framc.%　　雪米斯坦火山岩带南翼铀多金属矿化主要赋存于陆相次火山岩、中酸性火山岩中，受控于大型断裂锐角夹持区。在研究与铀多金属成矿相关的岩性岩相、构造蚀变及矿化特征基础上，认为铀多金属矿化分带明显。西段主要寻找受次火山岩接触带控制的铀铍钼矿，中段主要寻找受次级裂隙带控制的铀铜矿，东段主要寻找受塌陷式火山机构控制的铀钼矿。
