吉林省洮南市东升乡铜矿床地质特征及成因分析

摘要

Dongshengxiang copper deposit mainly occurs in metamorphic volcano tuffaceous clasolite, tuffaceous sandstone rocks of the Paleozoic Earthem Permian system Dashizhai Formation. The geological features of the deposit and the occurrence of the ore bodies are introduced and the Genesis of deposit are analyzed, the mineralization is mainly controlled by the fracture and ifssure strctures, the genesis of the deposit must have belonged to mesothermal-epithermal. The prospecting criteria are determined, Pointed out the directions to ifnd ore in the area in the future.%东升乡铜矿主要赋存于古生界二叠系大石寨组变质的火山凝灰碎屑岩、凝灰质砂岩中。本文介绍了矿床地质特征、矿体的赋存状态并分析了矿床成因，认为矿化主要受断裂裂隙构造控制，属于中低温热液成因。确定了找矿标志，为今后在该地区找矿指明了方向。
