通过青海省德令哈市哈拉湖地区镜铁矿的地质背景、成因类型的分析和研究,查明镜铁矿赋存于早石炭世臭牛沟组红色碎屑岩及石英脉中,铁矿石中矿物成分简单,金属矿物以镜铁矿、菱铁矿为主,脉石矿物以石英为主,地表呈大鳞片状分布在脉石英矿物之间,通过槽探工程揭露,深部以致密状、团块状产出,该处脆性断裂构造十分发育,矿体受后期构造热液成矿明显,具有很好的找矿指示意义.

Through analysis and research of geological background and oregenesis of specularite in Hala lake region of Del-ingha, Qinghai province, it is found that the specularite orebody is hosted in the red clastic rock and quartz vein in the Chouniugou group in the early Carboniferous epoch, with simple mineral composition in the iron deposit, mainly specular-ite, siderite for the metal minerals, and mainly quartz for gangue minerals, distributed in the surface in large scales be-tween vein quartz mineral.Pit project reveals the compact, crumb output in depth with well-developed brittle fracture struc-ture and, the ore body is influenced by later tectonic hydrothermal mineralization, with great significance in prospecting in-dicator.
