摘要
巴勒格坦矿区位于青海省德令哈市,2013年以来在此开展了较为详细的野外地质工作,通过地表地质调查、钻探和化学分析等系列工作,对该地区的地层、构造、岩浆岩等有了较为基础的了解,同时对该矿区铁矿矿床地质特征进行了系统的研究和分析,共圈定铁矿体20个,最大长度612m,最大延伸355m。研究表明,该矿区铁矿属小型低品位矿床,属深水湖相还原条件下沉积型菱铁矿床[4,5],具有赋矿岩性单一、顺层发育、品位低、连续性差等特点。
From 2013 to 2015,our institute has carried out more detailed field geological work.Through the work of surface geological survey,drilling and chemical analysis,we have a more basic basis for the strata,tectonics,magmatic rocks and so on.Under the same time,the geological characteristics of the iron ore deposit in the Balegetan mine area are systematically studied.The iron ore bodies we Circled are 20,of which the maximum length is 612m and the maximum extension is 355m.The study shows that the Balegetan iron ore is characterized by small and low-grade deposit,It is characterized by single metallogenic formation,bedding development,low grade and poor continuity and so on.The sedimentary siderite deposits developed in the condition of deepwater lake facies reduction[4,5].
