萝北县工农村晶质石墨矿地质特征及找矿标志

    Geological characteristics and prospecting marks of crystalline graphite deposit in Gongnong Village, Luobei County

    • 摘要: 通过开展萝北县工农村石墨矿地质勘查工作,共发现3条含石墨矿段,矿体14条,赋矿层位为下元古界兴东群大盘道组,为一套碳酸盐岩建造-炭质页岩建造变质岩系地层,主要岩性为含石墨片岩类,其次为变粒岩类、斜长角闪岩、透辉石墨大理岩、石英岩,以及少量混合花岗岩,矿体主要受地层岩性控制,矿床成因属沉积变质矿床。

       

      Abstract: Through the geological exploration of the graphite deposit in Gongnong Village, Luobei County, a total of 3 graphite bearing ore sections and 14 ore bodies have been delineated. Through the study of the geological characteristics of the deposit, it is found that the graphite ore bodies occur in the Dapandao Formation of the Xingdong Group of the Lower Proterozoic. The Dapandao Formation of the Xingdong Group of the Lower Proterozoic is a set of Carbonate rock formation carbon shale formation metamorphic rock series strata, with the main lithology of graphite bearing schist, followed by granulite, amphibolite, diopside graphite marble, quartzite and a small amount of migmatite. The ore body is mainly controlled by stratum lithology. The ore genesis belongs to sedimentary metamorphic deposit.
