摘要
集安晶质石墨矿产于古元古界集安群荒岔沟组变质岩系中,矿体严格受地层层位控制,矿石质量好且易选。集安群在通化一集安一带广泛发育,为一套含石墨的火山一沉积建造,是晶质石墨矿找矿的重点区域。
Ji＇an crystalline graphite deposit originates in the metamorphic rocks of Huangchagou Formation of Paleoproterozoic Ji＇an Group, the orebodies are strictly controlled by stratigraphic horizon, and ore have good quality and easy to dressing. Ji＇an Group is widely developed in Tonghua-Ji＇an area, a set of graphitiferous volcano-sedimentary formation, which are the key prospecting area of crystalline graphite deposit.
