摘　　要：西沟石墨矿赋存于中—新元古界兴东群大盘道组变质岩中,以多层矿体叠加产出,构成规模较大的矿床。矿体严格受地层层位控制,固定碳品位比较稳定。赋矿岩性主要为石墨片麻岩、石墨片岩、石墨大理岩。矿体产状与地层产状一致,矿体与顶底板围岩界面较清晰。本文主要阐述了双鸭山市西沟石墨矿床地质特征、矿石的自然类型及工业类型,总结了矿床成因类型,指出了找矿标志。The Xigou graphite deposit occurs in the metamorphic rocks of the Dapandao formation of the Xingdong group of the Meso-New Proterozoic.It is superimposed and produced by multiple layers of ore bodies,forming a large-scale deposit.The ore body is strictly controlled by the stratigraphic level,and the fixed carbon grade is relatively stable.The ore-bearing lithology is mainly graphite gneiss,graphite schist,and graphite marble.The occurrence of the ore body is consistent with the occurrence of the strata,and the interface between the ore body and the surrounding rock of the roof and floor is clear.This article mainly describes the geological characteristics of the Xigou graphite deposit in Shuangyashan city,the natural type of ore and industrial type,summarizes the genetic type of the deposit and points out the signs of prospecting.
