摘　　要：吉林省集安地区晶质石墨矿床主要赋存于集安群荒岔沟组(Pt1h)含石墨岩系中,该岩性段在该区域内广泛分布。本文通过对该区域内已发现的晶质石墨矿床特征、矿体形态、产状、规模、赋存状态,以及矿石质量等进行研究分析。该区域晶质石墨矿床严格受层位控制,并受褶皱构造影响较大,矿体多为似层状、扁豆状,矿体大致平行产出,产状与地层基本一致。研究区成矿地质背景良好,成矿地质条件优越,找矿前景十分广阔。如在该区继续开展勘查工作,会取得较好的探矿效果,有望进一步扩大该区石墨资源储量。The crystalline graphite deposit in Ji’an area of Jilin Province are mainly hosted bearing rock series of Huangchagou Formation(Pt1h) of Ji’an Group, which is widely distributed in this area. In this paper, the characteristics, ore body morphology, occurrence, scale, occurrence state and ore quality of crystalline graphite deposits found in this area are studied and analyzed. The crystalline graphite deposits in this area are strictly controlled by horizon, and are greatly affected by the fold structure. The ore bodies are mostly stratoid and lenticular, and roughly produced in parallel, the occurrence is basically consistent with the formation. The research area has good metallogenic geological background, superior geological conditions and broad prospecting prospect. If the exploration work continues in this area, good exploration results will be achieved, which is expected to further expand the reserves of graphite resources in this area.
