摘　　要：安徽省怀宁县象山石墨矿为一沉积变质大型晶质石墨矿床。赋矿层位主要为二叠系大隆组、龙潭组和孤峰组。矿区共圈定3个石墨矿带,32个石墨矿体。本文通过对区域成矿条件、矿床地质特征、找矿标志和矿床成因的总结分析,认为董岭变质核杂岩构造体系内二叠系含碳质地层具有找矿潜力。The Xiangshan graphite deposit in Huaining County, Anhui Province is a large meta-sedimentary crystalline graphite deposit. The ore-bearing strata are mainly the Dalong, Longtan and Gufeng Formations of Permian. Three graphite ore belts and 32 graphite ore bodies are delineated in the deposit area. Based on the summary and analysis of regional metallogenic conditions, geological characteristics, prospecting clues and genesis of the deposit, it is concluded that the prospecting potential lies in the Permian carboniferous stratum in the structural system of the Dongling metamorphic core complex.
