摘　　要：福建由于构造活动强烈,岩浆活动活跃导致地层中既有隐晶质(煤系)石墨产出,又有晶质石墨产出。在广泛收集和研究福建以往石墨调查成果的基础上,系统总结了福建地区两类石墨矿分布概况、地质特征以及成矿地质作用。福建煤系石墨为接触变质成矿,主要赋存于中二叠统童子岩组中,分布于闽西南拗陷带内。晶质石墨矿床属于区域变质(沉积变质(后期改造))型,古元古界麻源岩群大金山岩组富含石墨片岩类或变粒岩类是福建寻找晶质石墨矿床的重要标志,分布于闽北老变质岩地区。Due to strong tectonic activity and active magmatic activity in Fujian Province,both cryptocrystalline(coal-based)graphite and crystalline graphite are produced in the strata.Based on the extensive collection and study of previous graphite achievements,distribution,geological characteristics and mineralization geology of the two types of graphite ore in Fujian were systematically summarized.The coal-based graphite in Fujian Province is contact metamorphic mineralization,which mainly occurs in the Tongziyan Formation of the Middle Permian System and is distributed in the southwestern Fujian depression belt.The crystalline graphite deposit belongs to the type of regional metamorphism type.The Dajinshan Formation of the Paleoproterozoic Mayuan Group is rich in graphite schists or leptynites,which is an important symbol for Fujian Province to find crystalline graphite deposits.It is distributed in the old metamorphic rock area in the north of Fujian Province.
