摘　　要：中二叠统童子岩组是福建最重要的含煤层位,所赋存的煤炭资源占全省煤炭资源总量的98%,具备煤系石墨形成的物质基础。由于福建岩浆侵入期次多、范围广,多期次构造运动形成的褶皱、断裂构造发育,多因素作用下使煤进一步形成不同石墨化程度的隐晶质石墨。依据各要素对成矿作用的影响程度,对福建省煤系石墨成矿模式展开探讨,初步认为,福建省煤系石墨有以下三种成矿模式:封闭式成矿模式、半开放-半封闭式成矿模式、开放式成矿模式。The middle Permian Tongziyan Formation is the most important coal-bearing horizon in Fujian Province.Its hosted coal resource is account for 98%in total coal resource of the Fujian Province thus with material basis to form coal measures graphite.Owing to multistage and extensive igneous intrusions,as well as multistage tectogenesis formed well developed folds and faults etc multiple factors have made coal further formed into cryptocrystalline graphite with different graphitization degrees.Based on factors impact degree in ore-forming process,has discussed coal measures graphite minerogenic mode.Tentatively considered that coal measures graphite in Fujian Province has enclosed type,semi-open type and open type three minerogenic modes.
