摘　　要：运用煤岩学和地球化学方法 ,对中国山西浑源等 4个典型的菌藻类煤进行了综合研究 ,结果表明 ,菌藻类煤在物理、化学组成和特性上与腐植煤有明显的区别 ;其形成环境主要受 p H、Eh值和有机质含量的制约 ,其中皮拉藻和轮奇藻具有含量高、生存时间长的特征 ;The study area covers 4 mines producing sclerotia algal type coal in Hunyuan,Shanxi Province.the study combined both coal petrologic and geochemical methods indicated that the sclerotia algal coal is physically and chemically different from humic coal apparently,the forming environment is mainly controlled by pH,Eh and organic content,in which Pila Alginite and Reinschia Alginite are highly dominated.Based on the study results the genetic classification is put forward.
