太原西山煤田山西组2煤层和太原组8煤层含黄铁矿煤核。在煤核中有菌藻类和植物化石。高等植物化石是种子蕨、石松类等;菌类为各种球状的真菌、杆菌、放线菌、子囊菌、菌丝;藻类有胶刺藻属、胶绿藻属、集领藻属、颗石藻、漂浮藻属、多管藻属、松藻属、团藻属、蓝球藻属、新那藻属、鱼鳞藻属、皮壳藻属、金光藻属、菱形藻属、带形藻属等。它们的形态丰富多彩,而且结构清楚。从菌藻类具有淡水、半成水和浅海环境的属种,说明在成煤过程中有海水的侵入。它们以固着、浮游和底栖的生活方式分布在泥炭沼泽中。菌藻煤核的发现,对研究成煤物质、成煤环境和菌藻生物,具有一定的地质意义。
Coal Seam 2 in Shanxi Formation of Taiyuan Xishan Coalfield and Pyrites in Coal Seam 8 of Taiyuan Formation. There are bacteria in the coal algae and plant fossils. Higher plant fossils are seed ferns, Lycopodium, etc .; fungi for a variety of spherical fungi, bacilli, actinomycetes, ascomycetes, mycelium; Algae, algae, algae, algae, cyanobacteria, cyanobacteria, genus Cyanophyta, genus Nepalensis, And so on. They are colorful and well-structured. From bacteria and algae with fresh water, semi-water and shallow sea environment genus, indicating the seawater intrusion into the process. They are distributed in peat swamps in fixed, planktonic and benthic ways. The discovery of bacteria and algae coal nucleus has certain geological significance for studying coal-forming material, coal-forming environment and bacteria algae.
