摘要
本文从煤岩学、沉积学、古生物学和地球化学等方面分析了中,梁山北矿 K_2、K_4煤层和南桐砚石台矿四号、六号煤层的煤相;根据从煤中发现的植物残体和含煤岩系中发现的大化石确定了成煤植物的类型;并根据从煤中发现的细菌化石结合地化分析阐述了泥炭沼泽的介质性质。
The coal facies of K_2,K_4 coal seams in zhong liang shan mining region and №.4,№.6 coal seams in Nan Tong mining region will be discussed in this paper from coal petrology,sedi- mentology,palaeontology and geochemistry.Especially,the coal forming plants can be defined from the plant residue discovered from coal and plant fossil from coal bearing sequence;and the medium of peat swamp can be defined from the bacteria fossil and geochemical.analysis.
