【摘要】 <正> 石炭、二叠系的界线,一直是个争议很大的问题。现在按照世界上多数国家地层古生物工作者的意见,二者应划在Pseudoschwagerina带之底部。我国华南的船山组或马平组,目前则把Pseudoscfiwagerina带之上的Robustoschwagerina或Staffella带归入早二叠世。上述两种划分意见,界线的上、下差着一个生物化石带。若按国际划分方案,我省的太原组势必一分为二,在北部划在一套细碎屑岩和含筵石灰岩之间,南部则在含(竹蜓)石灰岩地层内部,分属晚石炭世和早二叠世;若按我国华南的划法,太原组也有一部分更多还原

【Abstract】 It is universally accepted that the boundary between the Carboniferous and Permian is drawn the base of the Pseudoschwagerina Zone. According to this viewpoint, the Taiyuan Formation may be separated into two parts, belonging to the Late Carboniferous and the Early Permian respectivly. That makes the field work inconvenient The author suggested that the Carboniferous-Permian boundary in the North China Platform should be placed between the marine-continental deposits and the pure continental sediments, that is to say, between grey to dark-grey sandy mudstone and mudstone on the top of the Taiyuan Formation and grey to light-grey sandstone on the bottom of the Shanxi Formation.更多还原
