摘要
本文详细研究了淮北煤田早二叠世地层植物化石1300余块,其分属于10大类共69属165种。该区早二叠世植物化石丰富,保存良好,是典型的华夏植物群。根据该期植物群的纵向发育规律和空间分布特点,其可划分为两个植物组合,即早二叠世早期山西组的Cathaysiopteris whitei-Callipteridium koraiense-Cordaites schenkii组合带和早二叠世晚期下石盒子组的Lobatannularia ensifolia-Gigantonoclea spp.-Caulopteris spp.组合带。
This Paper studies carefully over 1300 specimens of LOwer Permian fossil plants in Huaibei coal field belonging to 69 genera and 165 species of 10 classes respectively. The fossil plants are abundant and in good preservation in this coal field. It is a typical cathaysiana flora. According to its vertical developing law and space distribution characteristics, it may be divided into two assemblage zones, i. e. Cathaysiopteris whitei-Callipteridium koraiense-Cordaites schenkii assemblage Zone of Shanxi Formation in early stage of Lower Permian and Lobatannularia ensifolia-Gigantonoclea spp.-Caulopteris spp.assemblage zone of Lower Shihezi Formation in later stage of Lower Permian.
