摘要
叙述铜陵、黄山一带晚泥盆世—早石炭世五通群地层的划分和对比。据岩性、沉积构造、古生物等特征,讨论了研究区五通群的时代划分和古地理环境。五通群近顶部出现风化暴露面,表明当时存在一个沉积间断,在间断面之下为擂鼓台组,间断面之上为陈家边组,其纵、横向上的变化受古地理、古气候、古构造的控制。
This article describes the subdivision and correlation of the late Devonian and early Carbonife- rous Wutong Group in the Tongling and Huangshan areas. On the basis of lithostratigraphic characteris- tics sediment structures, sedimentary facies, and biostratigraphic data, the spatial distribution and varia- tion of the Wutong Group is discussed. A subaerial exposure surface is recognized and a sedimentary hiatus is inferred to be present in the upper Wutong Group, between the Leigutai and Chengjiabian formations. The spatial variation of this exposure surface is controlled by paleotopography, paleoclimate, and loval structures.
