摘要
本文应用多重地层划分理论,比较系统地讨论和澄清了乌当地区岩石地层划分,生物地层划分和年代地层划分方面有争议的几个地层问题,提出了一些新的认识和看法,并指出生物地层研究在乌当地区还很薄弱,亟待加强。
Applying modern stratigraphic principles to discussing the stratigraphic problems at Wudang of Guiyang,this paper has clarified several deputed stratigraphic problems and added some new ideas to the stratigraphic division at Wudang from iithostratigaphy,biostratigraphy and chronostratigraphy.This paper also points out that it is imper- ative to strengthen the biostratigraphic research at Wudang.
