江西二叠系地层分区及岩石地层单位讨论

STRATIGRAPHIC REGIONALIZATION AND LITHOSTRATIGRAPHIC UNITS OF THE PERMIAN IN JIANGXI

依据沉积特征,笔者将江西省二叠系划分为扬子区、江南区和华南区三个沉积区,并进一步划分为六个小区。地层研究证实各区间都存在过渡状态。本文还将万载小区改归扬子区,扬子区分界已越过九岭。过去江西省二叠系岩石地层名称诸多紊乱,本文分别予以讨论、清理。

On the basis of sedimentary features, the author divided the Permian in Jiangxi Province into three sedimentary regions, the Yangtze region, Jiangnan region and South China region, which are further divided into six areas. Stratigraphic studies have confirmed that there exist transitional relationships between various regions (or areas). In this paper the Wanzai area is assigned to the Yangtze region and the limits of the Yangtze region have surpassed the Jiuling Mountains. The Permian lithostratigraphic names in Jiangxi Province are too numerous and chaotic. They are discussed and elaborated in the paper.
