本文论述了中国南部二叠纪末、三叠纪初的沉积岩相和生物相类型,并划分了若干性质不同的沉积区和相区。晚二叠世晚期有2个沉积区和8个相区;三叠纪初则演变为2个沉积区和斗个相区。文中还探讨了古生代与中生代之交沉积环境、气候以及生物群的演替等问题,认为中国南部大部分地区二叠系与三叠系之间无论岩相或生物相都显示了过渡性质。 This paper discusses the sedimentary facies and biotectic types of the Late Permian and Early Triassic in southern China and divides several sedimentary and facies zones of different nature. Late Permian has two depositional zones and eight facies; Late Triassic evolved into two depositional areas and bucket phase area. The paper also discusses the sedimentary environment, climate and the succession of biota at the turn of the Paleozoic and Mesozoic. It is believed that the transitional facies between the Permian and Triassic rocks in most parts of southern China shows either the lithofacies or the biotransformation.
