摘要
在系统研究贵州地区已有的南华系地层剖面基础上,根据其分布、发育情况,岩性、岩相及其所反映的古构造、古地理、古气候特征,将贵州的南华系分成江南地层分区和扬子地层分区,并进一步将江南地层分区划分出锦屏—榕江小区和松桃—丹寨小区。应用岩石地层和气候地层相结合的方法,对贵州各地层区的南华系进行岩石—气候地层划分,并与相邻省区及加拿大、澳大利亚地区南华系(成冰系)进行对比。同时对目前南华系划分中的一些问题进行了讨论。
A systematic study of the Nanhuan System in Guizhou Province shows that two lithostratigraph- ic regions can be recognized： the Yangtze region and Jiangnan region, based on the distribution and development of Nanhuan strata, lithofacies, palaeogeography, and paleoclimates. The Jiangnan region consists of the Jinping-Rongjiang subregion and the Songtao-Danzhai subregion. The Nanhuan System of Guizhou Province can be divided using a combination of lithostratigraphic and climatic stratigraphic tools. A stratigraphic correlation scheme has been proposed to correlate the Nanhuan System in Guizhou and Cryogenian strata in adjacent provinces, Canada, and Australia.
