贵州寒武纪地层分布广泛,岩相及生物相类型纵横变化迅速,对于各时期地层岩相及生物相类型的划分、变化规律以及相应的古地理环境,笔者等已在“贵州及其邻区生物地理分区”一文中详细阐述。本文着重对贵州寒武系一些主要地层单位的含义、使用范围、变化幅度,以及生物分带及对比(见对比表1,2)等进行讨论,希望地层单位的使用能合理反映岩相及生物相的变化规律。金沙岩孔和凯里南皋寒武系剖面是贵州重要的层型剖面。金沙岩孔剖面补充了刘之远1940年所创建、张文堂等(1964)所厘定的牛蹄塘组、明
The Cambrian strata in Guizhou are widely distributed, and the lithofacies and biofacies change rapidly in vertical and horizontal directions. For the classification and variation of lithofacies and biofacies in different periods and the corresponding palaeogeographic environment, Biogeographical division "in a text elaborate. This article focuses on the meaning, scope of application, range of variation, and zonation and contrast (see Comparison Tables 1 and 2) of some major Cambrian formations in Guizhou Province. It is hoped that the use of formation units can reasonably reflect the facies and biology Phase of the law of change. The Jinshayan hole and the Cambrian Nan’ao Cambrian section are important stratigraphic sections in Guizhou. Jinsha rock hole profile to add Liu Zhiyuan created in 1940, Zhang Wintang (1964) determined by the Niutitang group, Ming
