贵州的震旦系、寒武系分布广泛,发育良好,化石丰富,是解决华中—西南区震旦系与寒武系分界及其对比的重要地区。1974年以来,不少单位在织金、纳雍、清镇和习水等地梅树村期地层中,发现了带壳动物化石。本文着重讨论贵州震旦系、寒武系的分界,及与相关地层的对比。 The Sinian and Cambrian systems in Guizhou are widely distributed, well-developed and rich in fossils. They are important areas for resolving the boundaries between the Sinian and Cambrian systems in the central-southwest China region and their contrasts. Since 1974, many units have found fossils of shelled animals in the Meishucun formation of Zhijin, Nayong, Qingzhen and Xiushui provinces. This article focuses on the demarcation of the Sinian and Cambrian systems in Guizhou and their correlation with the related strata.
