摘　　要：贵州早寒武世早期普遍存在一套黑色页岩。通过对麻江羊跳、铜仁、遵义中南、遵义松林小竹、天柱大公塘剖面实地考察与地球化学分析,认为贵州早寒武世黑色页岩是在缺氧环境下,热水沉积为主导,同时受陆源强烈影响,是海水、生物和地球深部物质共同作用下形成的.There is a black shale which widespread at Early Cambrian in Guizhou. This paper speculated there is an outcrop close to the deep-water basin from the geochemistry analysis and explore on the spot to Majiang Yangtiao, Tongren, Zunyi Zhongnan, Zunyi Songlin Xiaozhu, Tianzhu Dagongtang sections. The black shale formed in a special environment which is anoxic. It leaded by hydrotherrnal process and land- carriage, also, by the impact of biological and deep earth material formed under the joint action.
