第一节研究简史贵州省的中西部和北部,位于扬子地台的西南段。震旦纪至寒武纪地层分布较广,发育良好,属扬子地层区,是研究我国震旦系—寒武系界线的重要地区之一。七十年代初, 贵州区域地质调查大队和贵州105地质大队先后在该区进行区域地质调查和矿产普查工作, 分别在织金、清镇和习水等地含磷岩石中,发现了一些小壳化石,经钱逸(1978年)研究, 初步肯定了该区早寒武世早期地层的存在。但限于工作程度,资料零星且不系统。
The first section of a brief history of Guizhou Province in the central and western and northern, located in the southwestern section of the Yangtze platform. The Sinian to Cambrian strata are widely distributed and well developed, belonging to the Yangtze stratigraphic zone. They are one of the most important areas for studying the Sinian-Cambrian boundary in our country. In the early 1970s, the Guizhou Regional Geological Survey Team and the Guizhou 105 Geological Brigade conducted regional geological surveys and mineral census surveys successively in the area. In the phosphorous rocks in Zhijin, Qingzhen and Xiushui respectively, some small shells Fossils, Qian Yi (1978) study, initially affirmed the existence of early Precambrian strata in the area. But limited to work, data sporadic and not systematic.
