江苏下扬子区古生代胞石序列划分及其应用

Classification of Sequence of Lower Yangtze Palaeozoic Chitinozoans and Its Application

对江苏下扬子区古生代所发现的胞石进行了划分,建立了18个胞石带,其中奥陶系五峰组1个胞石带、志留系高家边组6个带、坟头组10个带、泥盆系五通组1个带。运用这些胞石序列对圣科1井进行了地层划分对比,将圣科1井志留系坟头、高家边组划分为5个胞石带。

Classification is made on the chitinozoans found in Palaeozoic of Lwer Yangtze area, 18 chitinozoaos zones are established, of which there is 1 chitinozoan zone in Wufeng Formation of Ordovician system, 6 chitinozoan zones in Gaojiabian Formation of Silurian, 10 chitinozoan zones in Fentou Formation and 1 in Wutong Formation of Devonian system. Contrast of stratigraphic classifications made on Well Shengke 1 by using the chitinozoan sequences. Five chitinozoan zones are divided in Fentou Formation and Gaojiabian Formation of Silurian of Well Shengke 1.
