江苏南部Z-8井高家边组胞石生物地层

Chitinozoan Biostratigraphy of the Kaochiapien Formation of Well Z 8 in South Jiangsu

通过对Ｚ－８井志留系高家边组地层中胞石的研究，共鉴定３属８种，从上到下共确立了Ｃｏｎｏｃｈｉｔｉｎａｔｒｕｎｃａｔａ带、Ｃ．ｒｏｓｉｃａ带和Ｂｕｒｓａｃｈｉｔｉｎａｒｅｃｔａｎｇｕｌａｒｉｓ带３个胞石带，进行了地层对比，并指出Ｃ．ｒｏｓｓｉｃａ带在本区高家边组地层中是首次发现。

In this paper eight chitinozoan species belonging to 3 genera have been identified after studying chitinozoans from the Kaochiapien Formation of Well Z 8 in South Jiangsu. Three biozones from lower to upper are the Bursachitina rectangularis, Conochitina rossica and Conochitina truncata Zones. The chitinozoan bearing strata of Well Z 8 were correlated with those of the other wells or sections in Jiangsu and pointed out that the Conochitina rossica Zone was found from the Kaochiapien Formation for the first time in Jiangsu.
