山东省侏罗－白垩纪岩石地层清理意见

ON THE DIVISION AND CORRELATION OF THE JURASSIC-CRETACEOUS LITHOSTRATIGRAPHIC UNITS IN SHANDONG PROVINCE

摘要:

运用多重地层划分进行山东省地层清理研究中，对中生代侏罗－白垩纪岩石地层划分得出一些新认识。提出蒙阴盆地及其周围的汶南组与淄博地区的三台组属同物异名，故泣南组名应废弃。山东省侏罗系只有坊子组、三台组一个地层序列，将二者合建淄博群。并按岩石地层划分原则，以岩石组合特征为依据，对白垩系进行了划分、对比，建立了区域地层格架，理顺了莱阳群、青山群、大盛群、王氏群各单位间相互关系，避免了同名异物和同物异名等现象，４个群共划分组级单位２２个。

Abstract:

In study of the stratigraphy in Shandong province based on the princpkof multipledivision and correlation. some new knowledge has been gained from the division of theJura ssic-cretaceous Lithostratigraphic. It is suggesfed that the Wennan formationoccurred in the Mengyin basin and its surrounding area is equivalent to the Santaiformation in the Zibo area though the two names are different,so the name(term)Wennan formation should be abandoned.In terms of the Jurassic,only one stratigraphicsequence of the Fa...
