华北地台石炭二叠纪若干地层问题

以现代地层学理论为指导，以丰富翔实的地质资料为基础，对华北地台石炭二叠纪的若干地层问题进行了剖析并提出：１）修订并论证了华北地台上古生界最底部的一个岩石地层单位——田师傅组，指出这个组的区域分布和穿时性特征，同时对其实用性也进行了论证；２）讨论了华北地台石炭系－二叠系界线，主张以类Ｐｓｅｕｄｏｓｃｈｗａｇｅｒｉｎａ带底作为二叠系的开始，有利于大区域内的相关地层划分对比；３）讨论并厘定了华北地台本溪组、太原组和上石盒子组等岩石地层单位的含义；４）华北地台东北部确切存在早石炭世沉积，传统的有关该区的地质历史结论应予修正。

On Some Controversies of the Permo Carboniferous stratigraphy in North China Platform

Guided by the theory of modern stratigraphy and based on a large amount of the geologic data,the author has systematically studied and discussed some relevant stratigraphic problems concerning the Permo Carboniferous strata and proposes own opinions: 1) the contents of the Tianshifu Formation,as the lowest practical lithostratigraphic unit of the Upper Palaeozoic in North China Platform,are redefined and revised, and its space time distribution is discussed as well; 2) the boundary between the Carboniferous and the Permian in North China Platform should be drawn at the base of the Pseudoschwagerina zone,which is a feasible boundary; 3) the paper discusses the implications and distribution ranges of the Penchi,Taiyuan and Upper Shihhotse Formations as lithostratigraphic units,and rectifies some errors existing in the past research works; 4) the paper expounds and proves the existence of the Lower Carboniferous in the northeastern part of North China Platform.It is believed that the paper will be very helpful to the further geologic work in the study area.
