摘要: 前言笔者与地矿部第二石油指挥部地质大队下古生界专题队合作,对山东莱芜,龙古1、2、3井,嵩山、峰峰、唐县、京西诸剖面(图1)的奥陶系进行了沉积相和沉积环境方面的工作。根据所得资料,对华北地台东部奥陶系南北向沉积特征提出一些认识。华北地台东部是指华北地台太行山以东的部分。现在,大量资料证明,华北地台东部与西部在奥陶纪有诸多不同。本文仅讨论东部沉积环境南北向的变化特点。Abstract: North-China Platf orm is one of the largest platforms in Chinas to the west, it goes beyond Helaashan M ountains； to the south,tains, Qinling Mountains, east, it reaches to the Bohai F uniushaa M ouatains it stretches to and Dabieshan Qilianshan Mountains Moun-to the Sea and the East China Seas farther than Yinshan M ouataias.In Early Ordovician, it sate platform. to the north, it extends was a very broad carbo nate platform.
