一、几个主要沉积区域的范围自震旦纪以来,经过古生代和三叠纪,直到燕山运动时期(侏罗纪晚期到白垩纪末),广大的中国东部出现了而且持续着几个主要沉积区域,和隔离它们的侵蚀区域——长时期的地背斜构造或古陆区。它们的范围和彼此的关系如下: 满蒙沉积区:主要是内蒙北部和大部满洲地区(所谓北满);是古生代地槽型沉积区。内蒙侵蚀区:内蒙南部、山西、河北和辽宁的北 First, the extent of several major sedimentary regions Since the Sinian, through the Paleozoic and Triassic, up to the Yanshanian period (from the Late Jurassic to the end of the Cretaceous) vast areas of eastern China appeared and continued with several major deposits Regions, and the eroded regions that isolate them - the long-term anticlinal structures or ancient land regions. Their range and their relationship to each other are as follows: Manchu Deposition: mainly in northern Inner Mongolia and most of Manchuria (the so-called North Manchurian); is the Paleozoic sedimentary area. Inner Mongolia erosion area: southern Inner Mongolia, Shanxi, Hebei and Liaoning north
