摘要
在晚古生代东北及其邻区属于一个稳定的地块——佳—蒙地块认识基础上,通过地层展布分析,识别出东北地区晚古生代地层分属于佳—蒙地块的北缘、南缘和东缘沉积,即东北地区晚古生代地层分别由佳—蒙地块的北缘、南缘和东缘三套大陆边缘沉积组成。将这三套大陆边缘沉积区域分别命名为兴安地层区、内蒙古草原—松花江地层区和宝清—东宁地层区,统归佳—蒙地层大区。在此基础上,编制了东北地区晚古生代岩石地层对比表。
Based on the understanding that northeastern China and its adjacent regions belong to a stable block (i. e. the Jiamusi-Mongolia Block) during late Paleozoic, two depositional belts of the Upper Paleozoic strata were recognized on the north and south margins of the Jiamusi-Mongolia Block in northeastern China by the analysis of stratigraphic distribution. Late Paleozoic strata in northeastern China are composed of two sets of continental margin deposits, corresponding to the north margin and south margin of the Jiamusi-Mongolia Block. Thus, from the stratigraphic provincialism veiwpoint, two stratigraphic regions, i.e. the Hsingan Stratigraphic Region and the Inner Mongolia Grassland-Songhuajiang Stratigraphic Region, can be recognized for the whole Jiamusi-Mongolia Stratigraphic Realm. Finally, a new chart of the Upper Paleozoic stratigraphic correlation in Northeast China is presented here.
