| 摘 要： | 以新的地层对比意见为基础，通过对华北石炭二叠纪海相层（石灰岩和海相泥岩）分布的详细研究，应用高分辨编目技术，完成了石炭二叠纪各期海侵范围及海侵方向图件的编制，并着重指出：①在晚石炭世早期（晋祠期）以前，郯庐断裂以西的海侵方向主体为由东向西，海侵作用中心具有由南向北迁移的规律；②自晚石炭世晚期（太原期）开始，华北盆地构造发生大的变动，古斜坡由北倾变为南倾。海侵作用发生在盆地南东和北酉两个方向上。这种构造变动及海侵方向的变化与盆地周缘板块构造活动有关；③自中石炭世晚期至晚石炭世晚期，华北海与祁连海可能一直保持程度不同的连通，而与扬子海则是在晚石炭世晚期才直接连通的。

| Abstract: | n the basis of new viewpoint of stratigraphic correlation and by using highresolution map-making technology, a series of maps about transgressive rangs and directionshave been finished through the detailed study marine beds(limestons and marine mudstons) distributions in Permo-Carboniferous System of North China. The authors point out that:(1) the transgressive directions were mainly from east to west on the west side of Tanlu fault before the early stage of Late Carboniferous (Jinci Stage),and the transgressive centres migrated regularly from south to north;(2) the important tectonism took place in Huabei basin during the late stage of Late Carboniferous (Taiyuan Stage), and the Paleo-dip changed from north-dip to south-dip;the transgressions occurred at the twodirections of southeast and northwest in the basing the changes of tectonic and transgressive directions dealt with the movements of the plates around the basin;(3)it was probably that Huabei sea linked up with Qilian sea to a certain degree from the late stage of Middle Carboniferous to the late stage of Late Carboniferous,and linked up directly with Yangzi sea after the late stage of Late Carboniferous. |
