华北晚古生代含煤建造分布在阴山和秦岭两个巨型纬向构造带之间,在与其大致相同的纬度中,世界上不少地区在晚古生代也有重要的聚煤作用发生,说明本区是巨型纬向构造带控制的全球性聚煤带中的一个大型聚煤坳陷。这个大型坳陷的南北为纬向隆起带所限,其沉积特征与阴山以北和秦岭之南有明显的差别,西与我国西部河西走廊晚古生代煤系相连,向东延展到国境线。通过建造分析可知,在胶东半岛和辽东半岛,当初仍应有 Late Paleozoic coal-bearing construction in North China was distributed between two giant zonal structural belts of Yinshan and Qinling Mountains. In the same latitude, in many parts of the world, there was also an important coal-forming event in Late Paleozoic, indicating that this area is a giant A large coal accumulation depression in the zonal tectonic belt controlled by the global coal belt. The north-south depression of this large depression is characterized by latitudinal uplift. Its sedimentary features are obviously different from the north of Yin Mountain and the south of Qinling Mountains. The west is connected with the Late Paleozoic coal measure of the Hexi Corridor in western China and extends eastward to the borderline. Through the construction analysis shows that in the Jiaodong Peninsula and Liaodong Peninsula, there should still be
