中国北部以昆仑-秦岭-大别复合造山带为南界,其东部经受了构造体制转换、华北克拉通分化和“活化”以及岩石圈大范围大幅度减薄。西部特提斯构造域的中、小地块多次“开”和“合”、印度-欧亚板块碰撞和青藏高原隆升及其直接效应等重要地质事件都发生在中国北部,并由此导致北部盆地的扩张、萎缩、迁移、复合和叠合等复杂变化。中国北部盆地类型繁多,盆地演变频繁, In the northern part of China, the Kunlun-Qinling-Dabie Composite orogenic belt is the southern boundary, and its eastern part has undergone structural transformation, North China craton differentiation and “activation” and a large-scale lithospheric thinning. Many geological events in the western Tethyan tectonic domain have occurred many times in the northern part of China, such as the Indian Ocean Eurasian plate collision and the uplift of the Qinghai-Tibet Plateau and its direct effect. , Resulting in complex changes such as expansion, shrinkage, migration, compounding and superimposition in the northern basin. There are many types of basins in northern China, with frequent basin evolutions,
