晚三叠世,济源盆地南部与北部的岩相古地理面貌及充填特征存在着明显的差异;早中侏罗世盆地南部隆起,北部继承性沉降,直到中侏罗世未盆地完全封闭。这种差异是由盆地内部黄河断裂的同沉积活动造成的。
In the Late Triassic, the lithofacies palaeogeographic features and filling features of the southern and northern Jiyuan basins are obviously different. The early Middle-Middle Jurassic basin raised up in the south and the northern subsidence continued until the Middle Jurassic basin was completely closed. This difference is caused by the same sedimentation activity of the Yellow River fault in the basin.
