The spatial heterogeneity of the lithospheric mantle beneath north china may have resulted from the diachronous thinning processes 华北岩石圈组成的空间不均一性可能与岩石圈减薄过程的时空差异有关。

This indicates that the exhumation of the dabie orogenic belt was diachronous , and that its uplift happened from east to west and was mainly controlled by the ne fault system 揭示了大别山造山带的折返是穿时的，隆起自东向西进行，而其控制因素主要为ne向的断裂体系。

Given the fact that mesozoic magmatism was closely related to the lithospheric thinning , it is proposed that the diachronous lithospheric thinning is the main mechanism by which the taihangshan gravity lineament was formed 由于岩浆作用与岩石圈减薄作用密切相关，因此认为华北岩石圈减薄的时空不均一性是形成太行山重力梯度带的重要机制。

6 . the mesozoic sedimentation in the north margin of the dabie orogenic belt is diachronous . from east to west , the onset of the sedimentation is successively in lower - middle jurassic , middle - later jurassic and lower cretaceous 大别山北缘中生代沉积作用具有穿时特征，沉积作用开始时间自东向西依次为早中侏罗世、中晚侏罗世和早白垩世。
