| 摘 要： | 河西走廊东部晚古生代前陆盆地从形成、稳定发展到收缩消亡的过程，反映了泥盆纪是主要成盆期，奠定了盆地的基本格架；石炭纪是盆地稳定发育阶段，也是盆地内煤、油气的主要形成期；自二叠纪至三叠纪，前陆盆地应变停止，应力粘弹性松驰，被重力作用下的山前盆地所取代。

| Abstract: | The process,which is late Palaeozoic foreland basin from forming,developing steadily tocontraction consuming of the eastern part of Hexi Corridor,showed the Devonian was mainlystage of formation basin and laid a fundamental framework of the basin; during the Carboni-ferous,it is the basin developed stage steadily,and the forming stage of coal and oil -gastoo. From the Permian to the Triassic,the strain of the.foreland basin went to the end andstress viscoelasticity relaxed,then the piedmont basin was instead of the foreland basin un-der the gravity. |
