The meso - cenozoic evolution of bachu fault - uplift is closely related to its south and north subsiding foredeep. under the background of indian plate subducting under asia - europe plate, bachu forebulge was greatly affected by the development of southwest depression and awati depression. almost all of its structure reversed, and as a result of it, both of its south and north boundary migrated. according to its evolution history and its feature, the authors tentatively use both - side migration model to interpret the evolution of compound forebulge. since triassic, almost all the spheres above lithosphere synchronously became flexure. because transpressional stress field became increasingly strong, bachu forebulge continued uplifting and big faults formed. then, bachu uplift, as a whole, slipped upward along those big faults and showed migrating toward thrust zone in plane. in tectonic tranquility, the lithosphere bounded back and in consequence of it, bachu uplift slipped down and showed migration toward craton, at that moment negative inversion structures developed. while the forebulge migrated toward its south and north foredeep, it was very possible that locally extensional stress appeared in the forebulge
