摘　　要：白音查干凹陷断层活动对沉积起着明显的控制作用。北部陡坡断层沉降速率大 ,使得该区霍恩和冬屋地区成为持续发育的沉积中心。变换构造带在白音查干凹陷主要表现为调节带 ,在凹陷的北坡桑合西地区、古尔地区是持续发育的横向调节带 ,地貌上为持续存在的古构造高 ;南坡的白音查干调节带与达 1井东调节带 ,分别是锡林好来与达尔其辫状河三角洲体系。Fault activity in Baiyinchagan depression obviously control sedimentation. The largest subsidence rate of the fault on the steep slope make Huoen area and Dongwu area, both locate on the northern abrupt slope to be sustained depocenters. Converted tectonic belts in the depression are all tectonic accommodation belts. The accommodation belt in Guer area and west Sanghe area, both lie on the northern slope of the depression, is transverse and sustained, and the topography is ever-existing palaeohigh. Both Baiyinchagan accommodation belt and east Da-1 accommodation belt on the southern slope are watershed divides. The former is the watershed divide between the braid-river delta system of Xilinhaolai and Da'erqi and the latter between the sedimentary system of Da'erqi and Wengte.
