By the field geological survey and comprehensive study of typical seismic and structural history profiles�� the authors systematically discussed on the control of deep-large fault to fault basin group�� The target region is divided into three first-class tectonic regions from south to north��including western Liaoning basin��northern Liaoning basin and western Jilin basin by the Xilamulunhe --Changchun --Yanji suture belt and the translithospheric fracture in Chifeng--Kaiyuan�� The northern Liaoning basin is divided into three second-class fault depression regions�� including west��mid--west and mid--east regions based on the basin-control fault��the spatial and temporal distribution of the fault basin group��the structure type of fault depression and the stretching quantity in different periods�� The formation and distribution of western fault depression was controlled by Xilamulunhe fault�� The effect of controlling basin between Nenjiang--Balihan and Sunwu--Daqing--Fuxin faults to the fault depression in mid--west was relatively same�� Both the Sunwu--Daqing--Fuxin and Jiamusi--Yitong faults performed a very important controlling function to the mid--east fault depression region�� Changtu fault depression was mainly controlled by Jiamusi-- Yitong fault�� The northern Liaoning basin region��as a graben��has the fault depression group not only controlled by the fault in NNE direction but also by the re-movement of Xilamulunhe fault and Chifeng--Kaiyuan fault in near EW direction�� The stretch rate of fault depression region in the mid--west diminished gradually from the deposit period of Jiufetang Group to Shahai Group and then to Fuxin Group�� There was a great difference between the mid--east and mid--west fault depression regions��which was caused by the deep-large faults in NNE and near EW directions in different control degree��
