Combined with the analysis of characteristics of regional geological structure, outcrop observation, regional seismic profile structure interpretation, drilling, logging and non-seismic data, the characteristics of structure evolution and its sedimentary response have been studied. The results show that the fore mountain belt at south margin of Junggar basin was an extensional depression at the Mesozoic, and was a strike-slip compressive depression at the Cenozoic, but do not have the characteristics of the typical foreland basin. Also it experienced times of development phases and the structure features formed later. The basin tectonic boundary is the complex of multiphase fracture combination, and the composite of fault and unconformity, which had the characteristics of split and three-dimensional fracture system. It could divide into four layer composite boundaries, which are interpreted as four sections of composite boundary structure type. At last the extrusion shrinkage in different geological periods and the total extrusion shrinkage in Middle Cenozoic were approximate and quantitative calculation at the southern margin of the basin fold belt by using the method of preparation of structural development section. The structural evolution characteristics effectively controlled the sedimentary of the basin.
