Abstract: By using SSFM simulator of finite element method, this paper presents the simulation of tectonic stress field in the southern margin of Junggar basin during Himalayan movement.The results show that the southern margin of Junggar basin during Himalayan movement is in compressional environment on the whole and characterized by compressive stress.The high value zone of maximum principal stress is mainly distributed in the north Tianshan mountain and its front, and the low value zone of it is at Bogda mountain.From south to north at the west section of the southern margin of Junggar basin, the high-to-low stress trend appears, but at the east section the stress trend is from low to high in circle way from Bogda mountain to surroundings.The minimum principal stress trajectory assumes zonal distribution with trend NWW at the west section and arch distribution at the east section, similar to the faulting strike and major structural line.At last, this paper discusses the dynamic mechanism of forming stress field of the southern margin of Junggar basin during Himalayan movement by study of these stress fields.
