摘要
///In order to find out regional stress field setting of active structure movement, the authors collected rock acoustic emission samples in Sishichang and Kuqa River section in the north margin of the Tarim Basin, and then experiment with Silurian, Triassic, Permian samples, rock ground stress test of acoustic emission. The recorded results of the maximum principal stress were 57.74, 57.73 and 58.86 MPa, respectively. Summarized previous research results of study area, the rocks recorded the ground stress of the Himalayan movement about 57 MPa, in the northern margin of the Tarim Basin. Late Himalayan period had been suffered intensively, during the geology history stage of the northern margin, since Silurian period.
