Abstract

Abstract

ETM data reveal that the Yuanmou fault is mainly characterized by horizontal left-lateral and shear strike-slip, including ringent shear and pressed shear in part.Taking the advantage of the level moving and offset of the gullies and ridges in 1∶50000 landform and ETM image, we estimated the activity of Yuanmou fault of Yipinglang-Jiangbian segment in the Late Quaternary, and later the results from field exploration, including the analysis of the profiles of landform offsets such as gullies and fluvial landforms, the sections of the active structures in the studied area and activity and active intensity in the Yuanmou fault is the same as what we presumed before.The result shows that the latest active time of the Yuanmou fault of Yipinglang-Jiangbian segment is from the mid-late of Late Pleistocene to Holocene.During these ages, the level moving velocity of left-lateral strike-slip of Yipinglang-Dalongtan segment is approximately 2.0 mm/a, the velocity of uprightness strike-slip approximately 0.07 mm/a.While the respective velocity of left-lateral strike-slip and uprightness strike-slip is approximately 0.53 mm/a and approximately 0.06 mm/a from Yangtianjing to Mulianjiu, the respective velocity of left-lateral strike-slip and uprightness strike-slip approximately 1.32 mm/a and 0.03 mm/a from Leshenggu to Jiangbian.Comprehensive analysis indicates that the level moving velocity since the Late Quaternary in the studied phase is 1~2.0 mm/a, with a major left-lateral shear strike-slip.
