谷露盆地西缘断裂晚第四纪活动初步研究

该文通过遥感解译及实际地质调查,将谷露盆地西缘断裂自南向北分为6段: 年波—顶莫多段、 顶莫多—巴仁多段、 巴仁多—得木来段、 得木来东侧—过龙孔玛段、 过龙孔玛—烟它段、 烟它—凶欧错北段。从地质和地貌现象上证明,谷露盆地西缘断裂既有正断的垂直运动,也有右旋的水平运动。由位错量显示,无论是垂直运动还是水平运动,都是多次活动的结果。

Preliminery Studies on the Late Quaternary Activity of the Western Margin Fault of Gulu Basin,Tibet

Based on remote sensing data and field investigation results,we divide the western margin fault of Gulu basin into six segments,including Nian Bo-Ding Moduo,Ding Moduo-Ba Renduo,Ba Renduo-De Mulai,West of De Mulai-Guo Longpama,Guo Longpama-Yan Ta,Yan Ta-North of Xiong Oucuo.From the geological and geomorphological phenomena,we conclude that the fault moves not only in the vertical direction but also in the horizontal direction.Furthermore,the displacement displays that the movement of the fault has actived ...
