摘要
利用Google Earth影像数据,对发育于克日日岗山地与兴海—同德盆地北东边界的NWW走向的贵南南断裂活动性进行研究。通过对该断裂的遥感解译及野外地质调查认为,该断裂性质以逆冲为主,断裂带全长157km,而相关微地貌(水系、冲洪积扇、山脊等)位错研究则表明断裂带最新活动时代为晚更新世,全新世以来未发现断层活动迹象。
The activity of the NWW striking South Guinan fault that developed in the Keririgang mountain and northeast boundary of the Xinghai-Tongde basin is studied using Google Earth image data.Through remote sensing interpretation and field geological investigation,the fault was found to be mainly a thrust fault with a length of 157 km.Research on microlandform offsets indicates that the fault was last active during the late Pleistocene era and there have been no signs of movement since the Holocene era.
