【摘要】 利用地貌和新近系位错测量的方法,结合遥感、地貌、变形测量与新近纪测年等手段,重点研究了伊犁盆地喀什河断裂中更新世以来的垂直活动速率。喀什河断裂在中更新世以来的新活动主要表现在河流阶地和地层的位错,综合研究了这些位错数据,分析了断裂各段在中更新世以来的活动速率,讨论了1812年尼勒克地震的平均位错反映的断裂现今最新的活动速率,提供了喀什河断裂中更新世以来不同时期活动的定量数据,填补了天山内部新近纪晚期研究的部分空白,对现今地壳运动与地球动力学研究及减轻地质灾害有重要意义。更多还原

【Abstract】 Using physiognomy and neogene offset methods,combined with remote sensing,physioghomy,deformation measure and neogene dating and so on,to study the vertical activity velocity of Kashi river fault in Yili basin since middle pleistocene.The fluvial terrace and stratum offset are the main new activity in Kashi river fault since middle pleistocene,summarized the datum,analyzed the activity velocity about every segment in the fault since middle pleistocene,discussed the new activity velocity nowadays reflected by average offset of Nileke earthquake occurred in 1812,offered ration datum of activity in different period in Kashi river fault since middle pleistocene,it fills up the part blank of the late neogene inside Tianshan,and it is important meaning for crustal movement nowadays,geodynamics and reliefing geologic disaster更多还原
