Abstract

Abstract:

By far,there have been only a few neotectonic studies of the Qianliyan Uplift. In recent years,we have gathered multi-channel seismic data covering the whole uplift. After interpretation,we recognized three major Quaternary faults/fault zones. They are the South Boundary Fault Zone(SBFZ),F₃,and F₂ from south to north,respectively. These faults are almost parallel each other and trend northeastward.The SBFZ on most sections has been active at least since the middle Pleistocene; some segments of SBFZ are active since the Early Pleistocene.The latest activity of F₂ is in the Early Pleistocene while that of the F₃ is in the Middle-Early Pleistocene.The deformation intensity of SBFZ varies along strike and is well correlated with the curvature of the fault trace, that is,big curvature correlates with big deformation intensity. This correlation implies a NW maximum principal stress that may be caused by the relative convergence of the Philippine Sea Plate and the Euro-Asia Plate.The map of earthquake epicenters (≥M_S 3.0) shows that there are several earthquakes distributed roughly along the SBFZ.Considering the relative intense deformation of SBFZ,we propose that great attention should be paid to the seismic risk of SBFZ.

摘要：

前人对南黄海北部千里岩隆起带的活动断裂研究开展较少,文中利用908专项地球物理调查获得的覆盖整个千里岩隆起带的多道地震数据,在钻井及其他地震资料进行层位标定的基础上,对研究区的第四纪断裂活动性进行了研究。研究表明,千里岩隆起带主要的第四纪活动断裂(带)有3条,从南至北依次为千里岩南缘断裂带、千里岩隆起带3号断裂和2号断裂。这几条断裂(带)基本平行,均为NE走向; 在剖面上断裂都较为平直。千里岩隆起带南缘断裂带最新活动时间在大部分剖面上至少为中更新世,部分区段为早更新世; 千里岩隆起带2号断裂最新活动时间为早更新世; 千里岩隆起带3号断裂最新活动时间为中-晚更新世。千里岩隆起带南缘断裂变形强弱走向上有变化,变形强弱和断裂平面轨迹的曲率呈现很好的对应关系,曲率大的地方变形强,曲率小的地方变形弱,暗示主压应力为NW向,可能源于菲律宾板块和欧亚板块的NW向汇聚作用。沿着千里岩隆起带南缘断裂带有一些3级以上地震分布,考虑千里岩隆起带南缘断裂带第四纪的变形较强,因此认为这条断裂带发生大地震的可能性比较大。
