| 摘 要： | 采用高精度的浅层地震勘控方法和先进的数据处理技术，查明了玛纳斯地震区玛纳斯背斜的浅部地壳结构特征，它主要由一个逆掩推覆构造和两个局部背斜组成，存在一条盲断层和两知地表出露断层，结合附近地质资料和钻井资料，确定了每条断层的活动年代，为进一步研究该区的深浅部构造之间的关系和玛纳斯地震的发震机制提供了可靠的浅层资料

| Abstract: | The shallow crust structure characteristics of Manas anticline in Manas earthquake area are studied using high precision shallow seismic prospecting method and advanced data processing technique. The anticline consists mainly of an overthrust nappe and two partial anticlines, and includes a blind thrust and two surface active faults. Active age of every fault is determined by geological data and drilling data nearby. It provides reliable shallow data for further studying of the relation between deep structure and shallow structure and seismogenic mechanism of Manas earthquake. |
