塔里木盆地东部边缘区深部构造研究

THE DEEP STRUCTURE STUDY IN EAST MARGIN OF TALIMU BASIN

利用高精度航磁资料，应用对应分析、图象处理、人机交互等方法以及多种常规处理手段（化极、上延、滤波、导数、视磁化率、基底和居里面深度等），并结合地质和其它地球物理方法对研究区基底的岩相变化。

In this paper, the high precision aeromagnetic data from the east margin of Talimu Basin were processed with the application of some novel technigues such as correspondence analysis, image processing and user-computer interactive aystem. Some conventional method were also applied to the data, which were reduction to the pole,upward continuation filtering, vertical and horizontal derivatives, apparent magnetic susceptibility mapping and Curie surface and the depth-to-basement determination. The aim of the all processing above listed is to study the changes of basement lithofacies, the undulate state of basment surface and Curie surface, and the pattern of extend and distributed of deep faulting structures in the study area.
