摘要
利用高精度航磁资料采用对应分析、图像处理、人机交互等新方法及各种常规处理手段,并结合地质和其它地球物理资料对研究区结晶基底的起伏状态、性质、居里面起伏变化特征以及深部断裂构造的展布格局等作了研究;计算了该条带域地壳磁层上、下界面深度;圈定了各类火成岩体的分布范围以及不同级次的断裂构造11条;指明了基底岩相的分布特征;阐述了结晶基底以及居里面起伏变化特征。
The high resolution aeromagnetic data from Laohutai-Hetian belt were processed with routine techniques such as corresponding analysis, image processing and user-computer interactive system. Some convertional methods were also applied to the study, which were reduction to the pole, upward continuation, 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 topography, property and Curie surface of the crystalline base ment and deep fault structure of the studied area. Geology and additional geophysical data were also involved in the sutdy. Finally we evaluated the potential of oil and gas in the belt.
