摘要
Abstract
Baiyintuga area, the Abga Banner, Inner Mongolia is a shallow covering area of geological structures, where the surface structural features are indiscernible. This paper provides a detailed description of the magnetic field characteristics of deep faults in this area and discussion on the application of the aeromagnetic in faulted structure interpretation based on the latest high-precision aeromagnetic data. According to the structure characteristics of magnetic anomaly mentioned above, 15 faulted structures are distinguished in this area based on first derivative of aeromagnetic ΔT vertical directions. The main structures extend as north-east and north-west directions. As for the faults such as F1、F2、F3、F4、F7、F8、F9, located in Baiyintuga area, the lithology in the faulted area mainly belongs to Baoligaomiao Fm. They are rock outcropped areas with well-developed vein rock, among which are principally granite porphyry veins and syenite porphyry veins. The surface exposed dikes are mainly in the north-west direction, which are similar to the aeromagnetic interpretation structure. While the structures are upward extending, they become indistinct, which indicates they have the same base-rock at the bottom. But as for the faults of F5、F14、F15 have much clearer upward continuation, so these faults may be caused by the large fracture in the deep.关键词
