摘要
Based on processing and analysis of large-scale and high-resolution aeromagnetic data, the authors distinguished five kinds of local aeromagnetic anomalies related to structural trap. They have to do with basement rocks, basic intrusive rocks, intermediate-acid intrusive rocks, volcanic rocks or sedimentary rocks. The characteristics of each kind of local aeromagnetic anomalies related to structural trap are described in detail in this paper. Combined with seismic, gravity and drilling data, the authors have made geological interpretation of some typical anomalies, thus providing the basis for oil and gas exploration.
