本文是中国陆域航磁地质构造研究最新进展的综述性文章,对基于航磁数据的中国陆域地质构造编图最新成果和取得的新认识进行了论述。该项研究利用我国50多年的海量实测航空磁测数据,采用最新的数字化编图技术及先进实用的位场数据处理方法编制了1:5000000万和1:1000000万中国陆域航磁系列图件,以板块构造和大陆动力学理论为指导,以岩石物性研究与航磁异常特征分析为基础,定性、定量与综合解释相结合,编制了中国陆域磁性基底深度图及主要地质构造单元图件,并依据航磁数据对新划分的地质构造进行了论述。
This article is a review article on the latest advances in the study of China’s terrestrial aeromagnetic structures, and discusses the latest achievements and new understandings of China’s terrestrial geological structures based on aeromagnetic data. This study made use of the massive measured aeromagnetic data of more than 50 years in our country and compiled the 1: 5000000 and 1: 1000000 Chinese land-space magnetic series pictures by adopting the latest digital map-making technology and advanced and practical data processing methods of the field. Based on plate tectonics and continental dynamics theory, based on petrophysical properties and aeromagnetic anomaly characteristics analysis, qualitative, quantitative and comprehensive interpretation are combined to prepare the Chinese terrestrial magnetic substrate depth map and the main geological structural units According to the aeromagnetic data, the newly divided geological structure is discussed.
