The Application And Research Of Gravity And Magnetic Data Processing And Interpretation In Alashan Area Of Inner Mongolia

This thesis relies on the project of aeromagnetic anomaly verification in the region of Inner Mongolia ALaShan.The main gravity and magnetic anomaly in the study area and the typical gravity and magnetic profile anomalies are taken as the research object,According to traditional methods,the abnormal data extraction,analysis and explanation have been carried out,besides,combing the distribution of ore body of the studying region that based on drilling data,we analyzed the application effect of the combined gravity and magnetic exploration method technology in areas with low research such as Gobi.This paper is based on previous geology,geophysical and geochemical studies,and previous data has been fully analyzed.Through processing such as poling,extension,field separation and derivation,we deduced five local abnormal in high magnetic anomaly C1.Furthermore,by using 2.5D joint inversion of gravity and magnetic data and tangential profile inversion of drilling data,we analyzed the deep state and distribution of magnetic body beneath the study area,and get good results,which can provide theoretical and technical reference for the further research.
