Aeromagnetic Data Processing And Interpretation And Metallogenic Prediction In Jingning South Gansu Province

It is an important step for regional geological survey to delineate ore prospecting and prediction areas for high precision aeromagnetic survey.How to combine aeromagnetic data with known geological remote sensing borehole and other surface data becomes the key of prospecting prediction.Based on the newly acquired aeromagnetic survey data,this paper conducts data conversion processing,selects abnormal points,and performs lithologic structure mapping and local aeromagnetic anomaly interpretation in the research area.In this paper,the typical ore deposits in the region are selected for in-depth discussion,and the metallogenic rules are summarized and other geophysical and geochemical data are combined for prospecting and prediction.The main contents of this paper are as follows: 1.Regional geological data were collected extensively and metallogenic rules of cu-polymetallic deposits were analyzed;2.The high precision aeromagnetic data can be used to calibrate the data and transform the data potential field,so as to prepare for the later work.3.Regional magnetic field characteristics were analyzed and lithologic structure mapping was carried out;4.The prospective prospecting area was delineated based on other physicochemical telemetry data.
