| Abstract: | In order to find and expand the copper polymetallic ore resources around the beach foot copper deposit in Tongling,on the basis of geological and previous geophysical data research,high precision gravity,magnetic and high-power IP sounding profiles are carried out in the periphery of the mining area.After processing and analyzing the obtained data,joint inversion of 2.5 degree gravity and magnetic profile and comprehensive analysis are carried out.According to the principle moving from the known to the unknown,the distribution and buried depth of two concealed diorite bodies and one ore(chemical body)are delineated,and the distribution of one concealed fault structure is inferred.Based on geophysical anomalies and known geological data,the favorable metallogenic area is delineated,which provides geophysical basis for the subsequent drilling engineering construction. |
