Nomograms For Interpreting Gravity Anomalies Above A Finite Horizontal Cylinder

Abstract

The present study gives a new method for solving the inverse problem of the gravitational anomalies related to a finite horizontal cylinder, by the use of the downward continuation method. Master curves have been obtained for this purpose, besides a detailed explaination of calculating the different parameters of such a causative body. The accuracy of the methods has been also demonstrated with a synthetic model, together with calculated error curves to obtain the corrected depth and length for any cylinder. An interpreted example of a real anomaly in the western desert of egypt has been given using this procedure.
