Abstract
In order to determine the crustal structure from the observed gravity anomalies, the attraction of local geological structure should be removed from the data. In that case it is necessary to calculate the gravitational attraction of the given structure. In two dimensional problems, the "line integral method" developed by Hubbert can conveniently be used for this purpose. In this paper, we have slightly supplemented and extended the method by Talwani, Worzel, and Landisman, and also attempted to investigate the problem of determining the structure from the given gravity anomalies. Several examples are presented to illustrate the applicability of our method.
