Abstract

In the inverse solution of a gravity problem when the direct method of interpretation is not effective, the interpretation is done by assuming a geometric model of the subsurface mass distribution based on geologic or some other considerations, calculating the gravity effect of the model, and finally matching with the observed anomaly curve. The model is repeatedly changed until there is an agreement of the theoretically calculated and observed anomaly curve. Again for estimation of terrain effect, it is necessary to compute the gravity from the known mass distribution. So the importance of direct potential problems in gravity should not be overlooked.
