Abstract

The inverse gravity problem - especially to determine the crystal basement -does not an unique solution so there are many methods to solve it. There is two parts in this paper (a) writing a program to determine the crystal basement from the gravity data using the forced neural network method and (b) applied it to interpret some gravity anomalies in Mekong delta area. The results showed that the program is easy to use and the maximing depth of the crystal basement of Mekong delta area varies from 0.6 km to 1.6 km and these results are suitable with the previous ones.
