Abstract

This paper emphasizes the basic ideas behind the usefulness of the least-squares method in determining the optimum depth to a buried spherical body from second vertical derivative maps by finding a solution of a non-linear equation in the form of f(z) =O. The derived formulae can be directly computerized. The depth to the center of the Humble Salt Dome. estimated by our present approach, is found to be comparable with other literatures previously published.
