Esm. Abdelrahman et Tm. Elaraby, A LEAST-SQUARES MINIMIZATION APPROACH TO DEPTH DETERMINATION FROM MOVING AVERAGE RESIDUAL GRAVITY-ANOMALIES, Geophysics, 58(12), 1993, pp. 1779-1784
We have developed a least-squares minimization method to estimate the
depth of a buried structure from moving average residual gravity anoma
lies. The method involves fitting simple models convolved with the sam
e moving average filter as applied to the observed gravity data. As a
result, our method can be applied not only to residuals but also to th
e Bouguer gravity data of a short profile length. The method is applie
d to synthetic data with and without random errors. The validity of th
e method is tested in detail on two field examples from the United Sta
tes and Senegal.
