Em. Abdelrahman et Tm. Elaraby, DEPTH DETERMINATION FOR BURIED SPHERICAL AND HORIZONTAL CYLINDRICAL BODIES - AN ITERATIVE APPROACH USING MOVING AVERAGE RESIDUAL GRAVITY-ANOMALIES, Journal of the University of Kuwait. Science, 22(1), 1995, pp. 114-122
The present paper deals with a simple numerical approach to estimate d
epths of a buried sphere and horizontal cylinder using moving average
residual gravity anomalies. The problem of depth determination has bee
n transformed into finding a solution of a non-linear equation of the
form f(z) = 0. Formulas are given to estimate the radius of buried str
uctures. The method has been applied to synthetic data with and withou
t random errors. The validity of the method is also tested on the Humb
le Dome gravity anomaly, near Houston, USA.
