Using Newton’s method approach with an initial estimate of 1500 kgm-3 and 3km, we got estimates for the model parameters for the density contrast as 6827 kgm-3 and 24.7 km as the source depth of the Covington pluton (fig.5a, 5b). We reached the estimates after four iterations with a minimum error of 0.5 X 10-3 (fig. 6a), the distribution for the predicted and observed gravity anomaly had a similar distribution (fig.6b).
