| Abstract | ||
| A new method, depends on the determination of the horizontal and vertical gradients of gravity data, is introduced for estimating the depth of gravity source. The distance of the nearest intersection point, of horizontal and vertical gradient, to the central axis of the gravity anomaly (x) is found to be related directly to depth of gravity source. Two relations were obtained to estimate the depth of the source that is approximated to spherical or horizontal cylinder bodies. The suggested method is applied on four groups of gravity data, where the depths to the sources are well known, and the results are generally confirming the actual depth. The introduced method is applied for two gravity anomalies in Iraq of which the depth is unknown and acceptable results are obtained. | ||
