This process of separation is known as regional residual separation for which a variety of methods are available (Kearey et al. 2003; Telford et al. 1998). The gravity method also enables a prediction of the total anomalous mass (ore tonnage) responsible for an anomaly. Gravity method detects only lateral contrasts in density.
