The Spatial Different Order Derivative Method of Gravity and Magnetic Anomalies for Source Distribution Inversion

Gravity and magnetic measurements are common remote sensing strategies to obtain the property change of observed targets. Nowadays, characteristic value derivatives gravity anomalies is commonly used detect source horizontal edge. We found that coordinates different-order not directly corresponding edge source, which varies with depth size source. The spatial derivative (SDD) method was developed, we proved intersection location this feature simultaneously. model tests SDD has high accuracy strong anti-noisy. According relationship between potential field data lithology, delineate metalorganic area in survey region, provides basis for subsequent exploration.
