Anomaly separation has always been the focus of gravity and magnetic data processing. Interpolation cutting is a spatial potential field data separation method, which has different effects on different nonlinear parts of the gravity and magnetic anomalies, so as to improve the resolution of different feature anomalies. It can be applied to denoising, anomaly separation and 3D imaging. In this paper, based on the problems encountered in the process of model and actual data processing, the interpolation algorithm is improved, and the effects before and after the improvement are compared. The improved interpolation cutting method was used to process the gravity and magnetic data of a certain exploration area in western China. Good results were obtained in the extraction of deep gravity anomalies and the three-dimensional imaging of igneous rocks.
