The investigation of optimal regularization parameter for potential field transformation

We have investigated the morphology of the negative regional gravity anomaly with maximal value near 300 mGl at different altitudes (Sierra Nevada Batholith). This gravity anomaly spatially coincides with the structures of San-Andreas and Calaveras faults (20–55 degrees S and 90–140 degrees W). In this paper we apply the technique of filtration of the long- and short-wave components of the amplitude spectrum of anomalies, using numerical methods of field simulation at various altitudes. For creation the multilayer gravity model of the Earth crust we need to know the field morphology of different earth layers. For this purpose we have investigated the optimal regularization parameters for gravitational field transformation.
