Abstract

Generally the quantitative interpretation of the fault uses a 2D model. But if the depth and extension of fault increase, the inversion results will have a bigger error because the 2d model is not fit the real fault. In this paper, we put forward a 2.5D model based on the hexahedron and an inversion method of constraint gravity-vertical fault. The inversion result is better than the 2D model through the model tests. Based on this model, we quantitatively interpreted the Bouguer gravity anomaly of the Sierra Nevada Region in USA.
