Abstract The characteristics of wavelet can be used to extract important information of airborne gravity anomaly. In this paper, the authors established the geological model using wavelet analysis theory, and then discussed the corresponding relationship between geological body boundary and wavelet magnitude. Based on the airborne gravity data obtained in some sea areas of China, the authors used the maximal value of wavelet magnitude to identify the fracture information in comparison with the airborne Bouguer gravity anomaly and its directional derivative. The result shows that wavelet magnitude can identify the fracture, especially in the area with fuzzy result of the airborne Bouguer gravity anomaly and its directional derivative.
