Fault Distribution Inferred from Gravity Anomalies in the Northern France and Its Adjacent Areas
Using Bouguer gravity data, the information on faults has been obtained by means of horizontal directional derivative processing, vertical derivative and wavelet analysis.And according to synthetic analysis with geological data, fault zones distribution map of Northern France and its adjacent areas is presented.We have not the exact depth of the three wavelets details map, but we still can determine the relative spatial relations among faults of different scale and different depth.The northwest trending fault and the northeast trending fault control the structure in the study area.There are also a few south-north trending faults.The structure is quite complicated.The faults with different direction cut each other.The faults outline the boundaries of the basins, grabens and intrusive bodies.
