Gravity interpretation of two dimensional fault structures using Hilbert transforms.

The Hilbert Transform of the second order horizontal gradient of the gravity effect of a two dimensional dipping fault is derived. Using the derivatives of the horizontal gradient of the gravity effect and the Hilbert Transform, the parameters of the dipping fault, namely the dip, the depths to the top and bottom and the density contrast, are obtained. The gravity effect of the vertical fault has also been analysed treating it as a particular case of the dipping fault.-from Authors
