To overcome this ambiguity, “a priori” information is introduced by minimizing a functional that describes the geometrical or physical properties of the solution. This paper presents a 2D gravity inversion technique incorporating axes of anomalous mass concentration as constraints. The inverse problem is formulated as a minimization of the moment of inertia of the causative body with respect to the axes of the mass concentration. The proposed method is particularly applicable to homogeneous, linear mass distributions, such as mineralization along faults and intruded sills or dikes. Inversions of synthetic and field data illustrate the versatility of the implemented algorithm.

The availability of the new technique is rather limited only to airborne gravity surveys with a very specific instrumentation. In principle, the gravity gradients can be calculated from the vertical component of the gravity field commonly measured in a ground-based gravity survey. We present the calculation of the Full Tensor Gradient (FTG) of the gravity employing the Fourier transformation. The calculation was applied to synthetic data associated with a simple block model and also with a more realistic model. The latter corresponds to a 3D model in which a thin coal layer is embedded in a sedimentary environment. Our results showed the utility of the FTG of the gravity for prospect scale delineation.
