Joint inversion of gravity and multiple components of tensor gravity data

Journal of Central South University, 2016
Geological structures often exhibit smooth characteristics away from sharp discontinuities. One aim of geophysical inversion is to recover information about the smooth structures as well as about the sharp discontinuities. Because no specific operator can provide a perfect sparse representation of complicated geological models, hyper-parameter ...

Inversion of Gravity Data

2016
The inversion process for gravity interpretation has to treat the intrinsic ambiguities of the gravimetric data; for this reason, the possible investigated models need to be constrained in order to recover the uniqueness of the inversion process. In this work, a novel approach to gravimetric inversion is presented. Geometric information on the existing

Noniterative nonlinear gravity inversion

Geophysics, 1993
Abstract To obtain the shape of a homogeneous body from its gravity anomalies, the inverse of Parker's formula is expressed here by means of a power series expansion in the reciprocal of the density contrast. The calculation of the nth coefficient of the series needs the evaluation of n - 1 Fourier transforms of products and sums of ...
