Convergence of iterative gravity inversion
GEOPHYSICS, 1986Oldenburg (1974) presented an iterative inversion procedure based on (a rearrangement of) Parker’s (1973) formula for rapid calculation of the gravity anomaly caused by an uneven layer; the algorithm proved effective in practice (Sprenke and Kanasewich, 1982).

3D joint inversion of gravity-gradient and borehole gravity data
Exploration Geophysics, 2017Borehole gravity is increasingly used in mineral exploration due to the advent of slim-hole gravimeters. Given the full-tensor gradiometry data available nowadays, joint inversion of surface and borehole data is a logical next step. Here, we base our inversions on cokriging, which is a geostatistical method of estimation where the error variance is ...

Joint Gravity and Gravity Gradient Inversion for Subsurface Object Detection
IEEE Geoscience and Remote Sensing Letters, 2013A novel approach of joint gravity and gravity gradient inversion is presented for passive subsurface object detection in this letter. Gravity and gravity gradient anomalies induced by an object can be measured and inversed to estimate the mass, orientation, and distance of the object.

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

Memory-efficient implementation of gravity inversion
GEOPHYSICSThe distribution of density plays a crucial role in interpreting subsurface geologic structures for resource exploration and deep-structure research. However, conventional gravity inversion often involves storing a dense, large sensitivity matrix, demanding significant computational resources.
