Compact gravity inversion

GEOPHYSICS, 1983
We present a new criterion for the inversion of gravity data. The principle employed is to minimize the volume of the causative body, which is equivalent to maximizing its compactness. The anomalous density distribution is obtained using an iterative technique which is numerically stable and rapidly convergent.

Interactive gravity inversion

SEG Technical Program Expanded Abstracts 2005, 2005
We have developed a new approach for estimating the location and geometry of several density anomalies that give rise to a complex, interfering gravity field. The user interactively defines the assumed outline of the true gravity sources in terms of points and line segments, and the method estimates sources closest to the specified outline to achieve ...

Constraints in 3D gravity inversion

Geophysical Prospecting, 2001
A three‐dimensional (3D) inversion program is developed to interpret gravity data using a selection of constraints. This selection includes minimum distance, flatness, smoothness and compactness constraints, which can be combined using a Lagrangian formulation.

Generalized compact gravity inversion

GEOPHYSICS, 1994
Extending the compact gravity inversion technique by incorporating a priori information about the maximum compactness of the anomalous sources along several axes provides versatility. Thus, the method may also incorporate information about limits in the axes lengths or greater concentration of mass along one or more directions.

3‐D inversion of gravity data

SEG Technical Program Expanded Abstracts 1995, 1995
We present two methods for inverting surface gravity data to recover a 3-D distribution of density contrast. In the first method, we transform the gravity data into pseudomagnetic data via Poisson’s relation and carry out the inversion using a 3-D magnetic inversion algorithm.

Gravity inversion in Qinghai-Tibet Plateau

Physics and Chemistry of the Earth, Part A: Solid Earth and Geodesy, 2000
Abstract Due to its high elevation and high seismicity the Qinghai-Tibet plateau takes a primary position on the earth surface. The inaccessibility of the region makes geophysical studies difficult. Active seismic sounding is available along essentially one line crossing the eastern part of the plateau.

Gravity inversion using convexity constraint

GEOPHYSICS, 2000
We present a constraint which incorporates in the geophysical inverse problem a priori information about the source convexity. Two kinds of convexity are considered: directional convexity, defined as the attribute of a body being intersected at most at two points by a straight line with a fixed spatial orientation, and global convexity, defined as the ...
