GCH_gravinv: A MATLAB-based program for inverting gravity anomalies over sedimentary basins
Computational Geosciences, 2018This paper presents a Matlab-based program GCH_gravinv including an easy-to-use graphical user interface (GUI) for determining the depth to the basement of a sedimentary basin derived from inverting its gravity anomalies by an iterative procedure.

Forward modeling of gravity anomalies based on cell mergence and parallel computing
Computational Geosciences, 2018Forward modeling is a requisite for many geophysical applications; for instance, forward modeling is used to compute the gravity anomalies in local- or regional-scale geological models. In this study, we develop a simple and efficient approach for the 3D

Preliminary Investigation of Gravity Anomalies
Nature, 1950BECAUSE of similarity in methods of observation and reduction, it is possible to combine the gravity data of the United States Coast and Geodetic Survey and the Department of Mines and Resources of the Dominion of Canada in large-scale gravity investigations. The combined data include gravity observations extending from lat. 24° N. to 67° N.

Review of Scientific Instruments, 1957
An instrument that will simulate the anomalous gravity effects of a subsurface body, having a density differing from that of its surroundings, is described. The device makes use of the similarity between the gravity equation and Lambert's cosine θ law, and enables the geophysicist to synthesize the anomaly producing body in a time much shorter than ...

Doppler radio tracking of the Pioneer Venus orbiter has provided gravity measures over a significant portion of Venus. Feature resolution is approximately 300–1000 km within an area extending from 10°S to 40°N latitude and from 70°W to 130°E longitude (≈200°).

Gravity anomalies in Northwestern Canada
Bulletin géodésique, 1948Free air, Bouguer, and isostatic anomalies are listed in a table of principal facts for 23 stations established by the Dominion Observatory in the area between latitudes 55 and 70 degrees, bounded on the east by Hudson Bay and on the west by Athabaska, Slave, and Mackenzie rivers.

SEG Technical Program Expanded Abstracts 1989, 1989
Gravity data observations and compilations of Mexico, Central America and South America have resulted in Freeair, Eouguer, Isostatic and residual gravity anomaly maps. Most of these data in Mexico and Central America have been used for the southern portion of the recently published DNAG Gravity Anomaly Map of North America and the Gravity Anomaly Map ...
