Pattern, age, and origin of structural features within the Ozark plateau and the relationship to ore deposits [PDF]

Topography and gravity anomaly images for the continental United States were constructed. Evidence was found based on gravity, remote sensing data, the presence, trend, and character of fractures, and on rock type data, for a Precambrian rift through ...

EVALUATION OF GRAVITY DATA IN THE KIFL OIL FIELD AND ADJACENT AREAS, SOUTH OF IRAQ

Iraqi Geological Journal, 2017
The study area located in southern part of Iraq, it covers about 4009 Km². The data used in this research consists of Bouguer anomalies (Regional and Residual anomalies) with scale of 1: 250 000. These data are mosaicked and clipped for the area

Crustal structure beneath Cameroon from EGM2008

Geodesy and Geodynamics, 2014
We used the Earth Gravitational Model (EGM2008) data sets to analyze the regional gravity anomalies and to study the underground structures in Cameroon. We first created a high-resolution Free-Air anomaly database, then corrected the gravity field of the

Image processing applied to gravity and topography data covering the continental United States [PDF]

The applicability of fairly standard image processing techniques to processing and analyzing large geologic data sets in addressed. Image filtering techniques were used to interpolate between gravity station locations to produce a regularly spaced data ...

Morphology and tectonics of the Mid-Atlantic Ridge, 7°–12°S

, 2003
We present swath bathymetric, gravity, and magnetic data from the Mid-Atlantic Ridge between the Ascension and the Bode Verde fracture zones, where significant ridge–hot spot interaction has been inferred.

Gravity pattern in southeast margin of Tibetan Plateau and its implications to tectonics and large earthquakes

Earth and Planetary Physics, 2019
There are many active faults in the southeast margin of Tibetan Plateau, where three large active faults zones, the Longmenshan, Xianshuihe and Anninghe, merge to form a "Y" shape. Strong crustal deformation and a complicated fault distribution accompany

Continental Hotspots Tracks From an Analysis of GOCE Gravity Gradients Data

Geochemistry, Geophysics, Geosystems
This study aims to detect residual thermal anomalies along the path of a hotspot beneath the continental lithosphere using gradiometry data. We calculate perturbations in gravity vectors and gradients by employing a simple thermal anomaly model.

Application of different edge detection methods for faults identification in Anza Basin, Kenya

Terrestrial, Atmospheric and Oceanic Sciences
The shape of gravity anomalies changes due to the disruption of geological bodies’ continuity by fault structures, and their planar contour line characteristics are an important basis for dividing fault structures.

Properties of the lithosphere and asthenosphere deduced from geoid observations [PDF]

Data from the GEOS-3 and SEASAT Satellites provided a very accurate geoid map over the oceans. Broad bathymetric features in the oceans such as oceanic swells and plateaus are fully compensated.
