SPACETIME OR QUANTUM PARTICLES: THE ONTOLOGY OF QUANTUM GRAVITY? [PDF]

open access: yes, 1996
The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory

Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data [PDF]

open access: yes, 2013
The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica from a collage of crustal blocks in West Antarctica.

Predicting Depth of Mineral Deposit using Gravity-Density Downward Correlation by Fourier Transform

open access: yesГеофизический журнал, 2016
Residual gravity anomalies are the superposition of effects originating from several interfaces in the subsurface. In downward projection of the anomalies for the determination of the depth of the particular substructure which accounts for the bulk of ...

Prediction of gravity anomalies for geophysical exploration [PDF]

open access: yes, 2010
Interpretation of gravity anomalies (determined on the earth’s surface) reveals information on mineral resources beneath the earth. The density of gravity stations (where gravity anomalies are determined) is critical to the successful interpretation of ...

Comparison of Gravity Anomalies from Recent Global Geopotential Models with Terrestrial Gravity and Airborne Gravity over Johor Region [PDF]

open access: yes, 2021
Gravity anomalies can yield an indirect but extremely useful picture of lateral changes in rock composition and structural patterns especially for rapid development area such as Johor region.

A method for extracting the preseismic gravity anomalies over the Tibetan Plateau based on the maximum shear strain using GRACE data

open access: yesEarth and Planetary Physics
The occurrence of earthquakes is closely related to the crustal geotectonic movement and the migration of mass, which consequently cause changes in gravity.

Mare Orientale Gravity Anomaly [PDF]

open access: yesNature, 1970
SJOGREN has reported that there is an annular negative gravity anomaly surrounding a small positive anomaly over the central basin of Mare Orientale (paper given at the NATO Advanced Study Institute on the Moon and Planets, Newcastle, April 1970). I should like to point out that outside this negative ring, there is a positive ring and perhaps further ...

On the interpolation of high-frequency gravity field signals in mountainous areas

open access: yesContributions to Geophysics and Geodesy, 2013
The paper presents a comparison among different techniques in interpolating high-frequency gravity field signals in mountainous areas. A gap of 1◦ ×1◦ has been artificially created within the free-air gravity anomalies data set for Austria.

What controls gravity anomalies in subduction zones? The relationship with plate motion and slab geometry

open access: yesProgress in Earth and Planetary Science
Subduction zones have characteristic patterns of free-air gravity anomalies: high in the arc, low in the trench, and gently high in the outer rise. In order to understand which parameters control the formation of the gravity anomalies, we investigate the

Gravity analyses for the crustal structure and subglacial geology of West Antarctica, particularly beneath Thwaites Glacier [PDF]

open access: yes, 2008
textThe West Antarctic Ice Sheet (WAIS) is mostly grounded in broad, deep basins (down to 2.5 km below sea level) that are stretched between five crustal blocks. The geometry of the bedrock, being mostly below sea level, induces a fundamental instability
