Gravity data on the Central Pyrenees: a step forward to help a better understanding of the Pyrenean structures

open access: yesJournal of Maps, 2021
In this work, we present new Bouguer and residual Bouguer anomaly maps of the Central Pyrenees calculated from 3590 stations, of which 1141 are new observations acquired from surveys performed between 2018 and 2019.

The generalized Bouguer anomaly [PDF]

open access: yesEarth, Planets and Space, 2006
AbstractThis paper states on the new concept of the generalized Bouguer anomaly (GBA) that is defined upon the datum level of an arbitrary elevation. Discussions are particularly focused on how to realize the Bouguer anomaly that is free from the assumption of the Bouguer reduction densityρB, namely, theρB-free Bouguer anomaly, and on what is meant by ...

Bouguer anomaly map of New Zealand [PDF]

open access: yesNew Zealand Journal of Geology and Geophysics, 1958
Summary The Bouguer map of New Zealand exhibits two major negative gravity anomalies. The Rangitikei‐Waiapu Anomaly, which intersects tne axial ranges of the North Island, indicates a crustal downwarp which is not in isostatic equilibrium.

New Bouguer Gravity Maps of Venezuela: Representation and Analysis of Free-Air and Bouguer Anomalies with Emphasis on Spectral Analyses and Elastic Thickness

open access: yesInternational Journal of Geophysics, 2012
A new gravity data compilation for Venezuela was processed and homogenized. Gravity was measured in reference to the International Gravity Standardization Net 1971, and the complete Bouguer anomaly was calculated by using the Geodetic Reference System ...

Analysing the enhancement edges of the Bouguer gravity anomaly map using sunshading method (area of the Tangier-Tetuan, Morocco)

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
Sunshading is a powerful tool for the enhancement of edges in images. Given the azimuth and elevation of a source of illumination, it calculates the reflectance from a surface which is composed of the data to be interpreted.
