Lineament Extraction using Gravity Data in the Citarum Watershed

open access: yesIndonesian Journal of Geography, 2021
Lineament is one of the most important features showing subsurface elements or structural weakness such as faults. This study aims to identify subsurface lineament patterns using automatic lineament in Citarum watershed with gravity data.

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 ...

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.

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.

Gravity Studies at Cerro Machín Volcano, Colombia

open access: yesBoletín Geológico, 2022
A gravimetric study was performed at the Cerro Machin volcano (4° 29’ N, 75° 22’ W), Tolima Department, Colombia,  to obtain a density distribution of the volcanic edifice and its basement. This study was divided into three main sections.

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

open access: yesGeophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

The Comparison of Magpick Anomaly Contours toward Bouguer Anomaly Reduction

open access: yesThe Indonesian Journal of Computer Science, 2023
The subsurface structures model can be made by various methods, one of which is the gravity method. The basis of gravity modeling is the difference in density of materials. This can result in gravitational anomalies. Overall gravitational anomalies are known as bouguer anomalies.
