Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Nose Structure Delineation of Bouguer Anomaly as the Interpretation Basis of Probable Hydrocarbon Traps: A Case Study on the Mainland Area of Northwest Java Basin

Indonesian Journal on Geoscience, 2014
DOI: 10.17014/ijog.v7i3.144Two important aspects in the exploration of oil and gas are technology and exploration concepts, but the use of technology is not always suitable for areas with geological conditions covered by young volcanic sediments or ...

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

The use of microgravity technique in archaeology: A case study from the St. Nicolas Church in Pukanec, Slovakia

Contributions to Geophysics and Geodesy, 2009
The  detection  of subsurface cavities,  such  as  crypts, cellars  and  tunnels,  in churches  and castles  belongs to successful applications of the employment of surface  gravity measurement techniques in archaeo-prospecting.

Extraction of lineaments and faults using gravity second horizontal derivative data obtained using Fourier transform

Геофизический журнал, 2018
Linear anomalies are important in the interpretation of gravity data because they indicate some important structural features. Gravity anomalies obtained from horizontal derivatives generally reflect lineaments and faults or compositional changes which ...

Automatic estimation of the regularization parameter in 2-D focusing gravity inversion: an application to the Safo manganese mine in northwest of Iran

, 2014
We investigate the use of Tikhonov regularization with the minimum support stabilizer for underdetermined 2-D inversion of gravity data. This stabilizer produces models with non-smooth properties which is useful for identifying geologic structures with ...

Upgraded map of Bouguer anomalies of Lithuania based on GIS techniques

Geodesy and Cartography, 2012
The presently used Bouguer anomaly map of Lithuania is based on gravity field mapping of 1958-1961. The constant density 2,30 g/cm3 between the Earth’s surface and reference level (sea level) was employed to calculate Bouguer anomalies. The digital model
