We introduce a novel approach to three-dimensional gravity inversion in the presence of sediment-basement interface with strong density contrast. This makes it possible incorporate known information about basement depth inversion. It also allows user determine depth-to-basement initial phase. One can then use this constrain final First, generates model based on 3D Cauchy-type integral represent...

Abstract A clean corrected complete Bouger anomaly would perform reasonable geological subsurface interpretation. As a part of the processing phase, terrain correction has significant influence. Since entangles vast area, it is not easy to fulfill with land survey. Our study aimed apply an SRTM DEM in addition survey data overcome satisfactory correction. We have applied calculate for outer zon...

Gravity research in the Rajabasa geothermal prospect area was conducted to determine geothermalreservoirs and faults as reservoir boundaries. The includes spectrum analysis separation of Bouguer anomaly obtain a residual anomaly, gradient using second vertical derivative (SVD) technique identify fault structures or lithological contact, 3D inversion modeling density distribution subsurface mode...

Abstract Greece is a country structured by land, several islands and sea. A regional gravity model of such demands the involvement types data in order to cover all its territory. In this paper, we present development combined surrounding area, integrating terrestrial, marine (shipborne altimetry-derived data) satellite (GOCE GRACE data). These kinds data, especially terrestrial ones, have passe...

Hyperextended margins are very heterogeneous along the entire length of margin, so definition tectonic domains made exclusively from 2D seismic sections presents serious limitations. In this work we present an approach 3D crustal-scale structure West Iberia margin (WIM) by modelling eight lithospheric sections, using seismic, wells and gravity data. The continuous nature data allowed us to prop...

Tam Ky - Phuoc Son area has great potential for gold mineral with 98 occurrences, but the evaluation of entire gold-mineralization is still very limited, while this considered as a basis planning, exploration, and mining. The paper uses an Artificial Intelligence model which name Random Forest to build predictive modeling perspectivity map prospect study area. 12 influencing factors are selecte...
