Bouguer gravity anomalies (BGA) play an important role in exploration of mineral resources. Allowing the delineation large geological structures, BGA participate into discovery deposits. However, Kiri uplift region where several oil seeps have been recognized faces sparse coverage data due to difficult conditions acquisition on field. This situation increases non-uniqueness and nonlinearity pro...

using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...

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...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...

Gravity survey is one of the passive geophysical techniques commonly used to delineate geological formations, especially in determining basement rock and overlying deposit. Geologically, study area made up thick quaternary alluvium deposited on top older rock. The Muda River basin constitutes, approximately, more than 300 m unknown type. Previous studies, including drilling geo-electrical resis...

We conduct a gravity study of the lithosphere beneath three large sedimentary basins in southeastern South America: Paraná, Chaco-Paraná, and Pantanal. compile massive database estimate free-air Bouguer anomalies, resulting novel complete anomaly map for area. To discern influence crustal loads with known lithologies, including sediments, basalts, topography variations Moho discontinuity, we ca...

The analytical signal method and its derivatives can be explicitly calculated assessed for analyzing estimating the boundary of geological structures, such as faults or dikes, from potential field anomalies. Gravity east Qeshm Island north coast Sarkhun to Latidan in SE Iran has been measured one-kilometer regular network. regional anomaly effects are deducted Bouguer anomaly, where it get resi...
