Abstract Aeromagnetic and vertical electrical sounding around Ijano, southwestern Nigeria, was investigated for groundwater potential. dataset were acquired used to investigate the study area. Oasis Montaj, Microsoft Excel Arc GIS present results in maps, images profiles. In order map out geological structures of area, magnetic image enhancing filters applied total intensity using Geosoft (Oasi...

Abstract. Aeromagnetic exploration is an important method of geophysical exploration. We study the compensation towed bird system and establish interference model. Due to geomagnetic gradient changing greatly, considered in In this paper, we model field analyze influence on aeromagnetic results. Finally, apply ridge regression solve problem. verify feasibility through actual flight tests furthe...

Abstract The Sinai Peninsula is a subplate located between the African and Arabian plates. It an important in world; however, this region poorly understood because of shortage geophysical data. Thus, study focuses on built three-dimensional (3D) high-resolution forward model crustal thickness with new tectonic structural evaluation to understand area tectonically determine its lithospheric thic...

In order to refine the geological mapping and improve our knowledge of Tlemcen Mountains structure (northwestern Algeria), interpretation aeromagnetic data using several processing techniques allowed us map Paleozoic basement Rhar Roubane sedimentary cover constituted by formations Mesozoic Cenozoic age. Structurally, are formed structures (e.g., Sebdou Graben), separated three major transverse...

Abstract The renewed quest to boost Nigeria’s dwindling reserves through aggressive search for oil and gas deposits in Cretaceous sedimentary basins has re-ignited the need re-evaluate hydrocarbon potentials of Dahomey Basin. Aeromagnetic data are a low-cost geophysical tool deployed mapping regional basement structures determination depths thickness frontier basin exploration. In this study, h...

S U M M A R Y Combining CHAMP satellite magnetic measurements with aeromagnetic and marine magnetic data, the global geomagnetic field has now been modelled to spherical harmonic degree 720. An important tool in field modelling is the geomagnetic power spectrum. It allows the comparison of field models estimated from different data sets and can be used to identify noise levels and systematic er...

Communities in North Africa and the Middle East are suffering from a lack of water supplies. In Egypt, this problem will be severe due to expected shortage River Nile supply. Therefore, looking for investigating groundwater aquifers target. The current study is an attempt investigate Wadi El Assiuti area’s deep aquifer, which has been identified as potential development, establishing new commun...

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what is commonly called 'worm analysis', i.e., the traditional visual inspection of gravity and aeromagnetic data in order to detect shallow faults, lineaments, contacts etc. More importantly, with the use of an appropriate wavelet, defined by the physics of the problem, informati...

Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mo...
