The survey zone corresponds to the Sirba greenstone belt, one of Liptako Birimian Formations (LBF) Niger. Previous aeromagnetic and geochemical works reveal significant gold occurrences. present study integrates geophysical mapping these occurrences by electromagnetic induction on field. A multi-frequencies system 10 frequencies was used for depth subsurface investigation resistive anomalies. i...

The map depicts distribution bedrock...

Abstract We present a new magnetic compilation for Central Gondwana conformed to recent satellite model (LCS-1) with the help of an equivalent layer approach, resulting in consistent levels, corrections that have not previously been applied. Additionally, we use data its full spectral content, which helps include India, where high resolution aeromagnetic are publically available. As India is lo...

Geothermal energy resources have been established globally to be among the sustainable and environmentally harmless means of generation. Curie-point depths (CPD), temperature gradients, heat flow data over study area were computed using a spectral analysis method in order preliminary view geothermal implications (prospect) current area. Aeromagnetic acquired by Nigerian Geological Survey Agency...

Abstract The current study is mainly devoted to the integration, analysis, and interpretation of available geologic, remote sensing, potential field data (mainly magnetic) delineate subsurface geologic structural elements controlling western part Baranes, South Eastern Desert, Egypt, its relation southwestern desert regime. Additionally, detect mineralization zones for future mining plans in ar...

Evaluation, analysis and interpretation of aeromagnetic satellite imagery data acquired over the Nigeria confluence environs; Northcentral were carried out in order to characterise structural framework study area. Fourier domain digital filtering tools reduction magnetic equator (RTE) operations achieved enhance available data’s results. The geomagnetic field earth was removed from using IGRF- ...

The aeromagnetic data of Nkalagu and Abakaliki areas were interpreted using spectral analysis modeling to estimate depth the sedimentary thickness, nature intrusive, susceptibility values types minerals associated with them. total magnetic intensity was processed produce residual map which divided into 21 overlapping blocks. Each block subjected a program plot (SPP) developed MATLAB obtain dept...
