Contribution to the Mineralogical Study Using Electrical Tomography in Foum Tizza Area, Eastern Anti-Atlas, Morocco

Abstract

In the Foum Tizza area of Taghbalt, which is located in the Paleozoic cover of the eastern Anti-Atlas of Morocco, a mineralogical study has been done by electrical tomography, with the objective of drawing up a plan of action for future mineral exploitation. To achieve this objective, we first performed a geological assessment of the study area, followed by a geophysical investigation using electric resistivity and induced polarization surveys. The arrangement used is dipole-dipole and the processing of the geophysical data before and after inversion was carried out using Res2Dinv software. After defining the structural contacts and locating the metallogenic anomalies in relation to the field stratigraphy, the faults are mineralized and loaded in barite (BaSO4) and lead sulfide (PbS) with veins orientation WNW-ESE to E-W.

Geotechnical Prospects and Electrical Tomography to Study Slope Instability in the Rif Alboran Sea Shoreline on The Mediterranean By-Road (Northern Morocco)

“…It is based on the measurement of apparent electrical resistivity of the subsurface along a set of straight cables connected to a defined number of electrodes, for a large number of positions and spacing of the electrical current injection electrodes and those for the calculation of the potential difference. This geophysical prospecting technique allows for a geological and geometric description of the subsurface based on the resistivity contrast of the formations (Günther & Rücker 2012;Zhou 2018;Sassioui et al 2022).…”
