ABSTRACT: To
achieve the current study, geoelectrical surveys along six (06) profiles of 4
km long in a 100 m × 200 m grid defined according to the triangulation
principle in the Tindikala-Boutou (Eastern-Cameroon) area along
the Kadey River have
been made through electrical sounding and profiling following Schlumberger
array. The instrument is the resistive meter Syscal Junior 48 (IRIS
Instrument). The data have been processed and modelled with Res2Dinv and Winsev
softwares, and then interpolated with Surfer software. Investigation method
used is the Direct Current (DC) method. Interpretations and analyses of results
from the investigation method highlight weak zones or conductive
discontinuities. The latter has been identified as shear zones within granitic
structures of the Precambrian basement, according to the geologic and tectonic
background of the area. The structural trend of these shear zones is E-W
approximately. The mineralization characterized by conductive zones proves the
presence of clay minerals disseminated in weathered quartz vein, which cross
the shear zones. The intense activities of gold washers encountered in the
studied area are able to attest the presence of clay minerals concentrations.
