Abstract

50 Vertical Electrical Soundings (VES) and 180 Horizontal Soundings (HS) were carried out in the Pan-African geological setting of Central Africa in order to explain the behavior of the electrical signal in this context. Results highlight the presence of very high resistivity values in some locations (greater than 300 kΩm) and large amplitude of resistivity dropping in other sites. Further geological and tectonic investigation shows that higher resistivity values match with the gneiss-granitic nature of the substratum while lower values are due to the presence of faults, shears, and alteration of ultramafic rocks as well as the presence of sedimentary rocks and deformation phases in the region. Those low-resistivity areas can be exploited in the groundwater exploration processing.
