Abstract:
We explored Precambrian crystalline zone conductivity from recent Electromagnetic data combined with geostatistics, in the southern part of Cameroon to guide future hydrologic research. With the Magnetotelluric (MT) data, experimental semivariogram was constructed to analyse spatial variability of the resistivity in this area. Among several models, the Gaussian semivariogram model was used to compute the resistivity map of the studied area. An analysis of these results shows that, the area is characterised by a wide margin of resistivity. The Correlation with some recent results from boreholes suggested that, conductive zones can guide the further exploration research of ground water reservoirs in this area. The inverse operation allows us to estimate the depth of these anomalies.
