Clay Minerals Channels Identification in the Tindikala-Boutou Area (Eastern-Cameroon) along the Kadey River Using Direct Current (DC) Method

“…This curves' narrowing prove an inner to outer variation of geological structures along the N-S trend. Central structures materialize decayed rocks, accumulation or infiltration structures [11] [22]. They show up the presence of weakness zones in the central part of the study area [11] [22].…”

“…They are bounded top and down by more resistive structures. This structural geoelectrical morphology characterizes an accumulation zone of weathered structures or a fluids' infiltration zone [22] [23]. Meanwhile around 630 m and 450 m along profiles L4 and L5 respectively, an involvement of deep resistive materials on surface characterized by conic domes (Figures 5(a)-(b)) is observed.…”

“…Central structures materialize decayed rocks, accumulation or infiltration structures [11] [22]. They show up the presence of weakness zones in the central part of the study area [11] [22]. Otherwise resistive structures bounding these zones characterize fresh granitic formations [25].…”

“…These figures reveal an approximate investigation depth of 128 m for each profile. This depth corresponds to the maximum cable length (AB = 600 m) according to x l position along a profile [16] [22].…”

“…The electrical responses of these profiles (L2 and L3) look like resistive bedded layers (Rho > 3000 Ω•m) in the eastern side (2500 < x l < 3800 m and x l > 3000 m). Effects of these layers go downward to deep structures and they are evidences of fresh granitic structures which sometimes outcrop [22] [23]. The bedding and the resistance of layers disappear at the west; and a weakness, an accumulation or infiltrations' zone sets itself progressively.…”
