W-E

(ii) The northern domain located between 4[degrees]30'00"N and 7[degrees]30'00'N reveals four major directions (W-E, N-S, NE-SW, and NW-SE) of supposed faults.

The linear local peaks of HGM are trending in NE-SW, NW-SE, W-E, and N-S directions.

The geological boundaries are marked out in NE, East, and Southern part, respectively, with NE-SW, NNE-SSW, and W-E trends.

The output from the Euler method shows that there are many faults segments trending in W-E, N-S, NW-SE, NE-SW, and WNWESE directions.

They extend at the southern to the northern part of the area and follow W-E, N-S WNW-ESE, and NW-SE directions.

Among the 80 extracted lineaments, 37.50% correspond to the largest trends in the W-E direction, 12.50% striking in the N-S direction, 11.25% also corresponding to NW-SE, NESW, and ENE-WSW direction.

The major directions of minor lineament are W-E, N-S, and WNW-ESE.

Faults with N-S and W-E direction characterize the definitive stability of the Congo craton which would be associated with the Eburnean orogeny.

The minor faults in the southern part with W-E, NS, and WNW-ESE trending materialized the stability of this domain which is represented by the Ntem Complex.

The predominant W-E, N-S, NE-SW, ENE-WSW, and WNW-ESE fault directions prove that the regional stress field which affected the Base Complex in the Central Cameroon region is responsible for the reorientation of the former structures observed on the Ntem Complex or Congo craton [34].
