Appraising the Structural Geology of Kakuri Sheet 144: Implications for the Tectonic Evolution of the Basement Complex

Abstract

The appraisal of the structural geology of Kakuri Sheet 144 using integrated analyses of remotely sensed lineaments, aeromagnetic anomaly, micro and macro structures show a tectonic framework expressed by a mainly NW - SE ductile vertically dipping foliation of transpressed tectono-metamorphic possibly pre-Pan African (S1) trend which has been overprinted by a set of NE - SW (L2) fracture system cut obliquely by an E-W (L3) sinistral shearing with a dextral sense. Magmatic activity might have exploited these north-easterly fracture systems which are consistent with the regionally deep seated north-easterly fault systems that define the limits of the schist belts, the younger granites and Benue Trough.
