The ground water occurrence, movement and potential in basement rock terrain is controlled by geological structures like foliations, fault, shear, folds which are commonly referred as lineaments revealed that in migmatite terrane serve as conduit for migration have exhibited variable yields of groundwater movement, Major targets in groundwater exploration surveys in basement terrains occur in areas having foliation, weathering of considerable thickness and/or where fracturing and jointing. The investigation discovered two significant fracture type for the area, low yield and high yield, which run in the and NW-SE/NE-SW directions, foliation plane (NNE-SSW and E-W) (conduit) as well as a structurally controlled drainage pattern. Because their presence is structurally driven, groundwater exploration in the area should be centered along NW-SE and NNE-SSW directions (predominantly), high yield fracture is attenuated to metatexite migmatute and low yield mostly associated to diatexite trending NW-SE and NE-SW cross-cutting the foliation in the migmatite, The results reveal a good agreement between the trends of fractures derived from the surface manifestation and foliation for groundwater availability making high foliation indicate intense fracturing and thus, indicate areas of high groundwater potentiality. it may be concluded that the occurrence, distribution and movement of groundwater are influenced and impacted by geological structures which have a direct control as well as the lithology. This research has improved our understanding of groundwater occurrence and distribution
Key words: foliation, fracture, metatexite, diatexite, conduit, groundwater, migmatite
