    HYDROGEOPHYSICAL APPRAISAL OF RISHA, PART OF AKWANGA SHEET 209NE, NORTH CENTRAL NIGERIA
    (Department of Geology and Mining, Nasarawa State University Keffi, 2017-11-18) Jatau, B.S.; Tanko, I.Y.; Usman, O.H.; Yakubu, M.E.; Ayanninuola, O.S.
    Ageological traverse was undertaken in Risha, part of Akwanga Sheet 209NE North-Central Nigeria to appraise the rock types and their structural patterns that might enhance prospect for water. The geological traversing revealed basically three rock types which include schistose-gneiss, granite-gneiss and pegmatite (as veins and/or dykes) with their main structural pattern trending mostly NW-SE. Twenty three (23) Vertical Electrical Resistivity Soundings (VES) were carried out in the area using the Campus 0? .vega digital resistivity meter. This is in order to study the subsurface geological layers with a view to deterrrT
