Hydrogeological and Geophysical Study of Bosso Area of Minna, North-Central Nigeria

Abstract

The hydrogeological potential of Bosso area was carried out using a combination of geology, hydrogeological and geophysical methods. Detailed geological mapping of the area was carried out to determine the dominant rock type and fracture pattern in the area. The Static Water Level (SWL) in most hand-dug wells in the area was measured and the data obtained were picked for Vertical Electrical Soundings. The field mapping reveals that granites are the major rock type in the area followed by schist and gneiss respectively. The analysis of the vertical electrical sounding showed that the area is characterized by three geo-electric layers. The Rosette diagram and the radial geo-electrical sounding polygons show a fracture pattern of NE - SW and NW - SE direction. The vertical and lateral variation in the thickness of weathering of the rocks in the area favours groundwater exploration.
