Geology And Occurrence of Groundwater In Ishieke Area, Southeastern Nigeria

ABSTRACT

 The study area is located in the Abakaliki formation of Asu-River group Lower Benue Trough. The area lies between latitude N060221 011to N060 281 011of the equator and longitude E0080 001 011 to E 0080 061 011of the Greenwich meridian. The study was carried out to ascertain the geology and the occurrence of groundwater in the area through detail geological field mappings geophysical investigation and pumping test. Field observations shows that the area is made up of two lithological unit. The shale unit and the limestone unit. Geologic field mapping reveals that Ishieke area is underlain by Abakaliki shale of Abakaliki formation, Asu-River limestone, siltstone and intrusions all belong to the Asu-River group southern Benue trough. The Albian Asu-River group consist of dark gray to blue indurated shale which covers the entire Abakaliki formation with limestone, lenses of sandstone, intrusive dolerite sill and pyroclastic.  The occurrence of groundwater in the Isieke area is locally distributed this was confirmed with geophysical investigations and well drilling. The ground water occur in fractured zones, which are mostly fractured shale and limestone which have been tectonically affected. The geophysical data acquired was interpreted with IPI2WIN software. The pumping test was done with 1HP pump (high head), the test was done for 180 minutes and quick recovery of about 75 minutes was recorded showing that the aquifer is prolific.
