    Geological and geo-electrical investigation of diorite deposits in parts of Southern Benue Trough, Nigeria
    (Federal University of Technology, Owerri, 2017-01) Okoli, Stella Chigozie
    Diorite deposit investigation in Lokpaukwu and environs in Abia State, southern Nigeria has been carried out in Amaubiri, Umuneochi and Obiagu Lekwesi. The aim of the study is to determine the subsurface deposit and downward trend of the diorite deposit through variations in resistivity values. Thirty Eight (38) vertical electrical sounding (VES) was acquired withing the study area using schlumberger Array configuration. Data acquired were processed and interpreted using resistivity software. 3 geo-electric layers in Amaubiri, 4 layers in Obiagu Lekwesi and 4 to 5 layers in Umuneochi Lokpaukwu Area was deduced. Mean density were done to estimate total reserve in these areas to value the quantity in those areas using Archimedes principles. Samples were viewed under microscope to confirm the rock type in the areas. The variation in resistivity values show possibilities of the outcrop occurrences at shallow depths. The estimated reserve in Amaubiri is expected to be more than Lekwesi and Umuneochi. The use of electrical resistivity has proven useful evaluation of the quantity and downward trend of diorite rock in these areas.
