| dc.description.abstract | The electrical resistivity tomography (ERT) and the ground penetration radar (GPR) techniques, were employed to characterize the possible lithostratigraphy units at the Kyereyiase clay deposit, in the Atwima Nwabiagya South District of the Ashanti Region of Ghana. The electrical resistivity method was used to measure the distribution of the resistivity beneath the subsurface thereby providing information about the surface geology. This helped in the mapping of the various lithological units in the study area. The GPR is a non-destructive method that uses electromagnetic radiation in the microwave band of the radio spectrum and detects the reflected signals from subsurface structures at a receiver antenna. This helped in the delineation of the lithological units in the area as well as the depth of the water table. From these results, three main lithological units namely, 5 m thick near surface clay/sandy layer, 20 to 30 m thick weathered granitoids both of which form the saprolite layer and the granitoids bedrock. The water table depth was mapped to ranges from 16 to 20 m. The particle size distribution analysis of soil samples from the area showed that the soil consists averagely of 2 to 24% clay, 8 to 34 % silt, 41 to 86% sand and 1 to 4% gravel. . Similar near surface investigations methods conducted within the study area by the Building and road research Institute (BRRI), under the Council for scientific and industrial research, as well as Ghana geological survey, and other similar research methods of exploring for clay as a subsurface resources, within the Asia and the north America has proving to be very successful for its economical viabilityness. | en_US |
