ABSTRACT Prospective evaluation of “XY” field in southwestern offshore Niger Delta was carried out with a view to delineate the structural and stratigraphic traps present in the study area. The research methodology involved horizon and fault mapping to produce subsurface structural maps. Attributes used to analyze the field under study includes: Variance time slice which was used to illuminates the main fault structure on the field and aid as guide to proper mapping. Similarly, this was ...
ABSTRACT Alaago-Alapoti area constitutes part of the Eestern Dahomey Basin of South-Western Nigeria and it is characterized by different formations. Samples were collected from this area and were subjected to the laboratory for test. Nine smaples were collected from Alaago-Alapo area, five hand-dug wells and four boreholes sampled and investigated in the persent study. This study characterises the physicchemical quality of ground water obtained from the hang-dug wells and boreholes. To get a...
ABSTRACT Laterites are soils that formed from the weathering of the basement complex and are rich in secondary oxides of Iron and Aluminum. It‟s red colouration is due to it‟s high iron content. Laterites are mostly found in Tropical regions which are characterized by distinct dry and wet seasons. Laterites are mainly used in the construction ofroads either as a subgrade or as a sub-base material. Geotechnical evaluation is one of the effective means of detecting and solving pre and post...
ABSTRACT Geo-electrical resistivity techniques are increasingly being applied in addressing a wide range of hydrological, environmental, and geotechnical problems. This is due to their effectiveness in near-surface characterization. Seven (7) vertical electrical soundings (VES) was integrated with 2-D geo-electrical resistivity in three locations and three traverses to characterize the near-surface and subsurface and also delineate the underlying aquifer properties in the sedimentary terrain...
ABSTRACT Electrical resistivity method involving the2-D surveying was carried out within the sedimentary complexterrain of Alapoti Ogun State South Western Nigeria with a view of estimating the geo electric layer parameters (resistivity and thickness),to identify the aquifer types and evaluate the ground water potential and over burden protective capacity over the aquifer.
ABSTRACT The need to increase the agricultural outputs is the major concern of the farmers in Ado-OdoIlaro District. Therefore there is need to determine the physico-chemical and geochemical parameters of groundwater and surface water within this sedimentary terrain in order to ascertain the quality of groundwater for agricultural purposes. Thirty-three underground water samples were collected for the determination of physical and chemical parameters. Sodium Adsorption Ratio (SAR), Soluble S...
ABSTRACT The environment is being degraded on a daily basis as a result of human activities like auto traffic, mining and agriculture among others. This has made environmental assessment studies and monitoring a matter of global attention considering our growing population Studies have also revealed that adverse health are associated with the pollution of the ecosystem by heavy metals which are easily bio accumulative but not biodegradable. This project is aimed at assessing the level of met...
ABSTRACT This study is aimed at determining the suitability of laterite soil derived from granite-gneiss from the burrow pit along Km 4 Ologuneru-Eleyele Road as a subgrade or subbase material Three samples were collected at different height from a burrow pit in the study area and were subjected to soil tests such as natural moisture content, optimum moisture content, maximum dry density, specific gravity and Atterberg limit at its dry state. Engineering tests such as California bearing rati...
ABSTRACT The study area, Ijesha-Ijebu falls within the Nigeria sector of the Eastern Dahomey Basin. It lies within the contact zone between the south-western basement rocks and the Eastern Dahomey Basin. The principal objective of this project work is to deduce the depositional environment and identify the formations in the study area. The field and laboratory investigation were carried out during this project work. Nineteen (19) rock samples collected were described for its: grain texture, ...
ABSTRACT The Turonian Nkalagu Formation exposed at NIGERCEM (Nigerian Cement Company) within the Lower Benue Trough was studied in this work in order to determine and establish the lithostratigraphic successions and reconstruct the paleoenvironment of the deposition. Two major litho-facies were delineated. The first is matrix-supported bioclastic shell lag wackestone facies which account for about 70% of the carbonates. The second is a massive fossil-poor micritic limestone. However, using th...
ABSTRACT Shales from the Paleoproterozoic Birimian Supergroup in parts of the WaLawra Belt, Northwestern Ghana, were analyzed for their major and trace element contents using ICP-MS and ICP-AES with the main aim of establishing the geochemical characteristics of the shales and inferring their provenance. On the whole twenty-two (22) samples of the shale was collected for analysis. The studied shales were compared to Early Proterozoic crust (EPC) and Post Archean Australian Shales (PAAS), and ...
ABSTRACT This research was carried out to investigate the origin of salinity in the unsaturated soil zone with emphasis on chloride profile and stale isotopes in the Ekumfi Akwakrom and Ekumfi Asokwa in Mankessim Municipality of the Central Region of Ghana, which has been reported to have high saline groundwaters. A total of 159 samples were analysed, which comprises: fifty – six (56) rainwater samples, fifty – three (53) soil from the unsaturated zone, two (2) groundwaters, forty – two...
ABSTRACT The Paboase deposit located in the Chirano gold district is hosted in Paleoproterozoic rocks within the Sefwi-Bibiani volcanic belt of the Birimian, which has been regionally metamorphosed to greenschist facies. Gold mineralization at Paboase is largely hosted by albite-pyrite-carbonate altered mafic and porphyry intrusive rocks rather than Birimian sedimentary rocks and graphitic shear zones which are well known style of mineralization in southwest Ghana. Multi-element geochemistry ...
ABSTARCT A seismological and geological investigation for earthquake hazard in the Greater Accra Metropolitan Area was undertaken. The research was aimed at employing a mathematical model to estimate the seismic stress for the study area by generating a complete, unified and harmonized earthquake catalogue spanning 1615 to 2012. Seismic events were sourced from Leydecker, G. and P. Amponsah, (1986), Ambraseys and Adams, (1986), Amponsah (2008), Geological Survey Department, Accra, Ghana, Ampo...
ABSTRACT Assessment of viability of an ore deposit depends on the accurate estimation of the quantity and quality of the commodity, which is a function of the sample data quality. SAMEVA Limited, a fully owned Ghanaian company, wants to acquire Kojina Gold deposit as an investment opportunity in the gold industry of Ghana. The decision to invest in the mining industry comes with huge capital requirement and the associated risks are very high. The major objectives with regards to evaluating th...
