ABSTRACT The Dahomeyide suture zone marks continental amalgamation between the Paleoproterozoic West African Craton (WAC) and the Sahara Metacraton (SMC). This suture zone of the PanAfrican orogenic belt is encrusted by UHP/HP metamorphic rock bodies and associated ultramafic igneous plutonic rocks in SE Ghana through to Togo and Benin. The main identified rock types consist of mafic granulites (hornblende-garnet-pyroxene gneiss and pyroxenegarnet-hornblende gneiss), felsic gneiss, eclogite a...
The growing demand for potable water supply has been a major challenge in Ado-Ekiti, Southwestern Nigeria. Delivery of good quality water by the Ekiti State Water Board to individual consumers in the required quantity and under satisfactory pressure is suspect. Even in areas that are supposedly served by piped water, the supplies to homes are extra-ordinarily intermittent in flow. This inevitably undermines the confidence of consumers, resulting to complaints and possibly the use of water fro...
ABSTRACT Geological mapping and geochemical analysis of rock samples were made on pit rocks from Obuem Mining Concession found within the Birimian of Ashanti Belt of Ghana, in order to determine the nature of gold mineralisation. The study area consists of metavolcanics and metasediments with few intrusions of granitoids. Metasediments such as phyllites and schists as well as metavolcanics of andesitic and basaltic origin were sampled and analyzed for their major and trace element contents us...
ABSTRACT Accra has been experiencing periodic flooding that affects properties and lives. For instance on 41h and Sib June 1994, 8 persons lost their lives and 80 million cedis worth of properties belonging to Paloma Company were destroyed due the floods that occurred at that time. The government seeing the dangers involved. commissioned institutions such as Ministry of Works and Housing, Tourism and Country Planning and City Engineers to identify such areas and adopt measures that will ...
ABSTRACT The study adopted a pragmatist approach to assess farmers‟ vulnerability and adaptation to drought in three agro-ecological-locations in Ghana. It analysed the variations in precipitation deficits by using precipitation values for 1983-2014 period. It also assessed the variation in drought vulnerability, farmers‟ adaptation and barriers to drought adaptation. The cross-sectional survey design was utilised. A random sample of 326 farmers and six purposively selected lead farmers p...
ABSTRACT Ground magnetics and electromagnetic datasets were processed to interpret the subsurface geology and structure of the southwest of Ghana within the Tarkwain and Volcanics in the central part of the Ashanti belt. The study was aimed at mapping lithology, delineating structural lineaments and their trends as well as the trend of mineralization in the study areas. The data processing steps involved enhancement filters such as reduction to the pole, analytical signal, the first horizonta...
ABSTRACT The Akwapim Fault zone is one of the two major fault zones in the southeastern part of Ghana. Its junction with the Coastal Boundary Fault happens to be epicenter for most of the earthquakes that occur in Ghana. The earliest work done in this region was by the Gold Coast Geological Survey on a regional scale in mapping the area to determine the geological structures. With most of geological deformational features being inferred, it is prudent to carry out more research to identify mo...
ABSTRACT Agbaja Ironstone Formation of the Lokoja district, Central Nigeria occurs within the Upper Cretaceous sedimentary sequences of the NW-SE trending Nupe Basin. Three lithostratigraphic units were delineated; Lokoja Sandstone (the oldest), Patti Formation and Agbaja Ironstone Formation. Lokoja Sandstone rests unconformably on the basement complex and grades from conglomerate to arkosic sandstone. Patti Formation consists of intercalations of sandstone, siltstone and carbonaceous mudsto...
ABSTRACT Particulate Matter (PM) are suspended solid and liquid particles in the atmosphere, classified into coarse (PM10, 2.5 to 10µm) and fine (PM2.5 2.5 µm) and irregular in shape with very few being regular and fine (Fe>Al>Na>Mg>Si>Zn>Cu>Mo>Mn>Ba>Ti>Pb>Ni>La. The IA showed highest average concentration of all elements in the PM10 except Ba, which was highest in TA. The elemental composition agreed with the mineralogical data as revealed by the PCA. Factor 1 was loaded with Al, Si, Ca, ...
This study was conceptualised out of a need to help stem the continuous rising incidences of failed and abandoned wells in the study area. This situation is attributable to inadequate understanding of the hydrogeological and structural disposition of the area. The study area is underlain by crystalline rocks belonging to the Basement complex of Nigeria. These rocks comprise of Schist, Gneiss, Quartzite and Granite with minor occurrences of alluvial deposits. Analysis and interpretation of the...
