Effects Of Rainfall Variability On Farming Activities In Machakos Sub County, Kenya

ABSTRACT Varying climatic conditions with increased uncertainty mainly in rainfall and temperature are salient features in marginal areas globally, adversely affecting farming activities particularly in Africa. Kenya experiences variations of annual rainfall with considerable uncertainty. These variations ranging from below 500mm to above 2000mm annually, cause droughts and floods respectively, affecting farming activities and yields. This study focused on Machakos sub County, a semi arid are...

Palynological Analysis Of The St-5 And St -6 Wells, Offshore Tano Basin, South Western Ghana: Implications For Stratigraphy And Paleoenvironment

ABSTRACT Miospores and dinoflagellates recovered from sediments from the ST – 5 and ST – 6 wells, offshore Tano Basin, Western Ghana were studied in order to determine their ages, establish palynostratigraphy and determine environments of deposition. Based on First Appearance Datum (FAD) and (LAD) of marker palynomorphs, three (3) biozones were erected for miospores and dinoflagellates respectively. The characteristic taxa of each of the biozones have been discussed in detail. The three b...

Petrology And Geochemistry Of The K-Rich Granitoids In The Bole-Nangodi Belt Of The Paleoproterozoic Birimian Terrane Of Ghana

ABSTRACT The Paleoproterozoic Birimian province of Ghana is made up basically of parallel and equally spaced NE-SW trending greenstone belts (with the exception of one which trends N-S), one of which is the Bole-Nangodi belt which outcrops in the northern parts of Ghana. These belts petrologically consists of metasedimentary and metavolcanic rocks, both of which are intruded by granitoids of various ages. These granitoids can broadly be grouped into four; the Cape Coast, Winneba, Dixcove and ...

Palynology, Palynofacies And Hydrocarbon Potential Of Cretaceous Sediments In The Offshore Tano Basin

ABSTRACT Data from HD-1 well, offshore Tano Basin was subjected to optical and organic geochemical analysis to reveal the palynostratigraphy, palaeoenvironments and hydrocarbon potential of the said well. Organic geochemical studies of Total Organic Carbon and Rock-Eval pyrolysis analysis as well as the microscopic investigation of the 44 slides of ditch cuttings from a depth of 3370ft – 7290ft shows four (4) types of Palynofacies associations in the HD-1 well based on the sedimentary organ...

Hydrogeological And Hydrochemical Characterization of Crystalline Basement Rocks in The Upper District Region; The Talensi District

ABSTRACT Groundwater remains the single most important source of water in Talensi district for various purposes. Notwithstanding, little research on the quality and sustainability of the resource in the district exist. Hence a comprehensive quality assessment and a quantification of groundwater resources in the shallow unconfined aquifers of the Talensi district has been conducted using conventional graphical methods, mass balance and multivariate statistical techniques coupled with steady s...

Hydrogeochemistry And Isotopic Study Of The Origin Of Underground Mine Water At Golden Star Bogoso/Prestea Limited (New Century Mines

ABSTRACT Hydrogeochemical study of the origin of underground mine water at Golden Star Bogoso/ Prestea Limited (New Century Mines) was carried out to determine the geochemical processes controlling surface water, groundwater and underground mine water and to identify the source of recharge to the underground water in the mines; investigate the hydrochemical facies of groundwater in the various aquifers (gallaries), and identify the relationship between surface water and groundwater, and under...

PROVENANCE OF PALEOPROTEROZOIC BIRIMIAN METASEDIMENTARY ROCKS IN PARTS OF THE WA-LAWRA BELT, NORTHWESTERN GHANA

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 ...

STUDY OF THE ORIGIN OF SALINITY IN THE UNSATURATED SOIL ZONE USING CHLORIDE PROFILES AND STABLE ISOTOPE AT EKUMFI AKWAKROM AND EKUMFI ASOKWA MANKESSIM MUNICIPALITY OF THE CENTRAL REGION OF GH

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...
