Application of alteration minerals and thermal fluid geochemistry in geothermal conceptual modeling, case study of Olkaria geothermal field in Kenya
(University of NairobiGeology, 2012)The Olkaria geothermal field is located within the central sector of the Kenyan Rift Valley in Naivasha basin. It is a high-temperature geothermal system and is associated with late Quaternary rhyolite volcanism. The ... -
Groundwater quality in Samia area of Busia county, Western Kenya
(University of NairobiGeology, 2012)This study focuses on the groundwater quality in Samia area, western Kenya. It also investigates the aquifer types and their possible impacts on the water quality. The geology of the area comprises granite-greenstone ... -
Geophysical mapping of structures in Anza Basin, Northern Kenya
(University of NairobiGeology, 2012)The study area is located at the Anza basin. It lies between latitudes of 380 05/ E& 380 25/ E and longitudes of 20 00/ N & 20 21/ N and covered an area of 1,687.5 km2. The area is important due to its thick sedimentary ... -
Analysis of oil exploration plays in Anza Basin from a trap-type perspective
(University of NairobiGeology, 2012)The Anza basin is a sedimentary basin in North Eastern Kenya. The first wells in the Anza basin were drilled in 1976. Chevron and Esso drilled Anza-1 and Bahati-1 wells in the southern part of Anza Basin. Since then 11 ... -
Stratigraphic and structural interpretation of seismic sections in Lokichar Basin
(University of NairobiGeology, 2012)This research was carried out in Lokichar Basin located in Turkana County in Northwestern Kenya. The study area is within the Tertiary Rift Basin of the four sedimentary basins of Kenya which include Lamu, Anza, Mandera ... -
Structural and geological control of fluoride levels in groundwater and defluoridation in Elementaita, Nakuru county, Kenya
(University of NairobiGeology, 2011)The study assesses the influence of geology and geological structures such as faults, joints and fractures on elevated fluoride levels in groundwater around Elementaita area, Nakuru County, Kenya. It also documents ... -

(University of NairobiGeology, 2011)This project describes the analysis carried out in the Olobanita well-field, Nakuru county, Kenya, using geophysical surveys and geologic logs with an aim of investigating the geometry and lithology responsible for ... -
Pyroclastic rocks as a tool to evaluate geothermal systems in the Kenyan Rift valley
(University of NairobiGeology, 2011)Pyroclastic rocks when studied keenly would be a big boost to identifying the geothermal system of a targeted area and better still a geothermal prospecting tool in potential regions, even before other surface investigations ... -
Interpretation of structural controls of ground water flow using geophysical techniques in the region South of Lake Nakuru (Delamere-Enderit area)
(University of Nairobi, 2011)Water is one of the vital elements all over the world and due to several factors such as over exploitation, water resources are steadily decreasing. This study is therefore aimed at characterizing the nature of the shallow ... -
Effects of climate change and human activity on lake levels in the Kenyan rift (case study Naivasha)
