  • Determination of Soil Activity in Kenyan Soils from Spectroscopy 
    Kariuki, Patrick C.; Woldai, T.; van der Meer, D. (2002)
    Soil activity is a term generally applied to the ability of a soil to take in and dispose water under changing moisture conditions. It is due to presence of clay minerals with a net negative charge to neutralise which, ...
  • Effectiveness of spectroscopy in identification of swelling indicator clay minerals 
    Kariuki, Patrick C.; Woldai, T.; van der Meer, D. (Taylor & Francis, 2004)
    Swelling soils are a major geological hazard worldwide and their identification is a major concern. Swelling is due to the presence of clay minerals with a potential to accommodate water within their crystal structure. ...
  • The Role of Remote Sensing in Mapping Swelling Soils 
    Kariuki, Patrick C.; Woldai, T.; van der Meer, F. (ARSRIN, 2004-09)
    The use of satellite images during the early stages of mineral exploration has been very successful in pointing out the presence of minerals such as smectites and kaolinite important in the identification of hydrothermal ...
