title: Uranium-thorium levels in the sediments of the Kubanni River in Nigeria.
abstract: U-Th levels of the Kubanni River sediments in the Nigerian Basement Complex have been determined and shown to be enriched with mean values of 9.06+/-2.66 and 21.44+/-4.12 (ppm) respectively. The probable contributory factors are either phosphate fertilisers used on the neighbouring farms or low aeolian depositions from the NE trade winds blowing from the Sahara desert across the Northern Nigeria Savannah region. The other major contributing factor is the annual weathering of the basement granites. This work revealed more clustering of our data sets below the igneous line as proposed by other authors.
