Sr and Nd analyses of Congo sediments and Kalahari duricrusts
We investigated red-beds, boulders of silcretes and calcretes exposed around the margins and in river systems of the Congo Basin. We analyzed trace elements, 87Sr/86Sr and 143Nd/144Nd of 21 samples, and performed dilute leaching experiments on 3 of these samples to determine the source provenance and potential to release Sr during weathering. These samples were analyzed by ICP-MS at the University of Cape Town (UCT) and Nelson Mandela University (NMU) in South Africa.
Coverage Scope: Regional (Continents, Oceans)
Geographic Location: Kalahari Plateau, Congo Basin, DRC, Botswana
