Abstract

Quaternary sedimentation in the Moshaweng dry valley of southeastern Botswana is evaluated on the basis of geomorphological evolution and sedimentological analyses. Stratigraphic evidence reveals an upper surface containing abundant sil-calcrete, an intermediate surface in which sil-calcrete underlies nodular calcrete and lower surface in which sil-calcrete and nodular calcrete are interbedded. This subdivision is reflected in the geochemical composition of the sediments. The AA. aim to enhance palaeoenvironmental information and provide tentative dating relating to valley formation
