This paper focuses on the incised Modder River at Erfkroon, Free State, located ∼ 1480 km (river distance) inland from the Atlantic Ocean. At Erfkroon...

The Riverton Formation sediments may be the time equivalents of lithologically similar alluvial successions deposited along the Modder River ( Tooth et al., 2013 ). In the Free State, the Quaternary...

Alluvial successions and associated palaeosols of the Modder River near Erfkroon, Free State, have provided a rich record of climatic fluctuations...

..., although there are not enough dated horizons to get a sense of accumulation rates. At a second Florisian fossil site of Erfkoon (site 71) ( Churchill et al., 2000 ), there is an overbank alluvial-palaeosol sequence associated with the Modder River that contains a three phase record of shifting...

... may show evidence of secondary (hydrothermal?) leaching of the rock mass with little to no biotite present. The Twakputs Gneiss occurs as a major rock unit in the lower Orange River region of the Northern Cape and in south-eastern Namibia. Good, accessible exposures of the Twakputs Gneiss can...

Luminescence dating of overbank deposits from the Modder River, central South Africa, shows a millennial scale pattern of flood variability from 43 to 19 ka ( Lyons et al., 2014 ). Lunette sand deposition took place between 52 to 46 ka...
