Southernmost Africa, with extensive upland geomorphic surfaces, deep canyons, and numerous faults, has long interested geoscientists. A paucity of dates and low rates of background seismicity make it challenging to quantify the pace of landscape change and determine the likelihood and timing of fault movement that could raise and lower parts of the landscape and create associated geohazards. To infer regional rates of denudation, we measured 10Be in river sediment samples and found that…

Constraining Plateau Uplift in Southern Africa by Combining Thermochronology, Sediment Flux, Topography, and Landscape Evolution Modeling
The uplift of the southern African Plateau with its average elevations of ∼1,000 m is often attributed to mantle processes, but there are conflicting theories for the timing and drivers of
Topographic constraints on magma accumulation below the actively uplifting Uturuncu and Lazufre volcanic centers in the Central Andes
Geodetic surveys of Volcan Uturuncu and the Lazufre volcanic complex in the Central Andes of South America reveal sustained surface uplift from magmatic intrusion at depth. However, the decadal
Cenozoic landscape evolution of the Kruger National Park as derived from cosmogenic nuclide analyses
In contrast to active tectonic settings, little is known about the potential feedback between surface processes and climate change in tectonically inactive cratonic regions. Here, we studied the
Investigating the sediment conveyor in arid Australia with cosmogenic nuclides
Assessing sediment production and transfer on a range of time and spatial scales is indispensable to understand Earth’s surface dynamics and landscape evolution processes. Linking and quantifying
A palaeoseismic trench investigation of early Holocene neotectonic faulting along the Kango Fault, southern Cape Fold Belt, South Africa– part II: earthquake parameters
The location and estimated magnitude of a recent surface rupturing earthquake along the eastern part of the Kango Fault traversing the southern Cape Fold Belt, South Africa, is reported here, as well


Slow Rates of Rock Surface Erosion and Sediment Production across the Namib Desert and Escarpment, Southern Africa
Slow erosion has characterized the Namib Desert, the Namibian escarpment, and the adjacent Namibian highlands over the Pleistocene. Paired analyses (n566) of in-situ-produced Be and Al in
Rock uplift rates in South Africa from isochron burial dating of fluvial and marine terraces
The high plateau of southern Africa is considered to be either uplifting due to mantle-driven dynamic topography, or to have been stable since Mesozoic rifting. To address this debate, we determined
Strong rocks sustain ancient postorogenic topography in southern Africa
The Cape Mountains of southern Africa exhibit an alpine-like topography in conjunction with some of the lowest denudation rates in the world. This presents an exception to the often-cited coupling of
Early Holocene Extensional Tectonics in the South-Eastern Cape Fold Belt, South Africa
The current seismo-tectonic model for South Africa depicts the south-eastern Cape Fold Belt as a tectonically stable intraplate-type environment, where earthquakes are relatively infrequent to rare,
Erosional equilibrium and disequilibrium in the Sierra Nevada, inferred from cosmogenic 26Al and 10Be in alluvial sediment
We used cosmogenic 26 Al and 10 Be in stream sediment to measure landscape-scale erosion rates for topographically diverse catchments at seven Sierra Nevada sites. At three sites, erosion rates and
