The many surface expressions of mantle dynamics
J Braun - Nature Geoscience, 2010 - nature.com
Plate tectonic theory suggests that present-day topography can be explained by the
repeated interactions between the tectonic plates moving along Earth's surface. However …

Provenance of Kalahari Sand: Paleoweathering and recycling in a linked fluvial-aeolian system
We here review what is known about the dunefields and fluvial systems of the Kalahari
Basin in terms of geological setting and Quaternary dynamics and set out what has been …

Estimating uplift rate histories from river profiles using African examples
GG Roberts, N White - Journal of Geophysical Research: Solid …, 2010 - Wiley Online Library
We describe and apply a method for estimating uplift rate histories from longitudinal river
profiles. Our strategy is divided into three parts. First, we develop a forward model, which …

Earthquake distribution patterns in Africa: Their relationship to variations in lithospheric and geological structure, and their rheological implications
We use teleseismic waveform inversion, along with depth phase analysis, to constrain the
centroid depths and source parameters of large African earthquakes. The majority of seismic …

Oceanic residual depth measurements, the plate cooling model, and global dynamic topography
MJ Hoggard, J Winterbourne… - … Research: Solid Earth, 2017 - Wiley Online Library
Convective circulation of the mantle causes deflections of the Earth's surface that vary as a
function of space and time. Accurate measurements of this dynamic topography are …

Surface wave tomography: imaging of the lithosphere–asthenosphere boundary beneath central and southern Africa?
S Fishwick - Lithos, 2010 - Elsevier
The lithosphere–asthenosphere boundary (LAB) remains a controversial subject in Earth
sciences, and beneath cratonic regions appears to be a particularly difficult boundary to …

Elevated, passive continental margins: Not rift shoulders, but expressions of episodic, post-rift burial and exhumation
P Japsen, JA Chalmers, PF Green… - Global and Planetary …, 2012 - Elsevier
Many studies of elevated, passive continental margins (EPCMs) assume that their
characteristic, large-scale morphology with high-level plateaux and deeply incised valleys …

Uplift histories from river profiles
Longitudinal river profiles, where elevation of a river bed is plotted as a function of distance
along the river bed, contain information about uplift rate. When a region adjacent to a …

Planation surfaces as a record of mantle dynamics: the case example of Africa
There are two types of emerged relief on the Earth: high elevation areas (mountain belts and
rift shoulders) in active tectonic settings and low elevation domains (anorogenic plateaus …
