Landscape responses to intraplate tectonism: Quantitative constraints from Be-10 nuclide abundances

Quigley, Mark; Sandiford, Michael. A; Fifield, L Keith; Alimanovic, Abaz

Description

Cosmogenic 10Be concentrations in bedrock and alluvium combined with structural studies provide a novel approach for identifying neotectonic forcing of landscape evolution in mildly deforming continental interiors. Measured 10Be concentrations in the Flinders Ranges indicate rapid and spatially variable rates of bedrock erosion in a catchment that has incurred at least three large, surface-rupturing earthquakes since ∼ 67 ka. 10Be-derived erosion rates are lower where late Quaternary...[Show more]
