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

Description

Cosmogenic 10Be concentrations in exposed bedrock surfaces and alluvial sediment in the northern Flinders Ranges reveal surprisingly high erosion rates for a supposedly ancient and stable landscape. Bedrock erosion rates increase with decreasing elevation in the Yudnamutana Catchment, from summit surfaces (13.96 ± 1.29 and 14.38 ± 1.40 m Myr-1), to hillslopes (17.61 ± 2.21 to 29.24 ± 4.38 m Myr-1), to valley bottoms (53.19 ± 7.26 to 227.95 ± 21.39 m Myr-1), indicating late Quaternary increases...[Show more]
