Cosmogenic dating of fluvial terraces in the Sorbas Basin, SE Spain
… is poorly constrained due to the difficulties in dating river terraces. This study applies the technique of cosmogenic exposure dating to a fluvial staircase, for the first time, in the Sorbas Basin, SE Spain. Cosmogenic exposure dating allows the timing of abandonment of the fluvial terraces to …

Tectonic-Climate Interactions And Glacial History Within The Chugach And Kenai Mountains, Alaska
… utilized low temperature thermochronometry and cosmogenic dating to constrain the spatial and temporal distribution of exhumation and glacial history in order to characterize the net effect of glaciers on an orogen that experiences slow rock uplift. We constrain the spatial distribution of …

Fluvial Response to Intra-Canyon Lava Flows, Owyhee River, Southeastern Oregon
… mostly obscured by younger geologic units. From cosmogenic dating of fluvial features and 40Ar/39Ar dating of lava flows, estimates of mean incision rates through and the around the West Crater flow range from 0.27 mm/yr at Airplane Point to 3.3 mm/yr at Dog Leg Bar. No deposits from catastrophic …

New constraints on the late Cenozoic incision history of the New River, Virginia
… periods of stalled downcutting and aggradation. Cosmogenic 10-Be exposure dating, aided by mapping and sedimentological examination of terrace deposits, is used to constrain the timing of events in this history. Fill-cut and strath terraces at elevations 10, 20, and 50 m above the modern river …
