dc.description.abstract | The origin of relatively high topography in intraplate settings is elusive. The St. Fran-cois Mountains, a tectonically inactive region with high relief, a Mesoproterozoic granite and rhyolite core, and Paleozoic sedimentary flanks, provide insights into the evolution of intraplate landscapes. We determined 14 in situ 10Be exposure ages, 23 10Be catchment-wide denudation rates (CWDRs), and geomorphic indices using a geographic information system, and we modeled surface uplift using an isostatic-flexure model. CWDRs varied from similar to 5 to 10 +/- 1.7 mm/k.y. and averaged 1.5 times greater in streams draining granite and rhyolite than in those draining flanking sedimentary rocks. In situ results from bedrock strath ter-races gave Quaternary incision ages and incision rates that were tenfold higher than CW-DRs. Major knickpoints (locally called shut-ins), all at 200 +/- 70 m elevation, are located at contacts between the igneous and sedimentary rocks. Our exposure and denudation results inform isostatic-flexural modeling, which together support the conclusion that late Quater-nary-Recent surface uplift driven by differential density and erosion focused in the igneous core is creating significant topography and relief in this intraplate setting. | - |
