Geomorphic Controls on Andean Denudation Rates
To predict erosion rates throughout the Andes, we conducted a multiple regression analysis of the sediment discharge from 47 drainage basins in the Bolivian Andes and various topographic, climatologic, and geologic parameters. These mountainous basins are typically large (17–81,000 km; km), often have decades of measurement mean p 11,000 data on daily water and sediment discharge, and display a...
متن کاملRapid, long-term rates of denudation
High rates of erosion (1-15 mm/yr) of fluvial strata have persisted over intervals of 0.2-1.5 m.y. and across areas of 60-2000 km 2 in the Cenozoic foreland basin of northern Pakistan. These rates occur in areas associated with thrust shortening, and they indicate that erosion nearly kept pace with the rates of latest Miocene to Pleistocene uplift. Such high rates of erosion are predicted to pr...
متن کاملMeasurement of long-term denudation rates in carbonate landscapes using in situ-produced 36Cl cosmogenic nuclide
ecent progresses have been made in the quantification of denudation of eroding landscapes and its links with topography. Despite these advances, data is still sparse in carbonate terrain, which covers a significant part of the Earth’s surface. We can now measure in situ-produced cosmogenic nuclides concentrations in various near-surface materials, allowing accurate quantification of the rates o...
متن کاملEstimating Rates of Denudation Using Cosmogenic Isotope Abundances in Sediment
We propose, as a testable hypothesis, a basin-scale approach for interpreting the abundance of in situ produced cosmogenic isotopes, an approach which considers explicitly both the isotope and sediment flux through a drainage basin. Unlike most existing models, which are appropriate for evaluating in situ produced cosmogenic isotope abundance at discrete points on Earth’s surface, our model is ...
