Long-term dependence in exchange rates

Measurement 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...
