Figure 5 Depth profile of cosmogenic nuclides (circles) with model-best-fit (curve) concentrations based on steady denudation (Equation 2).
This was based on the recall since birth.
Here, we evaluate spatial variations in denudation of the Spanish Betic Cordillera based on cosmogenic 10Be-derived denudation rates.
Finally, denudation based on currently observed erosion rates would have lead to the destruction of most badlands a long time ago.
We present new studies that define the rates of landscape denudation during the major part of the Holocene (the last 10,200 years): one based on the Iceland shelf sediment record, the other from the sediment record in the glacier-fed lake, Hvítárvatn.
Based on terrain analysis for the denudation sites, the debris volumes at the collapsed and deposited areas are 31,896,667 m3 and 39,537,067 m3, respectively.
The plots show close agreement between denudation rates based on 10Be and 26Al, within error limits, inside the 'erosion-island' area, supporting that these samples do not record complex exposure histories.
Using a mass balance approach, we estimate the volume/unit length of continental material eroded seaward of the escarpment to be between 41 and 68 km2, approximately an order of magnitude less than the 339 km2 of terrigenous sediments calculated to have been deposited offshore, but consistent with earlier denudation estimates based on apatite fission track data.
We used three steps to develop the lateral tibiofemoral CDI based on areas commonly affected by denudation.
A simple empirical relationship based on temperature, precipitation and long-term denudation rates explains 89 95% of the variation in long-term weathering rates across our network of sites.
