Erosion is an exogenic agent of landscape evolution.Quantitatively calculation of erosion rates and the reveal of the climate-erosion-tectonics feedback system are important research subjects in Geosciences.The average rates of exhumation can be obtained from thermochronology on time scale of millions of years,and erosion rates from hydrological measurement on time scale of tens of years.As a supplement,erosion rates on time scale of ten thousands of years can be calculated by measuring cosmogenic nuclide(¹⁰Be and ²⁶Al)from river terrace deposits or basin sediments.Cosmogenic nuclides were primarily generated by reaction of quartz grains exposed near earth surface by galactic cosmic radiation,which were then suddenly and deeply buried to shield off cosmicrays after exposure of short time on the ground surface.Generally,the quartz grains have a short time exposure and low cosmogenic nuclide concentration.In addition,the cosmogenic nuclide decreases over time after burial.Quantitatively calculation of erosion rates from ¹⁰Be and ²⁶Al is a concept based on dating river terrace deposits or basin sediments by determination of ¹⁰ Be concentration.Combining ¹⁰Be and ²⁶Al measurements,surface exposure ages or erosion rates can then be calculated.The method is precise,easily accessible and widely applicable.It can be used for longer time scales and broader spatial scales,and it is a new method important to landscape evolution research from Quaternary to Holocene.
