Abstract
Land surface ages are often estimated using the concentration of in situ cosmogenic nuclides. These nuclides are produced by the reaction between cosmic rays and surface materials. The amount of these nuclides increases as cosmic rays reach the Earth’s surface, while radioactive nuclides decrease over time due to their half-lives. Various scaling methods and studies have been conducted worldwide to model the production rate of these nuclides. By applying these production processes and rates, land surface ages can be estimated, such as the exposure age of the surface, erosion rates, or burial rates. This study introduces an example of determining surface exposure ages using 10Be, one of the in situ cosmogenic nuclides.
