Two MATLAB programs for computing paleo-elevations and burial ages from paired-cosmogenic nuclides

Methods based on cosmic-ray produced nuclides are key to improve our understanding of the Earth surface dynamic. Measuring multiple cosmogenic nuclides in the same rock sample has a great potential, but data interpretation requires rigorous and often complex mathematical treatments. In order to make progress on this topic, this paper presents two easy-to-use MATLAB© programs permitting to derive information from pairs of cosmogenic nuclides ( 26 Al- 10 Be or 10 Be- 21 Ne) measured in rock samples that have been exposed to cosmic rays in the past: "Paleoaltitude.m" and "Burial.m" Codes available here as supplementary material. •"Paleoaltitude.m" computes paleoelevations from a sample whose burial age is known. This new paleoaltimetry method is presented in detail in Blard et al. [1]. The present article also develops the mathematical approach. •Since the elevation of exposure may affect the accuracy of a burial age [1], the second MATLAB© script "Burial.m" is designed to compute burial ages from 26 Al- 10 Be or 10 Be- 21 Ne pairs, taking into account the position of a sample (elevation and latitude) during its preburial exposure history.
