Paper No. 13
Presentation Time: 11:15 AM

A CONSTRAINED MONTE CARLO APPROACH TO MODELING PROFILES OF COSMOGENIC NUCLIDES


HIDY, Alan J., Department of Earth Sciences, Dalhousie University, Halifax, NS B3H 3J5, Canada and GOSSE, John C., Earth Sciences, Dalhousie University, 3006 LSC Edzell Castle Circle, Halifax, NS B3H3J5, Canada, alanhidy@dal.ca

We present and demonstrate a user-friendly and versatile Monte Carlo simulator for modeling profiles of terrestrial cosmogenic nuclides. Our program permits the incorporation of site-specific geologic knowledge to calculate most probable values for exposure age, erosion or denudation rate, and inherited nuclide concentration and provides a rigorous treatment of uncertainties for these parameters. The simulator will soon be available for download and a web interface is currently being written for full functionality over the internet.
