The Radiogenic Isotope Laboratory is a multi-user, multi-funded research laboratory that utilizes state-of-the-art isotopic techniques to solve geologic problems. Isotope research techniques are exceptionally powerful tools to essential baseline regional and local mapping studies as well as resource, hazard, environmental, surficial processes, and global change studies. Isotopic data may also be used to help understand biological, ecological and hydrological processes. The Radiogenic Isotope Laboratory located in Denver, Colorado, provides both geochronological and isotopic tracer studies applied to both natural and artificial systems.
