Short communication: A database of the global distribution of (U-Th) /He ages and U and Th contents of goethites

Abstract

Terrestrial supergene goethites of known ages record information on changes in weathering conditions through time. Here we present a database of (U-Th) / He ages and U and Th contents of goethites from different weathering environments around the globe. By consolidating published data collected at four different laboratories and unpublished data collected at the Noble Gas Laboratory at Caltech, we aim to give an overview of the work carried out by geochronologists and geochemists in the last 20 years. The database contains 2609 (U-Th) / He ages of goethites from 10 countries; most of the ages come from Brazil and Australia.
