Argon data for Amazon Craton

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 09:05 PM | Dataset Last Updated: August 20, 2020 at 12:00 AM
This dataset accompanies planned publication 'Genesis of early Neoproterozoic gold deposits, southwestern Amazon Craton, western Brazil'. The Ar/Ar data is for samples that record the mineralization of the area. The geochronology provides time constraints for the mineralization studied in the manuscript. Samples were collected from the Amazon Craton region, and collection was done by Rodrigo Prudente de Melo of the Univ. Federal de Goias, who sent them to the USGS Denver Argon Geochronology Laboratory for Ar/Ar analysis.
