Argon data for Amazon Craton
type: Dataset
description: 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.
