Abstract

Modal sand compositions in nine rivers draining the proximal part of the Amazonian retroarc foreland basin in Peru and Bolivia provide support for the Recycled Orogen provenance model of Dickinson and Suczek. The overriding control on sand composition is the relative area of bedrock type exposed in the fold-thrust belt. Sands reworked from Tertiary and Quaternary foreland-basin fill are relatively enriched in quartz, possibly owing to intense weathering of sediments in the soil profile. -from Authors
