  • Descrição: Lithic analysis, radiocarbon dating and luminescence dating are applied to a stratified open-air Paleoindian site in Central Brazil, lending some balance to a published record dominated by rock shelter sites. Most lithics are found in two discrete occupation layers. Lithics found outside these layers are attributed to post-depositional movement of small flakes mainly upwards. Single-grain luminescence dating on quartz grains also suggest post-depositional movement. Both wind and bioturbation are suspected mechanisms. The luminescence analysis does not provide precise depositional dates in this situation but does support such dates suggested by radiocarbon. ► Formation processes studied at a stratified open-air site in Central Brazil. ► Lithic analysis suggests two occupations with post-depositional disturbance. ► Single grain luminescence dating also shows post-depositional disturbance. ► Luminescence analysis lends reliability to dates provided by radiocarbon.
