Luminescence dates for the Paleoindian site of Pedra Pintada, Brazil
International audienceDates are presented for the Paleoindian levels of Pedra Pintada cave in Brazil, based on the thermoluminescence (TL) and optically stimulated luminescence (OSL) study of ten specimens of heated siliceous stones and three of sand, respectively. Also discussed are the details of preliminary mineralogical, radiographic, and analytical work done on the lithic specimens in France and the OSL work done on the sediments in the US. The luminescence dates are in agreement with radiocarbon dates for the same strata
