Description

This study aimed to determine the age of a prehistoric campfire from Serido region in northeastern Brazil. The dating was performed by Infrared Stimulated Luminescence (IRSL) by the method of multiple aliquot regenerative doses. Samples were collected from five different parts of the campfire in order to determine the accumulated dose, and samples of two parts of the campfire for determine the annual dose rate. After a statistical analysis of these values, we calculated an average age of 3640 +- 710 years. This age allowed to define a time frame for archaeological studies in this region. (author)
