Investigating a Rock Art Site in Paraná State, South of Brazil
Jaguariaíva 1 is a sandstone rockshelter located in Jaguariaíva, Paraná State, Brazil, with rock art on the surface of the walls and ceiling. A stratigraphic analysis of the soil within the shelter showed six occupational layers and a superficial disturbed layer with evidence from the end of the 19th century. The establishment of a rock-art chronology became possible using fallen painted rock sections incorporated into three sedimentary levels un…
Optimization of the Amount of Zinc in the Graphitization Reaction for Radiocarbon AMS Measurements at LAC-UFF
The Radiocarbon Laboratory of the Universidade Federal Fluminense, in Brazil, has been successfully applying the zinc reduction method for graphitization of carbon samples since the development of its early protocols in 2009. Successive methodological research aiming to improve and, ultimately, optimize the precision and accuracy of our results indicates that graphitization temperatures as low as 460°C promote erratic 13 C isotopic fractionation,…

Métodos e técnicas de caracterização aplicadas ao estudo do patrimônio cultural
O Laboratório de Física Nuclear Aplicada da Universidade Estadual de Londrina (LFNA/UEL) introduziu, em 1994, a arqueometria entre as suas principais linhas de pesquisas. Este trabalho é uma avaliação dessas atividades bem como da formação de recursos humanos até a presente data. Estas atividades podem ser divididas em quatro níveis: 1. Implementação de metodologias experimentais. Para cada método experimental utilizado, é necessário uma pesquisa…
