Abstract

The study of microscopic materials is increasingly being incorporated by geoarchaeologists to tackle human-environment interactions at the soil/sedimentary matrix of landscapes and sites. This BEPE project aims at studying depositional and post-depositional human- and non-human-induced processes in three sheltered archaeological sites from south-eastern Brazil, by analysing microscopic components with micromorphology and Fourier transform infrared (FTIR) spectroscopy. Using both intact and bulk sediment samples from Abrigo do Alvo, Abrigo Roncador and Abrigo Maximiano rock shelter sites as well as from off-site contexts, I look forward to studying fabric and components which are not detectable by other techniques. Analyses will be carried out during a five-month internship (from January to June 2021) at the Charles McBurney Laboratory for Geoarchaeology, University of Cambridge, United Kingdom. This will substantially contribute to the understanding of the mineral and non-mineral components that make up the depositional history of the three sites. And it will bring fundamental clues to the possible effect of authigenic minerals (e.g. phosphates) to the preservation of archaeological materials, such as bones in the Abrigo Roncador site. The internship is also intended to get in touch with scholars and the newest perspectives and current debates about geoarchaeology in a leading international environment.
