Associated scholarship(s):20/04283-0 - Anthropogenic and non-anthropogenic sediments in rock shelter settings: using micromorphology and mineralogical analysis to tackle formation processes in Abrigo do Alvo, Abrigo Roncador and Abrigo Maximiano archaeological sites, São Paulo state, Brazil, BE.EP.DR


Humans contribute both intentionally and incidentally to the formation and transformation of the environment in which they live. Such contributions include manufacturing objects and constructions that are usually the major focus of archaeologists, as well as sediments and soils. The present PhD project aims to understand the interaction between people and sediments and soils by means of a geoarchaeological approach to archaeological site formation processes in three rockshelters located in São Paulo state. This proposal is articulated in two case studies: 1) comparison of depositional and post-depositional processes in the Abrigo do Alvo and Abrigo Roncador rockshelters, located within the Analândia municipality; 2) the study of anthropogenic contributions to the sediments of the Abrigo Maximiano rockshelter, located in the Iporanga municipality. Methods proposed are based on Geochemistry, by means of a multi-technique comparative analysis of sediment samples from inside and outside the rockshelters. The use of Instrumental Neutron Activation Analysis (INAA) and X-Ray Fluorescence (XRF) for elemental determination, and of X-Ray Diffraction (XRD) for mineral composition, is proposed. Other methods may also be integrated according to each case study. The increasing need to use Geochemical techniques in archaeology, as well as the scarcity of geoarchaeologists trained in these techniques in Brazil, justify this project. (AU)
