Ceramic pastes and sand samples: Petrographic comparison and approach to raw materials procurement in the southern Pozuelos basin (Jujuy, Argentina)

Abstract

With the aim of undertaking a rst assessment of ceramic raw material procurement in the southern Pozuelos Basin, we present petrographic comparisons between ceramic pastes, analyzed in previous contributions, and sand samples from the study area. e samples were prepared and studied using a binocular magnifying glass, as well as under a petrographic microscope, taking into consideration similar elements to those observed on the ceramic pastes. e geological literature for the study area was also reviewed. Results allow us to suggest that a set of ceramic paste groups with related compositions, were manufactured using local raw materials. is was done on the similarities observed in the petrographic characteristics of their inclusions, and those of the sand particles. Another set, related to the Yavi style, was probably non-local to the southern Pozuelos Basin. Finally, a small set of paste groups belonged to the post- Hispanic period, and were probably non-local too.
