Une lecture pluridisciplinaire des analyses chimiques et minéralogiques de peintures rupestres de la Patagonie argentine

This paper gathers the conclusions of a research whose principal aim was to inquire about the knowledge and technological skills possessed by the artisans painters of northern argentinian Patagonia during pre- and postcolumbian times. The study focused on the material properties of the paints that aborigine societies were executing to display their graphic language. The organic and inorganic components were analyzed: pastes, patinas and coloring raw material. It was tried to determine what pigments, binders, additives and fasteners were used and what recipes were applied. During the development of the project, historical and ethnography information were analyzed, which allowed us to design actualistic studies. A multidisciplinary reading from the archaeology, the geology and the chemistry was needed to interpret the corpus of information.
