About fires and paintings: Three stratigraphic insights on the history of a cave with prehispanic rock art by Gheco, Lucas Ignacio, Gastaldi, Marcos Roman, Marte, Fernando Daniel, Quesada, Marcos Nicolás, Tascon, Marcos, Mastrangelo, Noemi Elisa

“…Trying to answer this question, in this paper we propose a method to link three different approaches that share the same stratigraphic principle: the excavation of the cave's floor sediments, the confection of a Harris' matrix of the painting process of one of the panels with rock art; and the study and further chemical analysis (SEM-EDS and Raman) of micro samples taken from the figures painted and the rock underlying. …”

Archaeometrical characterization of pigments and paintings on Pre-Hispanic pottery from the regions of Fiambalá and Chaschuil (Catamarca, Argentina) by Ratto, Norma Rosa, Reinoso, Maria Elba, Basile, Mara Valeria, Freire Espeleta, Eleonora, Halac, Emilia Beatriz

“…Results indicate the continuity in use of certain pigments (mainly hematite for red hues and Mn oxides in combination with magnetite for black paints) within the different socio-political organizations that inhabited the region from the first to the 14th centuries ce, in spite of the diverse shades of colour, which suggests an intentional search linked with their cultural conventions. …”

The colors of San José pottery from Yocavil valley, Argentine Northwest. Strategy for the characterization of archaeological pigments using non-destructive techniques by Tomasini, Eugenia Paula, Palamarczuk, Valeria, Zalduendo, María Mercedes, Halac, Emilia Beatriz, Porto Lopez, Jose Manuel, Fuertes, María Cecilia

“…Using this strategy, we study the composition of paints and slips of different colors –cream, black and red– used by the old potters of the Yocavil valley (Catamarca Province, Argentine) to produce “San José” ceramics (ca. …”

Compositional data supports decentralized model of production and circulation of artifacts in the pre-Columbian south-central Andes by Lazzari, Marisa, Pereyra Domingorena, Lucas, Stoner, Wesley D., Scattolin, Maria Cristina, Korstanje, María Alejandra, Glascock, Michael

“…The results show: (i) intervalley heterogeneity of clays and fabrics for ordinary wares; (ii) intervalley homogeneity of clays and fabrics for a wide range of decorated wares (e.g., painted Ciénaga); (iii) selective circulation of two distinct polychrome wares (Vaquerías and Condorhuasi); (iv) generalized access to obsidian from one major source and various minor sources; and (v) selective circulation of volcanic rock tools from a single source. …”
