Taphonomic analysis of surface lithic assemblages in aeolian contexts of the north coast of San Matías gulf, Río Negro (Argentina)

Mostrar todas las versiones(2)

The northern sector of the San Matias Gulf has archaeological loci and radiocarbon dates of human occupations corresponding to the Middle and Late Holocene. Previous results suggest that the interaction between aeolian processes (corrosion, transport, and deposition) and the characteristics of the a...

description The northern sector of the San Matias Gulf has archaeological loci and radiocarbon dates of human occupations corresponding to the Middle and Late Holocene. Previous results suggest that the interaction between aeolian processes (corrosion, transport, and deposition) and the characteristics of the assemblage (artifact granulometric composition) influence the archaeological record configurations. In this paper, the results from the taphonomic analyses of surface lithic assemblages recovered from four archaeological sites are presented and compared. The localities are located mainly on two types of geoforms (dunes and old marine terraces) with differential preservation. Besides, the results of the technomorphological analyses that are relevant for assessing the postdepositional history of the artifacts and the potential taphonomic biases are presented and integrated. The results obtained allowed us to identify general trends. The taphonomic evidence suggests conditions of greater relative stability in the assemblages recovered in dunes and less stability for assemblages from terraces. For the technological aspect, previous studies are resumed, emphasizing specific attributes and their frequency in the different samples. An integrative analysis of these two analytical dimensions allowed us to reconstruct the various postdepositional trajectories of the assemblages linked to the different locations, estimate their differential representation, and contextualize the human occupations in the different coastal spaces over time.

El sector norte del golfo San Matías posee loci arqueológicos y fechados radiocarbónicos con ocupaciones humanas correspondientes al Holoceno medio y tardío. Los resultados obtenidos previamente sugieren que la interacción entre procesos eólicos (corrasión, transporte y depositación) y las características del conjunto (composición granulométrica artefactual) influyen sobre las configuraciones del registro arqueológico que hallamos actualmente. En este trabajo se presentan y comparan los resultados obtenidos del análisis tafonómico de los conjuntos líticos de superficie recuperados en cuatro localidades arqueológicas. Estas se emplazan principalmente en dos tipos de geoformas (dunas y antiguas terrazas marinas), con características de preservación diferencial. Asimismo, se presentan e integran los resultados del análisis tecno-morfológico que son relevantes para la evaluación de la historia postdepositacional de los artefactos y los potenciales sesgos tafonómicos existentes. Los resultados obtenidos permiten identificar tendencias generales. A partir del análisis tafonómico se evidencian condiciones de mayor estabilidad relativa para aquellos conjuntos recuperados en dunas, y una menor estabilidad para los conjuntos sobre terrazas. En relación con el aspecto tecnológico, se retoman estudios previos y se pone énfasis en determinados atributos y su frecuencia en los distintos muestreos. Un análisis integrador de estas dos dimensiones analíticas permitió reconstruir las diversas trayectorias postdepositacionales de estos conjuntos vinculadas a las distintas localizaciones, estimar su representación diferencial y contextualizar las ocupaciones humanas en los distintos espacios costeros en el tiempo.
