Hunter-gatherer manufacture, use, and discard of blades at the northern margin of Viedma Lake (southwest of Santa Cruz, Argentina): Late Holocene differences in landscape use

Mostrar todas las versiones(2)

Using a morphological, technological, and use-wear analysis approach, we study assemblages of blades and by-products of their manufacture (laminar flakes, chunks, cores, and tools) recovered on Viedma lake northern shore. The artifactual samples come from different archaeological contexts of altitud...

description Using a morphological, technological, and use-wear analysis approach, we study assemblages of blades and by-products of their manufacture (laminar flakes, chunks, cores, and tools) recovered on Viedma lake northern shore. The artifactual samples come from different archaeological contexts of altitudinal sectors of the steppe (Coast —wintering fields, ≤ 400 m asl—, Intermediate Pampas and Tobiano Plateau ≥ 900 m asl) related to Late Holocene chronologies. The higher frequencies of flintknapping and discard evidences, in addition to the integrity of the samples, the artifactual composition, and the high availability of basalt nodules of dimensions and qualities suitable for flintknapping, show the manufacture and immediate use of blades within the framework of expedient strategies in residential spaces of the coast. The efficiency of blades to perform cutting tasks could be linked to the processing of guanaco. Thus, the blade assemblages recovered at the coast support a substantial difference in the hunter-gatherer use of the northern shore of Viedma lake. It is proposed that the production of blades has a supraregional manifestation shared by areas of the Tar and Argentino lake coasts, located to the North and South of Viedma lake, respectively. The characteristics of the archaeological contexts with higher blade frequency would explain their use within a background provided by flake technology.

Desde un acercamiento morfológico, tecnológico y de análisis funcional se analizan conjuntos de hojas y subproductos de su manufactura (lascas de módulo laminar, chunks, núcleos y artefactos formatizados) recuperados en la margen norte del lago Viedma. Las muestras artefactuales provienen de distintos contextos arqueológicos de sectores altitudinales de la estepa (Costa-campos de invernada, ≤ 400 m s.n.m., Pampas Intermedias y Meseta del Tobiano ≥ 900 m s.n.m.) asociados con cronologías del Holoceno tardío. Las mayores frecuencias de evidencias de la talla y descarte, además de la integridad, la composición artefactual de las muestras y la alta disponibilidad de nódulos de basalto de dimensiones y calidades aptas para la talla, muestran la manufactura y el uso inmediato de hojas en el marco de estrategias expeditivas en espacios residenciales en la Costa. El uso de las hojas, eficaces para realizar tareas de corte, se vincularía con el procesamiento integral del guanaco. Así, los conjuntos de hojas de la Costa sustentan una marcada diferencia en el uso cazador-recolector de la margen norte del lago Viedma. Se propone que la producción de hojas tiene una manifestación suprarregional compartida por espacios de las costas de los lagos Tar y Argentino, ubicados al norte y al sur del lago Viedma, respectivamente. Las características de los contextos arqueológicos donde aparecen las mayores frecuencias de hojas explicarían la utilización de esta tecnología contra un telón de fondo provisto por la tecnología de lascas.
