King 1839, Fitz-Roy 1839, Hyades y Denniker 1891), pasando por las monografías etnográficas de principios del siglo XX (por ej. Gusinde 1982 [1931), así como algunos datos arqueológicos del período post-contacto con los europeos (Legoupil 1989, Mansur y Pique 2012; Parmigiani et al. 2013), dan cuenta del uso de materiales provenientes de occidente, como el metal o el vidrio, obtenidos directa o indirectamente por las poblaciones originarias de Patagonia austral para la confección de una variedad de herramientas.
En este contexto, el objetivo principal de este trabajo es presentar los resultados preliminares de un programa experimental que se está desarrollando para estudiar las huellas tecnológicas producidas por el uso de compresores de metal en el trabajo de formatización de diversos artefactos por presión. Nuestro objetivo es identificar los criterios diagnósticos macroscópicos y microscópicos de la utilización de estas herramientas de talla, y poder diferenciarlos de los producidos por los compresores de hueso o asta y madera. Hemos utilizado dos materias primas presentes en contextos arqueológicos diferentes de momento post contacto en Patagonia Austral Batchelor 1, Punta Baja 1 y Ewan: obsidiana y vidrio respectivamente, que tienen propiedades muy similares para la talla. Analizamos macro y microscópicamente los rastros producidos en los artefactos retocados y restos de talla, así como algunos de sus atributos técnicos.
En términos generales hemos podido observar una mayor cantidad de daño (abrasión, estrías, resquebrajaduras y trituramiento) tanto en los instrumentos fabricados como en los talones de las microlascas obtenidas en la talla al utilizar el compresor metálico. De igual modo, se identificaron residuos de metal observables tanto a bajos aumentos (lupa) como a altos aumentos (microscopio) en un porcentaje importante de los artefactos.
Los resultados obtenidos servirán para la interpretación de los conjuntos líticos de los sitios mencionados. En ellos está representada la técnica de la presión para la fabricación de instrumentos.
Ethnographic and ethnohistorical information, at least from the stories of navigators and scientific expeditions from the late eighteenth century and throughout the nineteenth century (por ej. King 1839, Fitz-Roy 1839, Hyades and Denniker 1891), through the ethnographic monographs of Early twentieth century (por ej. Gusinde 1982 [1931]), as well as some archaeological data from the post-contact period with Europeans (Legoupil 1989, Mansur and Pique 2012, Parmigiani et al., 2013), account for the use of materials from the West, such as metal or glass, obtained directly or indirectly by the native populations of southern Patagonia for the preparation of a variety of tools.
In this context, the main objective of this work is to present the preliminary results of an experimental program that is being developed to study the technological footprints produced by the use of metal compressor in the work of formatting various pressure artifacts. Our objective is to identify the macroscopic and microscopic diagnostic criteria of the use of these size tools, and be able to differentiate them from those produced by compressors of bone or antler and wood. We have used two raw materials present in different archaeological contexts of post-contact moment in Southern Patagonia Batchelor 1, Punta Baja 1 and Ewan: obsidian and glass respectively, which have very similar properties for the size. We analyze macro and microscopically the traces produced in the retouched artifacts and carvings, as well as some of their technical attributes.
In general terms we have been able to observe a greater amount of damage (abrasion, grooves, cracks and crushing) both in the manufactured instruments and in the heels of the micro-flakes obtained in the size when using the metallic compressors. Likewise, observable metal residues were identified both at low magnifications (magnifying glass) and at high magnifications (microscope) in a significant percentage of the artifacts.
The results obtained will serve for the interpretation of the lithic assemblies of the aforementioned sites. In them the technique of pressure for the manufacture of instruments is represented.

The goal of this analysis is to establish bases from which to interpret regional trends in the distribution of the archaeological record that connect these areas, which have been traditionally considered to be geographically decoupled. We propose a standardized methodology for selecting ages that provide a reliable human signature. Variations in date frequencies in a regional scale are discussed with the use of summed probability distributions. Radiocarbon voids at the regional level previously identified in Midwest Argentina are explored. Regional chronological information is compared to the available paleoenvironmental records, thereby emphasizing the possible role of climate pulses in the spatial organization of human populations. Significant arid conditions between 7800 and 5700 cal BP are coincidental with a focused occupation of the Andes Mountains, area which may have offered stable resources; thus more effectively occupied when compared to other environmental bands.
Keywords: radiocarbon dates; climate change; human paleoecology; hunter-gatherers; mid-Holocene; Subtropical Andes.
