Spatial and temporal variability in the use of lithic raw materials for flaked stone technology in northeast Chubut Province (North Patagonia) during the Late Holocene

Archaeology of coastal hunter-gatherer occupations in the Southern Cone

“…In this volume, some papers presents and discuss the archaeological record of various sites and areas in several regions of the Southern Cone such as the Atacama desert (Olguin et al, 2015), central Chile (Campbell, 2015), Tierra del Fuego (Borazzo and Borrero, 2015), Patagonia (eg., Hammond et al 2015;Banegas and Goye, 2015; among others), Southern South America (Zangrando and Tivoli, 2015), Buenos Aires province (Aldazabal and Eugenio, 2015) and La Plata river (Erchini et al 2015). These publications cover the three countries of the Southern Cone (Argentina, Chile and Uruguay) (Fig.…”

“…Hammond et al (2015) make a comparative study of lithic artifactual assemblages recovered from systematic excavations of shell middens on the northern coast of Santa Cruz (Patagonia Argentina) in order to discuss functionality and integrity of the archaeological sites, and also to evaluate general trends of the technological organization, and specially the activities that hunter gatherers carried out on shell middens and the exploitation of lithic raw materials on this part of Patagonia. Banegas and Goye (2015) discuss the existence of changes in the selection and use of raw materials for flaked stone tools during the Late Holocene in the north of Chubut Province (Argentina), considering two temporal blocks; meanwhile Alberti and Cardillo present a first description of lithic raw material sources (primary and secondary), and the particular geological and geomorphological characteristics of the southern coast of Río Negro province, discussing the procurement and exploitation strategies for these raw materials and the existence of temporal and spatial variations in raw material availability across different sectors of space. G omez Otero et al (2015) analyze certain discrepancies between the archaeofaunal remains recovered in the northern coast of Chubut province (Argentina) and the human stable isotopic record, specially the high value of sea resources of high trophic level and terrestrial plants.…”

The Forerunners on Heritage Stones Investigation: Historical Synthesis and Evolution

“…The first stones used as construction material came from the vicinity of the place where they would be used. They were used as prehistoric tools [5,6], amulets [7], support for petroglyphs [8,9], projectiles [10], support for inscriptions of important events or laws [11], walls [12], monuments, dikes, warehouses, paving [13] and all kinds of constructions [14]. Stones have also been used to manufacture mortars [15][16][17], ceramics [18,19], bricks [20,21] and mosaics [22].…”

Disponibilidad y selección de xilópalos en la costa norte y sur de la Provincia de Chubut, Patagonia Argentina

“…Estudios previos de caracterización de la base regional de recursos líticos en la costa norte y valle inferior del río Chubut, determinaron una muy escasa representación de los xilópalos en los muestreos (<1,5%); la mayoría de los cuales proviene de fuentes secundarias, en especial con morfología de rodado (Gómez Otero et al 1999;Banegas y Goye 2014;Banegas et al 2016). Sin embargo, es relativamente superior la presencia 26 DOI: http://doi.org/10.31048/1852.4826.v13.n1.23544 ISSN 1852-060X (impreso) / ISSN 1852-4826 (electrónico) de los xilópalos en los conjuntos arqueológicos (entre 5% y 6%), destacándose variabilidad en cuanto a la procedencia de las piezas -fuentes primarias y secundarias (guijas, guijarros, tabletas)-y los tamaños, colores y calidad para la talla (Banegas et al 2016).…”
