“…Like obsidian, rhyodacitic and dacitic glasses have a clear geochemical signature (Figures –11). Their absence in archeological records is not only due to the scarcity of these types of volcanic glasses but also because they can be easily confused with very fine‐grained basalts (Figure S2; Shackley, ).…”

In this study we used a multidisciplinary approach, coupling morphological, geological, geochemical, and statistical analyses to investigate the provenance of rhyodacitic and dacitic glass knapped at the Pilauco site (40°34′11” S, 73°06′17” W; 13,570 ± 70–12,540 ± 90 14C year BP) in northwestern Chilean Patagonia. A morphotechnological analysis was performed on the entire lithic assemblage, which is composed of cores, retouched and unretouched unifacial flakes, and small pieces of debitage, some of them closely associated with Notiomastodon aff. N. platensis gomphothere bones. Sixty‐two archeological and geological samples were analyzed by inductively coupled plasma mass spectrometry revealing a wide range of basaltic to rhyodacitic compositions. The archeological knappable dacitic and rhyodacitic glasses were recovered from pebbles deposited mainly on a beach away from the site, as deduced by the presence of minute and dense crescentic percussion marks on the cortexes. Geochemical trace element analysis suggests that the Puyehue–Cordón Caulle Volcanic Complex is the most likely source for the volcanic glass artifacts at Pilauco. The new morphotechnological and provenance record and improved stratigraphic sequences highlight the Pilauco site as an important contribution for the diversity of the South American geoarchaeological context.

Resumen En la cuenca lacustre de Zacapu a lo largo de su ocupación prehispánica (100 a.C. a 1450 d.C.), la dacita, una roca de origen volcánico, fue un recurso estratégico dentro de la economía regional, con el cual los antiguos habitantes de la zona elaboraron una serie de artefactos líticos ligados tanto a actividades de subsistencia y artesanales como rituales. Las investigaciones iniciadas en 2011 en dos minas-taller del yacimiento de dacita del Cerro Vicente expusieron una explotación extensa y organizada en torno a este recurso. En 2015, a partir de la cobertura LiDAR, se identificó un tercer complejo minero con evidencias de una explotación a cielo abierto y subterránea, esta vez en el yacimiento de Las Minas. Con el fin de comprender los mecanismos de explotación de la dacita, se ha llevado a cabo un análisis espacial de este sitio con distintas escalas de aproximación, para caracterizar las evidencias materiales vinculadas con la actividad extractiva. La combinación en nuestra investigación de la información que aporta el LiDAR y la proveniente de la prospección en el campo, nos ofrece un panorama completo del yacimiento, su organización espacial y funcional en un contexto más amplio como un paisaje prehispánico de extracción.

“…The detailed on-site visual sedimentary facies and sequence analysis have clearly outlined a restricted distribution of anthropogenic and cultural deposits confined mainly to small archeological features (pits, graves, wells, postholes) (Barham, 1995;Barham and Macphail, 2016). Consequently, the settlement strategy and patterns of former cultures as well as the remaining attesting cultural deposits were controlled by the geological, geomorphological endowments of the site and its vicinity from the Late Glacial to the modern times (Bates and Bates, 2000;Shackley, 1975;Rapp, 1975;Rapp et al, 1974;Rapp and Gifford, 1982;Starkel, 1991;Starkel et al, 2009). Thus, following the identification, delineation and visual description of the individual geomorphological units uniform chronological, sedimentological, geoarchaeological, envi-ronmental historical investigations have been implemented following the mentioned workflow.…”

This study presents the results of a comprehensive geoarchaeological study implemented at an archeological site covering ca. 5 ha near the city of Csorna on the NW part of the Danube Plain, NW Hungary. The site itself exposed a complex fluvial system of an ice age creek with near bank and overbank areas (levee, point bar, back swamp). Spatial distribution of archeological features allowed for the interpretation of differential use of the fluvial landscape by different cultures. According to our data, the referred fluvial system must have emerged during the Late Glacial. At this time, creeks originating from hills to the SE followed a uniform NW trajectory. From the Holocene, small creeks were beheaded turning into inactive flood channels. It was the time when the gradual infilling of the floodplain started. Alternating layers of floodwater coarses and floodplain fines mark recurring floods at our site. These could have been correlated with cooler, wetter climatic phases of the North Atlantic, Western Europe and high stands in Central European lakes. Highest floods are recorded during the Late Bronze and Iron Ages besides the Neolithic. Pollen data enabled us to make inferences on the vegetation as well.
