Buscamos avanzar en una agenda de investigación que promueve la desnaturalización de los bofedales, destacando el valor de la arqueología en diálogo con las comunidades y otras disciplinas para la comprensión de estos espacios. Presentamos resultados preliminares obtenidos en Mulluri, Parcohaylla y Surire (Puna Seca, Chile), donde analizamos la org...
This project employs a geoarchaeological approach to explore human occupation of the highland wetlands (bofedales) and salt flats of the Dry Puna of northern Chile (>2500m above sea level) during the Holocene. Differences in the archaeological record of each ecosystem are tentatively suggested to relate to settlement patterns and the history of the...
We present a detailed geomorphological characterisation of the Caracota Valley (18°49 ′ S 69° 11 ′ W, 4200-4600 m) in the western Altiplano of Northern Chile. A complex pattern of Pleistocene and Early Holocene glacier activity is responsible for the today's landscape configuration. Wetlands and temporary lakes significantly characterise the Caraco...
Bone caves such as sinkholes constitute remarkable sources of information for researchers interested in the paleoecology of fossil faunas. Moreover, these accumulations contain assemblages not or little affected by human intervention and can, therefore, serve as a source of comparison and contrast with contemporaneous assemblages from archaeologica...
Architectural features and shell-matrix sites are one of the most challenging records for archaeological inter- pretation, due to their intricate stratification and complex depositional paths. In the hyperarid coast of the Atacama Desert, hunter-gatherer-fisher developed standardized stone-built architectural features mostly built on or directly re...
Today, glaciers in the western Altiplano are very scarce, even on peaks exceeding 6,000 m. In this mostly ice-free landscape, however, moraines and other glacial deposits are commonly found attesting to quite different climate conditions that favored the advance of glaciers in the past. Although other areas of the Altiplano have been commonly accou...
The use of seaweed as fuel has been mentioned in ethnographic and historical sources of different coastal regions. Nevertheless, the archaeological record of seaweed burning is still limited to contexts where preservation is exceptional and macroscopic discrimination of charred remains is possible. Here, we evaluate the effectiveness of Raman spect...
The earliest European carvings, made of mammoth ivory, depict animals, humans, and anthropomorphs. They are found at Early Aurignacian sites of the Swabian Jura in Germany. Despite the wide geographical spread of the Aurignacian across Europe, these carvings have no contemporaneous counterparts. Here, we document a small, intriguing object, that sh...
Early inhabitants along the hyperarid coastal Atacama Desert in northern Chile developed resilience strategies over 12,000 years, allowing these communities to effectively adapt to this extreme environment, including the impact of giant earthquakes and tsunamis. Here, we provide geoarchaeological evidence revealing a major tsunamigenic earthquake t...
In this special issue, articles include research from Argentina, Brazil, Chile, Colombia, and Uruguay, plus a special paper from the United States of America. Several of the articles are from Chilean scientists and/or focus on Chilean geoarchaeology and are intended to reflect the spirit of the symposium carried out during the Congreso Nacional de...
Hunter‐gatherers’ architectural practices are one of the main topics to understand the entangled land use of these societies. In the hyperarid Atacama Desert coast (Northern Chile), hunter‐gatherers‐fishers developed standardized stone‐built architecture during the Late Archaic period (∼5,700–4,000 cal years BP), interpreted so far as sedentary vil...
El registro arqueológico lítico de superficie se encuentra expuesto a diversos agentes postdepositacionales, que desencadenan una serie de modificaciones que son parte de los procesos de formación de los conjuntos que hallamos. El estudio de estas modificaciones brinda información indispensable a la hora de proponer interpretaciones conductuales so...
Pleistocene deposits exposed along the coast of the Médoc area, south‑west France, represent valuable palaeoenvironmental archives that have been the subject of extensive work in the past few decades. To further understand the palaeoenvironmental history and sedimentary dynamics of these deposits, a detailed lithostratigraphic study was performed o...
One of the challenges commonly faced by Paleolithic archaeologists is disentangling archaeological layers in caves and rockshelters that often reflect complex palimpests. Layers defined in the field are primarly used to distinguish occupations, yet their actual nature and integrity are rarely tested or justified after excavation. Distinct occupatio...
A previously undocumented type of wetland is described from the Atacama Desert in northern Chile (3000 m above sea level), sustained exclusively by direct precipitation and perched above the regional water table. Geomorphological mapping, pedostratigraphy, geochemistry, and analysis of contemporary vegetation is used to understand wetland formation...
The palaeontological and archaeological records provide a unique window of opportunity for researchers seeking to investigate the response of wild animals and human populations to environmental change in the long-term. In this vein, the DeerPal project hopes to acquire new fundamental knowledge on the palaeoecology of animal communities faced with...
Dune pattern, grain-size gradients and geochemistry were used to investigate the sources and dynamics
of aeolian deposition during the last glacial in southwest France. The coversands form widespread fields
of low-amplitude ridges (zibars), whereas Younger Dryas parabolic dunes mainly concentrate in corridors
and along rivers. Spatial modelling of...
The recently discovered open-air site of Mirande 2 (Vaïssac, Tarn-et Garonne) lies on a gentle incline of the left bank of the Aveyron River approximately 100 metres from the site of Mirande 1 (Nègrepelisse, Tarn-et-Garonne), which was excavated between 1971 and 1976 by R. Guicharnaud. A test-pit carried out during rescue work evaluated the site’s...
The Land Use and Cover Area frame Statistical survey (LUCAS) database on topsoil properties in Europe was used to map aeolian deposits. The points which satisfy the grain-size criteria of coversands, loess and transitional facies were extracted from the rasters of predicted soil texture established by kriging of the LUCAS data by Ballabio et al. ()...
La partie centre-ouest du Bassin aquitain est caractérisée par une vaste couverture sableuse, aujourd'hui recouverte par la forêt des Landes de Gascogne. Cet espace correspond à un véritable erg sableux, dont la formation remonte au début du Quaternaire. Au cours du Tardiglaciaire, le Sable des Landes constitue déjà une grande unité naturelle au se...
Recent Laborian of the Peyrazet cave-rock shelter (Creysse, Lot, France). New data for the end of Lateglacial in Quercy.
Discovered in 1990, Peyrazet cave-rock shelter (Creysse, Lot) lies in the Haut-Quercy region at the limits of the Martel limestone plateau, several hundred meters from the current Dordogne River valley. Excavations begun in 2008...
Detailed stratigraphic analysis and numerical dating (OSL, IRSL, ESR, 14C) of Pleistocene coversands in southwest France enable the construction of a renewed chronostratigraphic framework for sand depo-sition. The chronological data obtained from sandsheet units testify to the development of transgressive dunefields since at least the Middle Pleist...
Numerous periglacial features (polygons, nets, soil stripes, ice-wedge pseudomorphs and sand-wedge casts, involutions) have been recorded in France by examining bibliographical sources and aerial photographs. These data show that a large part of France was affected by permafrost during the Pleistocene and only the southern Aquitaine Basin and Langu...
Quaternary aeolian deposits in the Aquitaine Basin (SW France) provide rare evidence of fossil periglacial aeolian systems located some distance from ice-sheet margins. Studying such systems sheds light on aeolian dynamics in a region which, during glacial periods, lay between the northern European zone with continuous permafrost and the permafrost...
The Shi’bat Dihya 1 site in western Yemen, dated by optically stimulated luminescence
to 55 ka, provides insight into the Middle Paleolithic peopling of
the Arabian Peninsula. The archaeological layer is interstratified within thick,
sandy silt floodplain deposits filling a piedmont basin. Luminescence dates, lack
of soil development, and gypsum pr...
The recovery at Shi’bat Dihya 1 (SD1) of a dense Middle Paleolithic human occupation dated to 55 ka BP
sheds new light on the role of the Arabian Peninsula at the time of the alleged expansion of modern
humans out of Africa. SD1 is part of a complex of Middle Paleolithic sites cut by the Wadi Surdud and
interstratified within an alluvial sedimentar...
Typologie morphologique et pétrographie des travertins plio-quaternaires du géosystème karstique de l'Oued Aggai (Causse de Sefrou, Moyen-At las, Maroc). Moussa K. et Boualla N. La sédimentation plio-quaternaire d'Oran (Ouest Algérie) : Aspects stratigraphiques et sédimentologiques. Géomorphologie, lithostratigraphie et sédimentologie des dépôts qu...
The lower terraces of the Dordogne River at Bergerac (south-west France) were studied in detail using cores, trenches, ground penetrating radar profiles, and 14C, optically stimulated luminescence and infrared stimulated luminescence dating. This study shows that the lowest terrace (Fx) is made up of two major lithostratigraphic units: (i) dominant...
The Arabian Peninsula has long been considered as a region devoid of long-term human settlement untilthe Holocene period, as a result of drastic climatic changes throughout the Pleistocene. It might beexpected that the area was deserted during hyper-arid and arid periods, and populated by new migrantgroups during humid events, according to a

During the last glacial period, a large part of the Aquitaine basin (southwest France) was a periglacial desert comprising coversands with low-relief dune fields surrounded by loess accumulations. OSL and radiocarbon dates show that the phase of maximum sand deposition coincides with Marine Isotope Stage (MIS) 2. Peats and gleyic palaeosoils interc...
