In the recent geological past, Earth’s magnetic field reduced to ~10% of modern values and poles shifted away from geographic poles, causing Laschamps geomagnetic excursion, about 41 millennia ago. The excursion lasted ~2000 years, with dipole strength reduction tilting spanning 300 years. During this period, field’s multipolarity resembled outer planets, rapid magnetospheric changes. To our knowledge, study presents first space plasma analysis linking field, system, upper atmosphere in...
Abstract Northwestern Patagonia is located in a tectonically active part of the southern Andes (Argentina), which has facilitated formation obsidian, including pyroclastic deposits that have been affected by geomorphic processes, resulting complex obsidian landscape. To date, relocation landscape not focus systematic research, and this hampers our understanding prehistoric human mobility. We present an updated assessment regional availability different types based on results from research...
The importance of obsidian from the northern Patagonian source at Las Cargas is reflected in its early use (∼8000 years B.P.) and extensive geographic diffusion but nonetheless surprising light source's high altitude (located Andes Cordillera), which makes it both difficult to access under ideal conditions inaccessible for much year. Prehistoric can inform us about mobility, subsistence choices, economics stone consumption, trade, territoriality. Here we present results various lines...

Archaeology has much to contribute the study of cultural evolution. Empirical data at archaeological timescales are uniquely well suited tracking rates change, detecting phylogenetic signals among groups artefacts, and recognizing long-run effects distinct transmission mechanisms. Nonetheless, these still relatively infrequent subjects analysis archaeology's potential help advance our understanding evolution thus far been largely unrealized. Cultural evolutionary models developed in other...
Relative to other periods, there are very few recorded sites of middle Holocene age in Mendoza Province, Argentina. This analysis weighs the preliminary results a regional study against three possible explanations for small number sites: poor visibility, reduced population density and behavioural adaptation. While changes visibility cannot be dismissed, evidence suggests that scarcity mid-Holocene reflects changed patterns land resource use triggered by climate change. Archaeological data...
Nuestro objetivo es estudiar las estrategias de uso del espacio por parte sociedades humanas móviles en un paisaje andino Patagonia caracterizado una marcada heterogeneidad topográfica, climática y ecológica (localidad Barrancas-Buta Ranquil, provincia Neuquén, Argentina). Inicialmente, se analiza la estructura desde perspectiva biogeográfica, desarrollando modelo estacionalidad mediante sistemas información geográfica. enfoque distribucional combina prospección sistemática para caracterizar...
Abstract The obsidian dating method converts the quantity of diffused molecular water within a near‐surface hydration layer to elapsed time using an experimentally derived diffusion coefficient predicted from structural content glass. Infrared spectroscopic transmission measurements on transparent archaeological samples record vibrational responses bands in near‐infrared region, permitting determination (OH), and amount ambient (H 2 O). In this application, H O band at 5200 cm −1 is measured...
An assemblage of coarse volcanic rock (CVR) derived from the walls a rockshelter in Aisén, Chile was recently described as consisting bifaces, projectile points, and picks [Prentiss et al. 2015a. Lithic Technology 40:112–127]. The objects are not universally accepted cultural, however, on account both their crude appearance fact that CVR industries have been previously identified either valley where were found or elsewhere Patagonia. We present results three independent studies—a...
Obsidian is abundant in archaeological sites throughout Mendoza Province, Argentina but no obsidian hydration rates exist to date these assemblages.Direct dating of artifacts particularly important west-central because the surface record extensive well-defined time marker are lacking.The costs non-optical techniques currently preclude their regular use region, however.We present and evaluate 12 models for age estimation based on optical rim measurements two most commonly used types region...
