“…The new averages for AMS ages only from lake and surface deposits are both somewhat older than the most recent previously published age estimate for the H1 eruption of 6,890±100 14 C yrs BP (median probability age 7,698 cal yrs BP; Stern, 2008;Prieto et al, 2013), which was based dominantly on conventional radiocarbon ages for samples from bog deposits. Although the total range of the different AMS ages from lakes and bogs compared to the conventional ages from bogs are overall relatively FIG.…”

“…The AMS ages from these three surface deposits, and other surface deposits in Patagonia, are systematically lower than the ages from the lake cores, with minimum ages ranging from 6,755±40 to 7,176±19 14 C yrs BP, maximum ages from 6,750±25 to 7,410±25 14 C yrs BP, and an average age of 7,084±23 14 C yrs BP (median probability age: 7,891 cal yrs BP; Table 2). Although this average is older than the average obtained in the previous most recent compilation of H1 ages (6,890 14 C yrs BP; Prieto et al, 2013), this new compilation includes only AMS radiocarbon ages (Table 2) and not any conventional ages. The <200 year difference between the average of these new AMS ages and the previous compilation of conventional ages is nevertheless consistent with these tephra having been generated by the H1 eruption of Hudson.…”

“…small (<700 years or <10% of the approximate >8,000 cal year BP age for H1), further refinements of the age of the H1 eruption is of interest, since this was the largest Holocene eruption in the southern Andes during the Holocene (Stern, 1991(Stern, , 2004(Stern, , 2008Naranjo and Stern, 1998), and it produced a widely distributed tephra layer that has been used as a chronologic marker for numerous paleoclimate (Waldmann et al, 2009;Unkel et al, 2010;Borromei et al, 2010;Bjork et al, 2012;Villa-Martínez et al, 2012;Menounos et al, 2013) and archaeological studies (Prieto et al, 2013) in southern Patagonia.…”

ABSTRACT. Two Holocene tephras encountered in outcrops, cores and trenches in bogs, and lake cores in the area around Cochrane, southern Chile, are identified (based on their age, tephra glass color and morphology, mineralogy, and both bulk and glass chemistry) as H1 derived from Hudson volcano, and MEN1 derived from Mentolat volcano. New AMS radiocarbon ages indicate systematic differences between those determined in lake cores (MEN1=7,689 and H1=8,440 cal yrs BP) and surface deposits (MEN1=7,471 and H1=7,891 cal yrs BP), with the lake cores being somewhat older. H1 tephra layers range from 8 to 18 cm thick, suggesting that both the area of the 10 cm isopach and the volume of this eruption were larger than previously suggested, but not greatly, and that the direction of maximum dispersion was more to the south. MEN1 tephra layers range from 1-4 cm in thickness, indicating that this was probably a reasonably large (>5 km 3 ) eruption. Some of the lake cores also contain thin layers (<2 cm) of late Holocene H2 tephra and the recent H3 (1991 AD) tephra, both derived from the Hudson volcano. No tephra evidence has been observed for any late Pleistocene tephra, nor for the existence of the supposed Arenales volcano, proposed to be located west of Cochrane. Keywords: Tephra, Tephrochronology, Volcanism, Hudson, Mentolat, Andes, Chile. RESUMEN. Tefrocronología holocénica cerca de Cochrane (~47° S), Chile Austral. Dos tefras holocenas reconocidas en af loramientos, testigos y trincheras en pantanos y lagos de la zona de Cochrane, Chile, han sido identificadas (sobre la base de su edad, color y morfología de las partículas vítreas, mineralogía y composición química de la roca total y del vidrio) como H1 y MEN1, provenientes de los volcanes Hudson y Mentolat, respectivamente. Nuevas edades radiocarbónicas AMS asociadas a estas tefras revelan diferencias sistemáticas entre los testigos lacustres (MEN1=7,689 y H1=8,440 años cal. AP) y los depósitos en superficie (MEN1=7,471 y H1=7,891 años cal. AP), en que las edades en los testigos lacustres son algo más antiguas. Los horizontes de la tefra H1 varían entre 8 y 18 cm de espesor, lo que indicaría que tanto el área de la isópaca de 10 cm como el volumen de esta erupción fue levemente mayor a lo previamente reconocido, y que la dirección de dispersión fue más hacia el sur. Los niveles de la tefra MEN1 varían entre 1 y 4 cm de espesor, lo que sugiere que esta fue una erupción relativamente grande (>5km 3 ). Algunos testigos lacustres también incluyen niveles más finos (<2 cm) de otra tefra (H2) del Holoceno tardío y de la tefra (H3) asociada a la erupción del año 1991, ambas derivadas del volcán Hudson. No se encontraron evidencias de tefras pleistocénicas tardías ni tampoco de la presencia del volcán Arenales, supuestamente ubicado al oeste de Cochrane y cuya existencia ha sido puesta en duda.

“…Los estudios arqueológicos han mostrado un proceso de adaptación a los recursos marinos a partir de poblaciones cazadores-recolectores terrestres (Legoupil & Fontugne, 1997;Orquera & Piana, 2005;Orquera et al 2011;Piana & Orquera, 2009) que podrían haberse desencadenado a consecuencia de la erupción del volcán Hudson hace unos 7750 años (Prieto et al 2013). Este origen autóctono de la adaptación de los canoeros fueguinos, junto con las similitudes craneométricas y moleculares citadas, resultan compatibles con un modelo de origen único holocénico del poblamiento de la Tierra del Fuego.…”

RESUMENCon el objetivo de contribuir al conocimiento sistemático de la antropología biológica de las etnias fueguinas se ha reunido la información existente sobre sus características dermatoglíficas. Han sido revisados tres trabajos que presentan los resultados individuales de 81 manos (14 yámana, 54 kawésqar y 13 selk'nam), y se ha creado una base de datos para compararlos con otras poblaciones de América. Los fueguinos se sitúan claramente entre las poblaciones indígenas americanas en el contexto de la variación mundial de los dermatoglifos, pero con un perfil propio diferenciado.PALABRAS CLAVE: Antropología biológica, dermatoglifos, Tierra del Fuego, América. RESEARCH ON FUEGUIAN DERMATOGLYPHICS ABSTRACTIn order to contribute to the systematic knowledge of the biological anthropology of the Fueguian ethnic groups, the existing information on their dermatoglyphic features has been assembled. Three papers showing the individual results of 81 hands (14 yámana, 54 kawésqar and 13 selk'nam) have been found, and a database has been created for comparisons with other populations of the Americas. From a global perspective on the dermatoglyphic variations, the peoples of Tierra del Fuego are clearly situated among the Native American populations, but have an own distinct profile.

Objectives: Artificial deformation of the cranium in humans has been related to powerful environmental-cultural stimuli that modify vectors of growth and development when the cranium is still malleable. Osteological differentiation into deformed and nondeformed remains enables the morphological information of individuals that make up ethnic groups or populations to be separately contrasted, the invariant measurements of deformation to be identified, the information provided by archeological remains to be placed in a social context, the cranial variation to be related to genetic variation (individuals without deformation), and predictions to be made (in the absence of direct genetic information). Methods: With samples of reduced size and many variables, we propose a decision rule based on: (a) pre-selecting variables (Kruskal-Wallis and Λ-Wilks test); (b) applying logistic regression to obtain the optimal classification criterion; and (c) defining a multi-criterion decision rule to bring about greater robustness. Results: After applying the decision rule to a sample of 180 crania (71 from the Selknam, 74 from the Yamana, and 35 from the Alakaluf ethnic groups), it was possible to identify the Selknam men with frontal deformation and the Yamana women with flattening of the parietal regions at the height of the bregma. Conclusions: From there on with the information provided by the graphical representation of the populations in the most informative dimensions and the homogeneity contrast between sexes, we related the frontal deformation in Selknam men to dragging firewood, vegetable matter, domestic utensils, and heavy pieces of meat from the hunt. On the other hand, the flattening of the parietal areas at the height of the bregma in Yamana women is related to loading and transporting vegetables and animals in baskets or leather sacks.
