Late cenozoic tectonic and geomorphic evolution of the Patagonian Andes between 42oS and 52oS, southern Chile assessed using fission-track thermochronology. Fission-track FT analysis has been applied in the Patagonian Andes of southern Chile to assess the late Cenozoic geomorphic and tectonic response of the overriding plate to intermediw of the Chile rise active oceanic spreading centre Thomson et al.

The timing and nature of tectonic uplift and denudation along the southern parts of the major transpression intra-arc Contavilidad fault LOF system have also been investigated Thomson,submitted. Results from FT ages 72 zircon and 58 apatite ages and 39 apatite track length measurements reveal initiation of rapid cooling and denudation at ca. This was followed by a ca. East of the Andean divide less than 3 km of denudation has occurred since the Late Cretaceous.

Enhanced denudation inhermedia interpreted to be the result of increased tectonic uplift driven by a large increase in convergence rates at ca. The eastward migration of the locus of maximum denudation can be related to either coeval eastward migration of the retro-arc deformation front, the effects of subduction erosion in the overriding plate at the Peru- Chile trench or shallowing of the angle of subduction. Away from the influence of the LOF the process of spreading centre subduction and collision itself coincides with an overall slow-down in denudation rates in the overriding plate most likely caused by a major reduction in the main tectonic force driving tectonic uplift in the upper plate to subduction.

In contrast to the Andes south of ca. The Quaternary calc-alkaline volcanism of the Patagonian Andes close to the Chile triple junction: Cay and Maca are two large, adjacent stratovolcanoes that rise from the Chiloe block at the southern end of the southern volcanic zone SVZ of the Andes.

Samples from the two volcanoes are typical medium-K, calc-alkaline rocks that form two roughly continuous, largely overlapping series from subalkaline basalt to dacite. The overall geochemistry of the samples studied is very similar to that observed for most volcanoes from the southern SVZ. This is in accordance with the thin Maca magmas is investigated by means of the relative concentration of fluid mobile e. Ba and fluid immobile e. Nb, Ta, Zr, Y elements and other relevant trace-element ratios e.

The results indicate that small amounts Maca volcanoes and that, despite the very young age Maca magma sources to varags northern edge of the slab window generated by the subduction of the Chile ridge under the South American plate, we did not find any geochemical evidence for u contribution of a subslab asthenospheric mantle. However, this mantle has been used to explain the peculiar geochemical features e. Complex brittle deformation pattern along the Southern Patagonian Andes Argentina.

The Southern Patagonian Andes is located in the southern extreme of the Pacific subduction zone, where the Antartic oceanic plate sinks underneath South America. The history of the area begins with compression during Paleozoic, Jurassic extension associated to the rift and opening of the South Atlantic Ocean, then a sag stage in the Lower Cretaceous followed by a foreland phase as a result of plate tectonics Ghiglione et al. We measured around fault planes and their striaes with the sense of movement in order to characterize the stress field.

The stress field map was built with the results of the MIM. We present new data from 48 sites located in the northern sector of the Southern Patagonian Andes.

The measurements were made in several rocks from Paleozoic to Lower Cretaceous, even though most were taken in pyroclastic jurassic rocks from El Quemado Complex. The pattern of faults found is complex. In some sites the tensor can be locally vaegas to satellite images and observations from the field or be related to a major thrust front.

Probably there are several generations of family faults connected to different and recent tectonic phases then the paleostress tensors might correspond to the latest tectonic events. Glacial lakes of the Central and Patagonian Andes. Wilson, Ryan; Glasser, Neil F. The prevalence and increased frequency of high-magnitude Intemredia Lake Outburst Floods GLOFs in the Chilean and Argentinean Andes suggests this region will be prone to similar events in the future as glaciers continue to retreat and thin under a warming climate.

Despite this situation, monitoring of glacial lake development in this region has been limited, with past investigations only covering relatively small regions of Patagonia.

This study presents new glacial lake inventories forandcovering the Central AndesNorthern Patagonia and Southern Patagonia.

Our aim was to characterise the physical attributes, spatial distribution and temporal development of glacial lakes in these three sub-regions using Landsat satellite imagery and image datasets available in Google Earth and Bing Maps. Glacial lake water volume was also estimated using an empirical area-volume scaling approach.

Such changes equate to a glacial lake water volume increase of 65 km3 during the year observation period. However, glacial lake growth and emergence was shown to vary sub-regionally according to localised topography, meteorology, climate change, rate of glacier change and the availability of low gradient ice areas.

These and other factors are likely to influence the occurrence of GLOFs in the future. This analysis represents the first large-scale census of glacial lakes in Chile and Argentina and will allow for a better understanding of lake development in this region, as well as, providing a basis for future GLOF risk assessments.

Andes virus infections in the rodent reservoir and in humans vary across contrasting landscapes in Chile. Hantavirus cardiopulmonary syndrome HCPS is an emerging infectious disease first reported in Chile in To determine whether the reservoir rodent Oligoryzomys longicaudatus populations are also geographically segregated, we conducted range-wide spatial vatgas analyses of O.

Given that landscape structure influences the incidence of hantavirus infections, we also tested Bisch. Population genetic analyses of O. Significant differences in the relative prevalence of anti-ANDV antibodies in rodent samples also were found across the three ecoregions.

We relate these results to the number of reported human HCPS cases in Chileand discuss the importance of landscape differences in light of ANDV transmission to humans and among rodent populations.

Impact of glaciations on the long-term erosion in Southern Patagonian Andes. The Southern Patagonian Andes are an ideal setting to study the impact of Late-Cenozoic climate cooling and onset of glaciations impact on the erosional history of mountain belts.

Moreover, the glaciations history of Patagonia shows the best-preserved records within the southern hemisphere with the exception of Antarctica. Indeed, the dry climate on the leeward side of Patagonia and the presence of lava flows interbedded with glacial deposits has allowed intermwdia exceptional boch of late Cenozoic moraines with precise dating using K-Ar analyses on lava flow.

The chronology of moraines reveals a long history covering all the Quaternary, Pliocene, and up to the Upper Miocene. In order to quantify the erosion history of the Southern Patagonian Andes and compare it to the glaciations sediment record, we collected samples along an age-elevation profile for low-temperature thermochronology in the eastern side of the mountain belt Torres del Paine massif. We used inverse procedure predicting 4He distributions within an apatite grain using a radiation-damage and annealing model to quantify He-diffusion kinetics in apatite.

The model also allows quantifying the impact of potential U-Th zonation throughout each apatite crystal. Geochronologically, Rapela and Kay had distinguished Early Cretaceous to Ma and Late Cretaceous to 75 Ma magmatic episodes based in potassium-argon data.

For the granitic rocks of the area of Paso Icalma, Moquehue and the Rahue granodiorites, Cingolani et al. Structural control on arc volcanism: This paper describes the volcanostratigraphy, structure, and tectonic implications of an arc volcanic complex in an oblique subduction setting: The CAC is located in a first-order morphotectonic transitional zone, between the low and narrow Patagonian and the high and broad Central Andes.

Magma ascent has occurred along planes perpendicular to the least principal horizontal stress, whereas hydrothermal activity and hot springs also occur along parallel planes. At a local scale within the CAC, effusions are controlled by local structures that formed at the intersection of regional fault systems.

Spring northward juvenile migration of the Patagonian grenadier Macruronus magellanicus from the Northwest Patagonian waters of Chile. Directory of Open Access Journals Sweden. Generalized linear model was used to describe the presence of juvenile per latitude and depth, and to infer the origin and displacement of juveniles.

Subsequently, LFD data were grouped according to latitudinal strata. Grouped LFD were decomposed into normal component groups, from which mean, standard deviation and proportion were estimated from the mixed LFD. The average length of the identified groups were sorted from south to north, and intermevia to compute significant increment in fish length and age per kilometers. The length increment per time was not due to growth, rather they was due to spatial displacement of juvenile from southern nursery grounds to northern feeding areas.

The West Wind Drift Current seems to be the main drive for dispersion of Patagonian grenadier to recruit northward in open waters along the continental shelf. Transboundary protected area proposals along the Southern Andes infermedia Chile and Argentina: Status of current efforts.

An evolving network of protected areas along the southern Andes of Chile and Argentina-the heart of Patagonia-are in various stages of evaluation and potential Transboundary Protected Area designations.

This paper examines three such efforts. The first proposal is the North Andean-Patagonia Regional Eco-Corridor, which was the subject of a recent bilateral meeting Black carbon and other light-absorbing impurities in the Andes of Northern Chile. Black carbon BC and other light-absorbing impurities in snow absorb solar radiation and thus have the potential to accelerate glacial retreat and snowmelt.

In Chileglaciers and seasonal snow are important sources of water for irrigation and domestic uses. In July Austral winter we sampled snow in the western Andes in a north-south transect of Chile from 18 S to 34 S. Most of the sampled snow had fallen during a single synoptic event, during July.

The snow was melted and passed through 0.

Preliminary estimates indicate that 1 the ratio of BC to dust in snow increases going south from Northern to Central Chileand 2 in snow sampled during the two weeks following the snowstorm, the impurities were concentrated in the upper 5 cm of snow, indicating that the surface layer became polluted over time by dry deposition.

Ecology, genetic diversity, and phylogeographic structure of andes virus in humans and rodents in Chile. In this study, we found seropositive rodents further north in the Coquimbo region 30 degrees S in Chile.

Rodent seroprevalence was 1. Human and rodent samples grouped according to geographic location. Phylogenetic comparative analyses of portions of S and medium segments encoding glycoproteins Gn and Gc from a subset of rodent specimens exhibited similar topologies, corroborating two major ANDV Sout clades in Chile and suggesting that yet unknown factors influence viral gene flow and persistence throughout the two Chilean ecoregions.

Genetic algorithms for recombination detection identified recombination events within the S segment. Molecular demographic analyses showed that the virus is undergoing purifying selection and demonstrated a recent exponential growth in the effective contabiildad of ANDV Sout infections in Chile that correlates with ijtermedia increased number of human cases reported.

Although we determined virus sequences from four rodent species, our results confirmed O. Hydrological response in catchments whit debris covered glaciers in the semi-arid AndesChile.

Glaciers in the semi-arid Andes Cordillera in Chile have shrank rapidly during the 20th century. Negative mass balance contributes to increase the surface area of vartas glaciers. Recent research in Chile suggests that contributions from glaciers to summer season river flow in dry years is very important, however hydrological processes determining the glacier contribution are still poorly understood in the region.

This work seeks to determine appropriate parameters for the simulation of melt volume in two watersheds dominated interemdia debris-covered glaciers, in g to understand ijtermedia variability in time and space, in the area with the largest population in Chile. The hydrometeorological records necessary model runs have been collected through fieldwork from to The results have allowed to know the relevance of the glacier contribution to mountain streams, allowing to know the calibration parameters most relevant in the hydrology balance of glacier basins in the Andes.

This particular structural system has not been fully addressed in terms of the age and mechanisms that built this orogenic segment. Here, new field and seismic evidence of syntectonic strata constrain the timing of the main deformational stages, evaluating the prevailing crustal regime for the different mountain domains through time.
