(Elsevier Ltd, 2019)This paper has been written following the results and reflections of the previously published paper (Viguier et al., 2018) detailing a multidisciplinary assessment of the groundwater resources in the northern part of the ...
-
(American Meteorological Society, 2016)The climatology and recent trends of low-level coastal clouds at three sites along the northern Chilean coast (18.3 degrees-23.4 degrees S) are documented based upon up to 45 years of hourly observations of cloud type, ...
-
(2012)In April 2009, at the Salar de Punta Negra (24°35'S, 68°58'W) in the Antofagasta Region of northern Chile, we quantified the composition, diversity, and size of diatoms, the only consumed prey by both adults and nestlings ...
-
(Universidad Católica del Norte, 2015)This study is a reassessment of the chronological and cultural sequence of the Archaic Period in Taltal, in an attempt to document the continuities and transformations in the economic organization of local populations who ...
-
(Elsevier, 2018)Seismic rupture of the shallow plate-boundary can result in large tsunamis with tragic socio-economic consequences, as exemplified by the 2011 Tohoku-Oki earthquake. To better understand the processes involved in shallow ...
-
(Nature Research, 2021)The subduction of oceanic plates beneath continental lithosphere is responsible for continental growth and recycling of oceanic crust, promoting the formation of Cordilleran arcs. However, the processes that control the ...
-
Fe–O stable isotope pairs elucidate a high-temperature origin of Chilean iron oxide-apatite deposits (Elsevier, 2016)Iron oxide–apatite (IOA) ore deposits occur globally and can host millions to billions of tons of Fe in addition to economic reserves of other metals such as rare earth elements, which are critical for the expected growth ...
-
(2009)Petrographic analysis and geochemical characterization studies were carried out on vitreous dacite and/or rhyodacite artefacts from Formative period archaeological sites in the upper Salado River Basin in the Atacama Desert, ...
-
(Elsevier, 2017)In this paper we present an overview of the process of mapping and field surveying of an area of ancient fields and irrigation canals around the pre-Hispanic sites of Topaín, Paniri and Turi, in the Andean highlands of ...
-
(Taylor & Francis, 2017)The high Andes of western South America feature extreme ecological conditions that impose important physiological constraints on humans including high-elevation hypoxia and cold stress. This leads to questions regarding ...
-
(2002)Endemic taxa are those restricted to a specific area, and could be defined as the exclusive biodiversity of a region. An area of endemism contains taxa found nowhere else and could be catalogued as irreplaceable and of ...

(Universidad Católica del Norte, 2017)Este artículo busca contribuir al estudio de la circulación humana en los espacios internodales, investigando lugares de uso pasajero en zonas áridas o semi áridas. La investigación se concentra en una específica localidad: ...
-
(2006)Plant macrofossils from 33 rodent middens sampled at three sites between 2910 and 3150 m elevation in the main canyon of the Río Salado, northern Chile, yield a unique record of vegetation and climate over the past 22,000 ...
-
(University of Oxford, 2015)In this paper, we focus on the study of metal objects associated with populations living on the northern coast of Chile in the Late Intermediate and Late periods (c. ad 1000-1550). Our contribution is based on morphometric ...
-
(Interciencia, 2015)This paper reports on an unknown yellowish mineral compound found in an archaeological context from Chorrillos cemetery (Calama, Chile) dating to the Early Formative period (800 - 200 B.C.). We used optic microscopy, SEM, ...
-
(Elsevier, 2018)Iron oxide-apatite (IOA) or Kiruna-type deposits are an important source of iron and other elements including REE, U, Ag, and Co. The genesis of these deposits remains controversial, with models that range from a purely ...
-
(Elsevier, 2015)New paleomagnetic data from Permo-Triassic and Late Cretaceous rocks yield a consistent trend of vertical-axis-tectonic-rotations which are consistent with the Central Andean Rotation Pattern (CARP). However, three sites ...
-
(Public Library Science, 2020)Extreme arid conditions in the Atacama Desert in northern Chile have created a unique vegetation almost entirely restricted to the desert margins along the coast of the Pacific Ocean and the Andean range. In this study we ...
