Late Cenozoic to modern-day volcanism in the Northern Andes: A geochronological, petrographical, and geochemical review
(Springer Verlag, 2019-01-01)
The Northern Andean Block is the result of complex tectonic interaction between the Farallon-Nazca, South American, and Caribbean Plates. Abundant late Cenozoic volcanism (and associated hypabyssal porphyritic plutonism), ...
Raman spectroscopy and x-ray fluorescence in molecular analysis of yellow blocks from the archeological site playa miller 7 (northern Chile)
(Sociedad Chilena de Quimica, 2013)
Yellow blocks from the archaeological site Playa Miller 7 (PLM7), on the coast of Atacama Desert in northern Chile, were analyzed by Raman spectroscopy and X-ray fluorescence (XRF) portable. Our results identify for the ...
Paleogeographie, structural and magmatic evidences for the existence of different lithospheric blocks in the Central Andes: samples from southern Peru and northern Chile
(IRD ÉditionsFRA, 2005)
The Andes are classically considered to represent the type of orogenie chains resulting from the subduction of an oceanic plate beneath a continental plate. In spite of a considerable literature invoJving stratigraphie, ...
Groundwater resources and recharge processes in the Western Andean Front of Central Chile
(ELSEVIER, 2020)
In Central Chile, the increment of withdrawals together with drought conditions has exposed the poor understanding of the regional hydrogeological system. In this study, we addressed theWestern Andean Front hydrogeology ...
Block rotations within the northern Peruvian Altiplano
(IRD ÉditionsFRA, 2008)
Counterclockwise tectonic rotations in the northern central Andes and clockwise rotations in the southern Central Andes have been systematically reported (see Roperch et al. 2006 and Arriagada et al., 2006 for a recent ...
Late Miocene garnet-bearing andesites in the Northern Andean Block and their tectonic implications
(Universidad EAFITGeologíaEscuela de Ciencias. Departamento de GeologíaMedellín, 2018)
Garnet-bearing volcanic rocks are rare at convergent margins, with few known occurrences worldwide. However, they are a common feature within the Late Miocene volcanic rock suite of the Northern Andean Block (NAB) along ...
Timing of rifting in the southern Gulf of California and its conjugate margins: Insights from the plutonic record
(Geological Society of America, 2015-05-01)
The Gulf of California is a young example of crustal stretching and transtensional shearing leading to the birth of a new oceanic basin at a formerly convergent margin. Previous studies focused along the southwestern rifted ...
Temperature and precipitation as predictors of species richness in northern andean amphibians from colombia
(Caldasia, 2013)
Our objective was to explore the spatial distribution patterns of amphibian speciesrichness in Antioquia, as model for the tropical Andes, and determine how annualmean temperature, annual precipitation, and elevation range ...
Andean caravan ceremonialism in the lowlands of the Atacama Desert: The Cruces de Molinos archaeological site, northern Chile
(2019)
Camelid caravans have played a key role in the complex systems of interregional social interaction that characterizes Andean history. In the northernmost region of Chile, the most frequent archaeological indicators of these ...
Unravelling the widening of the earliest Andean northern orogen: Maastrichtian to early Eocene intra-basinal deformation in the northern Eastern Cordillera of Colombia
(Wiley-Blackwell Publishing Ltd, 2020-07-21)
The onset of deformation in the northern Andes is overprinted by subsequent stages of basin deformation, complicating the examination of competing models illustrating potential location of earliest synorogenic basins and ...
