We present a teleseismic P and S receiver function study using data from a temporary passive-source seismic array in the southernmost Puna plateau and adjacent regions. The P receiver function images show the distribution ...

The southern Puna Plateau has been proposed to result from a major Pliocene delamination event that has previously been inferred from geochemical, geological, and some preliminary geophysical data. Seventy-five seismic ...

There is scarce documentation of the presence of trout in the Puna and southern Altiplano in Chile, in spite of the risk that they represent for these ecosystems of high environmental value, which have endemic and highly ...

We performed a teleseismic P wave tomography study using seismic events at both teleseismic and regional distances, recorded by a temporary seismic array in the Argentine Puna Plateau and adjacent regions. The tomographic ...

This paper describes a large obsidian deposit located along the southern banks of Laguna Blanca, on the eastern slope of the Jarellón volcanic caldera near the Chilean–Bolivian border. The obsidian at this site occurs ...

During two field campaigns in 2007 and 2010, long-period and broadband magnetotelluric measurements were conducted in the Central Andes of northern Chile and northwestern Argentina at a latitude of 23.7°S. The study area ...

The Central Andes is a key global location to study the enigmatic relation between volcanism and plutonism because it has been the site of large ignimbrite-forming eruptions during the past several million years and currently ...

Se presenta un estudio funcional de los instrumentos de toba del sitio Tulán-54, asentamiento de carácter ceremonial del periodo Formativo Temprano (ca. 3500 - 1500 cal. AP) ubicado en Quebrada Tulán, al sur de la cuenca ...

Palaeoindian occupation of the Atacama Desert in northern Chile has been found between 12 600 and 10 200 cal. yr BP. The new site at Salar Punta Negra (24 280S/60 530W/ 2976 m) includes about 1000 classifiable, mostly ...

Phylogenetic diversity (PD) is commonly calculated by adding together the branch lengths or ages of a subset of taxa present in an area, using a single phylogeny as a backbone. However, a phylogenetic hypothesis is the ...
