Delamination of southern Puna lithosphere revealed by body wave attenuation tomography
(American Geophysical Union, 2014-01)
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 ...
Velocity structure beneath the southern Puna plateau: evidence for delamination
(American Geophysical Union, 2013-10)
The high elevation of the southern Puna plateau, the widespread melting of its crust, the gap in intermediate depth seismicity and the recent eruptions of ignimbrite complexes can be explained by delamination of the ...
Thermal and geodynamic contributions to the elevation of the Altiplano-Puna plateau
(Elsevier Science, 2014-10)
The most remarkable feature of the Central Andes is the Altiplano–Puna plateau. This plateau is characterized by 3.5 km average elevation, approximately 70 km crustal thickness and very high heat flow. The upper mantle ...

Tectonic Evolution of the Central Andes: From Terrane Accretion to Crustal Delamination
(AAPG, 2018)
The analysis of the pre-Andean history of the Central Andes shows a complex tectonic evolution. The basement of the Andean continental margin was formed by the accretion of Precambrian blocks during the formation of Rodinia ...
Structure of the crust and the lithosphere beneath the southern Puna plateau from teleseismic receiver functions
(Elsevier Science, 2014-01)
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 ...
Structure of the crust and the lithosphere beneath the southern Puna plateau from teleseismic receiver functions
(Elsevier, 2014)
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 ...
Teleseismic tomography of the southern Puna plateau in Argentina and adjacent regions
(Elsevier Science, 2013-02)
An array of 74 seismological stations was deployed in the Argentine Puna and adjacent regions for a period of two years. The aim is to investigate the seismic structure in the crust and upper mantle in order to address ...
Pliocene intraplate-type volcanism in the Andean foreland at 26°10′S, 64°40′W (NW Argentina): Implications for magmatic and structural evolution of the Central Andes
(The Geological Society of America, 2010-05)
The Antilla magmatic complex (26°10′S, 64°40′W, NW Argentina) attests to magma eruption at ca. 4.7 Ma in the Central Andes backarc region, 300 km E of the active arc. The Antilla lavas have an alkaline, predominantly mafic ...
Estrutura do manto superior sob a Província Borborema através de tomografia telessísmica de onda P: implicações para o soerguimento, vulcanismo intraplaca e abertura do atlântico equatorial
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2018-02-28)
The Borborema Province is a geological and structural domain located in the Brazilian
Northeast, which is limited to the South by the São Francisco craton, to the West by the
Parna´ıba basin, and to the North and East ...
