Petrology of the Miocene igneous rocks in the Altar region, main Cordillera of San Juan, Argentina: A geodynamic model within the context of the Andean flat-slab segment and metallogenesis
(Pergamon-Elsevier Science Ltd, 2011-07)
The Altar porphyry Cue(AueMo) deposit (31 290 S, 70 280 W) is located in the Andean Main Cordillera of San Juan Province (Argentina), in the southern portion of the flat-slab segment (28e33 S), 25 km north of the world-class ...
The influence of variations in crustal composition and lithospheric strength on the evolution of deformation processes in the southern Central Andes: insights from geodynamic models
(Springer, 2021-02)
Deformation in the orogen-foreland system of the southern Central Andes between 33° and 36° S varies in style, locus, and amount of shortening. The controls that determine these spatially variable characteristics have ...
Análise de terrenos na porção setentrional da Província Borborema, NE do Brasil: integração de dados geológicos e gravimétricos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 1999-08-20)
It is presently assumed that the Borborema Province resulted from a complex collisional process associated with the convergent movement of plates, possibly involving amalgamation and accretion of microplates. This process ...
Inversão simultânea de função do receptor e dispersão de ondas de superfície na Bacia do Pantanal
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2019-07-30)
The lithospheric structure of the South American continent has been mainly investigated
through continental-scale seismic studies and a number of seismic experiments in the
Andean region. As a result, there is still a ...
Evolution of the Taupo Volcanic Center, New Zealand: petrological and thermal constraints from the Omega dacite
(Springer, 2013)
The 20 ka *0.1 km3 Omega dacite, which
erupted shortly after the 26.5 ka Oruanui super-eruption,
compositionally stands out among Taupo Volcanic Zone
(TVZ) magmas, which are overwhelmingly characterized
by rhyolites ...
Magma chamber growth models in the upper crust: A review of the hydraulic and inertial constraints
(Elsevier B.V., 2019-05)
Finite volumes of magma moving in confinement, store hydraulic potential energy for the generation, control and transmission of power. The Pascal´s principle in a hydraulic jack arrangement is used to model the vertical ...
Petrological and geochemical constraints on the magmatic evolution at the Ampato-Sabancaya compound volcano (Peru)
(ElsevierNL, 2023-11)
In order to gain insights into continental arc magmatic processes, we have conducted a petrological and geochemical study of major and trace elements and Sr, Nd, and Pb isotopes of the Ampato-Sabancaya compound volcano, ...
