AFC3D: A 3D graphical tool to model assimilation and fractional crystallization with and without recharge in the R environment
(Elsevier, 2014-03)
AFC3D is an original graphical free software developed in the framework of the R scientific environment and dedicated to the modeling of Assimilation and Fractional Crystallization without (AFC) and with (AFC-r) recharge, ...
Shear-assisted water-fluxed melting and AFC processes in the foreland of the Early Paleozoic Famatinian orogen: petrogenesis of leucogranites and pegmatites from the Sierras de Córdoba, Argentina
(Springer, 2021-10)
In the Comechingones pegmatitic field, central Argentina, leucogranite and pegmatite bodies crop out in a relatively narrow (25 × 10 km) belt, and were emplaced synkinematically with the main deformational event of the ...
Petrological and geochemical constraints on the magmatic evolution at the Ampato-Sabancaya compound volcano (Peru)
(Elsevier, 2023-09-23)
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, ...
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 ...
Magmatic differentiation at La Poruña scoria cone, Central Andes, northern Chile: Evidence for assimilation during turbulent ascent processes, and genetic links with mafic eruptions at adjacent San Pedro volcano
(Elsevier B.V., 2019)
La Poruña (21°53′S; 68°30′W) is a 140 m high scoria cone composed of pyroclastic material and an extensive basaltic-andesite to andesite lava flow that is up to 8 km in length. Automated mineralogical analysis describes a ...
Petrogenesis of peraluminous magmas in the Central Andean backarc: the Huayra Huasi Volcanic Complex, NW Argentina
(Springer, 2021-07)
The Huayra Huasi Volcanic Complex of Miocene age (11.88±0.15 Ma U–Pb zircon) was emplaced in the Northern Puna plateau of Argentina, spatially associated with ignimbrites erupted from Altiplano–Puna Volcanic Complex calderas. ...
Internal framework and geochemistry of the Carboniferous Huaco granite pluton, Sierra de Velasco, NW Argentina
(Servicio Nacional de Geología y Minería, 2018-03)
The A-type Huaco granite pluton of the Velasco range (Sierras Pampeanas of northwest Argentina) is formed by three coeval granitic facies and contains subordinate coeval-to-late facies, as well as enclaves, dikes and stocks ...
Ubinas: the evolution of the historically most active volcano in southern Peru
(Springer, 2005)
Ubinas volcano has had 23 degassing and ashfall episodes since A.D. 1550, making it the historically most active volcano in southern Peru. Based on fieldwork, on interpretation of aerial photographs and satellite images, ...
La Aguadita Trachyte: new exponent of Triassic alkaline magmatism in the Sierra de Valle Fértil, Western Sierras Pampeanas, Argentina
(2015)
La Aguadita Trachyte, in Sierra de Valle Fértil, is a new outcrop referring to the Triassic alkaline magmatism. The trachyte body was emplaced along a NNW-trending fault zone overlying the crystalline basement. The trachyte ...
