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, ...

Thermal maturation of a complete magmatic plumbing system at the Sierra de Velasco, Northwestern Argentina
(Cambridge University Press, 2020-06-16)
The formation of magmatic plumbing systems in the crust involves mass and heat transfer from deep to shallow levels. This process modifies the local geotherm and increases the thermal maturation of the crust, affecting the ...
Magma Chamber Associated to Deep Faults in Copahue Active Volcanic Complex, South America, Suggested by Magnetotelluric Study
(National Academy of Sciences of Ukraine. Subbotin Institute of Geophysics, 2018-08)
Magnetotelluric studies were carried out in 1993 and 2008 inside the caldera of Copahue Volcanic Complex, located in South America, at the border between Chile and Argentina (37°45ʹ S; 71°10.2ʹ W). The main effusive centre ...
Geochemistry of Mercury Along a Soil Profile Compared to Other Elements and to the Parental Rock: Evidence of External Input

Evolução do rifteamento e paleogeografia da margem Atlântica Equatorial do Brasil: Triássico ao Holoceno
(2011-12-01)
The Equatorial Atlantic Margin evolved from three rift systems recorded by a complex set of sedimentary basins developed since Upper Triassic to the Lower Cretaceous (Albian). The first rift system formed Foz do Amazonas ...

Tectonothermal evolution and exhumation history of the Paleozoic Proto-Andean Gondwana margin crust: the Famatinian Belt in NW Argentina
(Elsevier Science, 2011-09)
We studied the P-T-t evolution of a mid-crustal igneous-metamorphic segment of the Famatinian Belt in the eastern sector of the Sierra de Velasco during its exhumation to the upper crust. Thermobarometrical and geochronological ...
