Mechanical fragmentation and thermal erosion of dyke adjacent host rocks induced by fluid-dynamic shear stress and latent heat release in response to turbulent magma flow
(2022)
We present a quantitative account of the thermodynamical and fluid-mechanical aspects of granitic host rock erosion related to dyke emplacement by considering the latent heat released from the dyke, subsequent thermal ...
Sheeted intrusion of granitic magmas in the upper crust – Emplacement and thermal evolution of the Guandacolinos pluton, NW Argentina
(Elsevier Science, 2021-10)
The Lower Carboniferous Guandacolinos pluton of northwestern Argentina (Western Sierras Pampeanas) preserves field, structural, and petrological evidence of sheet-like transport and assembly of granitic magmas in the upper ...
Petrography and metamorphism of the metasedimentary country-rocks of the Jacurici Valley Chromitite-Hosting mafic-ultramafic complexes, Bahia, Northeastern BrazilPetrography and metamorphism of the metasedimentary country-rocks of the Jacurici Valley Chromitite-Hosting mafic-ultramafic complexes, Bahia, Northeastern Brazil

Computational and experimental pore-scale studies of a carbonate rock sample
(2019-12-01)
Carbonate rocks host several large water and hydrocarbon reservoirs worldwide, some of them highly heterogeneous involving complex pore systems. Pre-salt reservoirs in the Santos Basin off the south-east coast of Brazil, ...
Estudo de rochas alcalinas intrusivas na região de Três Fontes - MG
(Universidade Estadual Paulista (Unesp), 2011)
Geological researches conducted in the past few years detected, through deep drill hole data, the presence of alkaline rocks in the region of Três Fontes-MG, where the Barbacena Group rocks, the Morro do Ferro Greenstone ...
Tourmaline orbicules in peraluminous monzogranites of Argentina: A study case of fluid-rock interaction between leucogranite and country-rock metasediments
(Pergamon-Elsevier Science Ltd, 2017-12)
Tourmaline orbicules hosted in peraluminous granites are documented worldwide. Seven occurrences were identified in Argentina. Petrography, mineral chemistry, whole-rock geochemistry mass balance and microthermometric ...
Hydrothermal eruptions at El Humazo, Domuyo geothermal field, Argentina: Insights into the eruptive dynamics and controls
(Elsevier Science, 2020-02)
Hydrothermal eruptions are explosive events driven by the sudden and violent vaporization of the water present in many hot water geothermal fields worldwide. Over recent years, thermodynamical conditions of fluids and ...
Intrusäo alcalina de Morro Preto (GO): Geologia, petrografia e geoquímica
(2014-01-01)
The alkaline intrusion of Morro Preto, located to the north of Piranhas (GO), Is an irregular to subcircular rock body with about 3,34 km2, hosted in gneisses of the Goiás Magmatic Arc. It is chiefly constituted by ...
The enigma of crustal zircons in upper-mantle rocks: Clues from the Tumut ophiolite, southeast Australia
(Geological Society of America, 2015)
We suggest a new explanation for the presence of crustally
derived zircons in the upper-mantle rocks of ophiolitic complexes,
as an alternative to subduction-related models. Integrated isotopic
(U-Pb, Hf, and O isotopes) ...
