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 ...
Geophysical modeling and structure of Ushuaia Pluton, Fuegian Andes, Argentina
(Elsevier Science, 2009-10)
Within the area of Ushuaia Bay (Tierra del Fuego, southernmost South America) the deformed Lower Cretaceous sedimentary rocks of Yahgán Formation host the Ushuaia Pluton. The intrusive body is oval in map view; it is ...
Compositional zonation of the shallow La Gloria pluton (Central Chile) by late-stage extraction/redistribution of residual melts by channelization: Numerical modeling
(Elsevier, 2017)
The origin of highly evolved magmas (e.g. rhyolites) has been a long-standing controversy in earth sciences. They
are commonly thought to be generated in the upper crust by melt extraction from mush zones, but due to ...
Brasiliano-age granitoids in the Sergipana Fold Belt, NE Brazil: the Coronel João Sá Pluton
(1998)
The Coronel João Sá pluton is a zoned Brasiliano-age, late- to post-tectonic intrusion in the Macururé schist domain of the Sergipana Foldbelt, Northeast Brazil. Biotite-hornblende granodiorite predominates, and flattened ...
Control estructural sobre el plutón los ratones y la mineralización de uranio en la Sierra de Fiambalá, Sierras Pampeanas, CatamarcaStructural control on the Los Ratones pluton and the uranium mineralization at the Fiambalá range, Sierras Pampeanas, Catamarca
(Asociación Geológica Argentina, 2010-12)
El Granito Los Ratones, de edad carbonífera, está compuesto por dos facies principales: porfírica y equigranular. La mineralización de uranio alojada en la caja metamórfica sobre el borde NO del plutón se interpreta asociada ...
Magnetic fabric and zircon U-Pb geochronology of the Itaoca pluton: Implications for the Brasiliano deformation of the southern Ribeira Belt (SE Brazil)
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The Itaoca pluton consists of porphyritic monzogranite that intruded the upper crust into low-grade metasedimentary rocks of the Apiai Dornain (Ribeira Belt). Anisotropy of magnetic susceptibility and zircon U-Pb (Shrimp) ...
Petrologia do magmatismo tardi-brasiliano no Maciço São José de Campestre(RN/PB), com ênfase no Plúton Alcalino Caxexa
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2000-03-24)
The area studied is located on the north-easternmost portion of the Borborema Province, on the so-called São José de Campestre Massif, States of RN and PB, Northeast Brazil. Field relations and petrographic, geochemical ...
Magnetic susceptibility mapping of the Cambrian El Hongo pluton, Eastern Sierras Pampeanas, Argentina
(Springer, 2017-04)
A map of bulk magnetic susceptibility was obtained on El Hongo trondhjemite, a small Cambrian pluton intruding the metamorphic basement in Eastern Sierras Pampeanas, Argentina, based on systematic magnetic susceptibility ...
Incremental growth of an upper crustal, A-type pluton, Argentina: Evidence of a re-used magma pathway
(Elsevier Science, 2017-07)
Carboniferous igneous activity in the Sierra de Velasco (NW Argentina) led to the emplacement of several magmas bodies at shallow levels (< 2 kbar). One of these, the San Blas intrusive complex formed over millions of years ...
Geology, petrology and geochronology of sierra Valle Fertil - La Huerta batholith: Implications for the construction of a middle-crust magmatic-arc section
(Elsevier, 2020)
The Valle Fertil-La Huerta batholith is a differentially tilted, compositionally stacked, calc-alkaline plutonic sequence in the central Famatinian arc of Argentina. It consists of two major lithologic units: these are (1) ...
