Synthesis: PLUTONS: Investigating the relationship between pluton growth and volcanism in the Central Andes
(Geological Society of America, 2018-06)
The Central Andes is a key global location to study the enigmatic relation between volcanism and plutonism because it has been the site of large ignimbrite-forming eruptions during the past several million years and currently ...
Ushuaia pluton: Magma diversification, emplacement and relation with regional tectonics in the southernmost Andes
(Pergamon-Elsevier Science Ltd, 2018-12)
The Ushuaia pluton (UP) and the Ushuaia Peninsula Andesites (UPA) are intrusive units of a Late Cretaceous rear-arc in the Southernmost Andes. We report new LA-ICP-MS zircon ages from ∼71 to 75 Ma for the UP, and of ∼84 ...
Contrasting magmatic structures between small plutons and batholiths emplaced at shallow crustal level (Sierras de Córdoba, Argentina)
(Pergamon-Elsevier Science Ltd, 2016-11)
Processes like injection, magma flow and differentiation and influence of the regional strain field are here described and contrasted to shed light on their role in the formation of small plutons and large batholiths their ...
U-Pb ages and Hf isotope compositions of zircons in plutonic rocks from the central Famatinian arc, Argentina
(Pergamon-Elsevier Science Ltd, 2017-07)
The Famatinian arc formed around the South Iapetus rim during the Ordovician, when oceanic lithosphere subducted beneath the West Gondwana margin. We present combined in situ U–Th–Pb and Lu–Hf isotope analyses for zircon ...
Thermal modeling of pluton emplacement and associated contact metamorphism:parashi stock emplacement in the serranía de jarara (alta guajira, colombia)
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2010)
In the northernmost portion of the Serrania de Jarara (Alta Guajira, Colombia), low - medium grade metamorphic rocks from the Etpana Metamorphic Suite were thermally affected by emplacement of a small calc-alkaline intrusion ...
Space-time relation of post-collisional granitic magmatism in Santa Catarina, southern Brazil: U-Pb LA-MC-ICP-MS zircon geochronology of coeval mafic-felsic magmatism related to the Major Gercino Shear Zone
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
LA-MC-ICP-MS U-Pb zircon dating was performed on syntectonic, early post-collisional granitic and associated mafic rocks that are intrusive in the Brusque Metamorphic Complex and in the Florianopolis Batholith, major ...
