Magmatism in the Central Andes
(Mineralogical Society of AmericaUS, 2018-08)
Active continental margins are shaped by subduction-related magmatism, and the Central Andes of South America are a prime example. The Central Andean orogen has evolved over the past 25 My via magmas ascending from the ...
Magmatic Epidote and Amphibole from the Rio Espinharas Hybrid Complex, Northeastern BrazilMagmatic Epidote and Amphibole from the Rio Espinharas Hybrid Complex, Northeastern Brazil
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2005)
The relation of the mid-Tertiary coastal magmatic belt in south-central Chile to the late Oligocene increase in plate convergence rate
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2000)
Magmatically folded and faulted schlieren zones formed by magma avalanching in the Sonora Pass Intrusive Suite, Sierra Nevada, California
(Geological Society of America, 2019-08)
The southwestern margin of the Late Cretaceous Sonora Pass Intrusive Suite, northern Sierra Nevada, California (USA), preserves a densely populated zone of magmatic structures that record dynamic magmatic layer formation ...
Three-dimensional resistivity image of the magmatic system beneath Lastarria volcano and evidence for magmatic intrusion in the back arc (northern Chile)
(Amer Geophysical Union, 2015)
Lazufre volcanic center, located in the central Andes, is recently undergoing an episode of uplift, conforming one of the most extensive deforming volcanic systems worldwide, but its magmatic system and its connection with ...
Schlieren bound magmatic structures record crystal flow sorting in dynamic upper crustal magma mush chambers
(Frontiers Media, 2020-07-24)
The size, longevity, and mobility of upper-crustal magma mushes, and thus their ability to mix and interact with newly arriving magma batches, are key factors determining the evolution of magma reservoirs. Magmatic structures ...
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 ...
Zircon O- and Hf-isotope constraints on the genesis and tectonic significance of Permian magmatism in Patagonia
(Geological Soc Publ House, 2017-09)
The genesis of Permian magmatism in southern South America is actively debated, particularly in relation to the origin of Patagonia. U-Pb zircon ages of c. 255 Ma for igneous rocks from the basement of Tierra del Fuego are ...
A revised interpretation of the Chon Aike magmatic province: Active margin origin and implications for the opening of the Weddell Sea
(2021)
Late Triassic – Jurassic igneous rocks of the Antarctic Peninsula and Patagonia provide evidence for the evolution of the margin of southwestern Gondwana. We present new geochronological (LA-ICP-MS zircon Usingle bondPb ...
