Famatinian orogen on the South American plate: An introduction
(Pergamon-Elsevier Science Ltd, 2021-01)
This Special Issue gathers together a series of contributions related to
the Famatinian orogen in the South American plate. This orogen was
initially defined in northwestern Argentina by Aceñolaza and Toselli
(1976) and ...
Low-pressure emplacement of epidote-bearing metaluminous granitoids in the Sierra de Chepes (Famatinian Orogen, Argentina) and relationships with the magma source
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2001)
Reconstruction of the Early Ordovician Famatinian arc through thermobarometry in lower and middle crustal exposures, Sierra de Valle Fértil, Argentina
(Elsevier Science, 2013-01)
The crustal structure of the Famatinian paleoarc is reconstructed by determining the metamorphic crystallization P–T conditions from metasedimentary rocks at various structural levels in the Valle Fértil section. The bulk ...
The geodynamic history of the Famatinian arc, Argentina: A record of exposed geology over the type section (latitudes 27°- 33° south)
(Pergamon-Elsevier Science Ltd, 2020-06-14)
The Famatinian arc, over central-western Argentina, is one of the few examples of exposed crustal arc cross-section in the world. This Paleozoic magmatic arc and orogenic system on the Earth's surface offers unique insights ...
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 ...
Upper-crustal architecture and record of Famatinian arc activity in the Sierra de Narváez and Sierra de Las Planchadas, NW Argentina
(Pergamon-Elsevier Science Ltd, 2021-01)
The 495 to 450 Ma Famatinian orogen, exposed throughout central and northwestern Argentina, formed from east-directed subduction under the Gondwanan margin. The Sierra de Narváez and Sierra de Las Planchadas preserve a ...
Tectonothermal evolution and exhumation history of the Paleozoic Proto-Andean Gondwana margin crust: The Famatinian Belt in NW Argentina
(ELSEVIER SCIENCE BV, 2011)
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. Thermobarometric and geochronological ...
High T/P evolution and metamorphic ages of the migmatitic basement of northern Sierras Pampeanas, Argentina: Characterization of a mid-crustal segment of the Famatinian belt
(Pergamon-Elsevier Science Ltd, 2011-03)
New petrologic, thermobarometric and U-Pb monazite geochronologic information allowed to resolve the metamorphic evolution of a high temperature mid-crustal segment of an ancient subduction-related orogen. The El Portezuelo ...
Las Matras Block, Central Argentina (37°S-67°w): The southernmost Cuyania terrane and its relationship with the Famatinian orogeny
(Elsevier Science, 2004-12)
The Las Matras Block in Central Argentina constitutes the southernmost part of the Cuyania terrane, which was accreted to the southwestern margin of Gondwana during the Early to Mid Ordovician Famatinian orogeny. The ...
High T/P evolution and metamorphic ages of the migmatitic basement of northern Sierras Pampeanas, Argentina: Characterization of a mid-crustal segment of the Famatinian belt
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
New petrologic, thermobarometric and U-Pb monazite geochronologic information allowed to resolve the metamorphic evolution of a high temperature mid-crustal segment of an ancient subduction-related orogen. The EI Portezuelo ...
