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)
From Crustal Thickening to Orogen‐Parallel Escape: The 120‐Myr‐Long HT‐LP Evolution Recorded by Titanite in the Paleozoic Famatinian Backarc, NW Argentina
(American Geophysical Union, 2020-09)
Exposed sections of accretionary orogens allow reconstruction of their tectonic evolution. Most commonly, orogens are characterized by two‐dimensional shortening perpendicular to the orogenic front. We describe the midcrustal ...
Tectono-metamorphic evolution of a convergent back-arc: The Famatinian orogen, Sierra de Quilmes, Sierras Pampeanas, NW Argentina
(Geological Society of America, 2017-06)
Back-arcs are hot regions of enduring weakness in the hinterland of subduction zones that are commonly sites of strain localization, forming mobile belts that, in some cases, develop into mountain belts. Their evolution ...
Review of the geodynamic evolution of the SW margin of Gondwana preserved in the Central Andes of Argentina and Chile (28°-38° S latitude)
(Pergamon-Elsevier Science Ltd, 2017-11)
In the southwestern margin of Gondwana, preserved in the Argentinean-Chilean Andes (28-38° S latitude), three subduction events, Famatinian, Chanic and Gondwanan, took place from the Ordovician to the middle Permian. The ...
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 ...
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 ...
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 ...
The Pre-Andean phases of construction of the Southern Andes basement in Neoproterozoic-Paleozoic times
(Springer, 2017)
During the late Neoproterozoic and Paleozoic times, the Southern Andes of Argentina and Chile (21º-55º S) formed part of the southwestern margin of Gondwana. During this period of time, a set of continental fragments of ...
