Extending the Pampean orogen in western Argentina: New evidence of Cambrian magmatism and metamorphism within the Ordovician Famatinian belt revealed by new SHRIMP U–Pb ages
(Pergamon-Elsevier Science Ltd, 2021-02-10)
New SHRIMP U–Pb zircon and monazite ages from the Sierra de Fiambalá (Sierras Pampeanas, NW Argentina) record coeval granitoid peraluminous magmatism and high-grade metamorphism at ca. 525 Ma (Lower Cambrian) that resulted ...
Review of the Cambrian Pampean orogeny of Argentina; a displaced orogen formerly attached to the Saldania Belt of South Africa?
(Elsevier Science, 2018-02)
The Pampean orogeny of northern Argentina resulted from Early Cambrian oblique collision of the Paleoproterozoic-Mesoproterozoic MARA block, formerly attached to Laurentia, with the Gondwanan Kalahari and Rio de la Plata ...
Neoproterozoic evolution of the basement of the South-American platform
(Oxford, 2013)
Neoproterozoic geologic and geotectonic processes were of utmost importance in forming and structuring
the basement framework of the South-American platform. Two large domains with distinct
evolutionary histories are ...
Untangling the Neoproterozoic-Early Paleozoic Tectonic Evolution of the Eastern Sierras Pampeanas Hidden in the Isotopical Record
(Springer, 2018)
The Sierras Pampeanas of Central Argentina are an example of a continuous and fast overlap of episodes of high- to medium- and low-grade metamorphism, deformation, anatexis, magmatism and mineralization along the belts ...
Cordierite-bearing granitic rocks in South America: Contrasting sources and conditions of formation
(Elsevier Ltd, 2019)
Mineralogy, geochemistry and isotopic data for Ediacaran, Ordovician to Devonian, and Upper Triassic cordierite-bearing granitoids respectively from Brazil, Argentina and Chile are discussed here. Syn-collisional Lower to ...
Tectonic and magmatic evolution of the ribeira belt in the highlands of the Rio de Janeiro state, Brazil, from neoproterozoic to lower paleozoicEvolução tectónica e magmática da faixa ribeira entre o neoproterozoico e o paleozoico inferior na região serrana do estado do Rio de Janeiro, Brasil
