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 ...
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 ...
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 ...
The basement of the Central Andes: The arequipa and related terranes

New SHRIMP U-Pb data from the Famatina Complex: Constraining Early-Mid Ordovician Famatinian magmatism in the Sierras Pampeanas, Argentina
(Universidad de Barcelona, 2008-12)
New SHRIMP U-Pb zircon ages are reported for igneous and sedimentary rocks of the Famatina Complex, constraining the age of the magmatism and the ensialic basins. Together with whole-rock and isotope geochemistry for the ...
One kilometre-thick ultramylonite, Sierra de Quilmes, Sierras Pampeanas, NW Argentina
(Elsevier, 2015-01)
We describe a 1 km-thick ultramylonite forming the high strain base of the >3.5 km-thick El Pichao shear zone in the Sierra de Quilmes. This shear zone thrusted granulite facies migmatites onto amphibolite facies rocks ...
