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 ...
Conflicting structural and geochronological data from the Ibituruna quartz-syenite (SE Brazil): Effect of protracted ""hot"" orogeny and slow cooling rate?
(ELSEVIER SCIENCE BV, 2009)
The Ibituruna quartz-syenite was emplaced as a sill in the Ribeira-Aracuai Neoproterozoic belt (Southeastern Brazil) during the last stages of the Gondwana supercontinent amalgamation. We have measured the Anisotropy of ...
