Depositional age and provenance in the San Luis Formation, Sierras Pampeanas, Argentina: Evidence from detrital zircon studies
(Pergamon-Elsevier Science Ltd, 2019-10)
The San Luis Formation is one of the lithostratigraphic units constituting the early Paleozoic crystalline basement of the Sierras de San Luis, which are part of the Sierras Pampeanas of central Argentina. The low-grade ...
The Neoproterozoic-early Paleozoic metamorphic and magmatic evolution of the Eastern Sierras Pampeanas: an overview
(Springer, 2010-12)
The Eastern Sierras Pampeanas were structured by three main events: the Ediacaran to early Cambrian (580–510 Ma) Pampean, the late Cambrian–Ordovician (500–440 Ma) Famatinian and the Devonian-Carboniferous (400–350 Ma) ...
Early Cambrian multiple-sourced plutonism in the Eastern Sierras Pampeanas, Córdoba, Argentina: Implications for the evolution of the early Paleozoic Gondwana margin
(Pergamon-Elsevier Science Ltd, 2021-03)
Four major igneous suites with different geochemical characteristics are identified in the accretionary complex of the Pampean orogeny from the southern Sierras de Córdoba, Argentina. Crystallization ages of gabbroic and ...
P-T-t path reconstruction in a syn-deformational migmatization event along the north-central portion of Sierra de Comechingones, Córdoba, Argentina
(Pergamon-Elsevier Science Ltd, 2021-12)
The granulite-complexes of the Sierras de Córdoba, inside context of Sierras Pampeanas, expose the deeply-uplifted internal metamorphic zone of an early Cambrian orogen. One of the largest granulite-complexes in 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 ...
Tectonic significance and consequences of the Gondwanide orogeny in northern Patagonia, Argentina
(Elsevier Science, 2008-10)
The tectonic configuration of northern Patagonia is recognized through geological and geophysical studies, which define several areas characterized by positive and negative gravity anomalies with steep gravity gradients. ...
The juxtaposition of Cambrian and early Ordovician magmatism in the Tafí del Valle area: Characteristics and recognition of Pampean and Famatinian magmatic suites in the easternmost Sierras Pampeanas
(Pergamon-Elsevier Science Ltd, 2020-12)
Along more than 1000 km, the boundary between the Pampean and Famatinian belts separates the Cambrian magmatism to the east (540-515 Ma) from the easternmost granitic rocks ascribed to the Famatinian orogeny to the west ...
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 ...
LA-ICP-MS U–Pb columbite ages and trace-element signature from rare-element granitic pegmatites of the Pampean Pegmatite Province, Argentina
(Elsevier Science, 2021-04)
Crystals of the columbite-group minerals (CGM) from 23 rare-element granitic pegmatites of the Pampean Pegmatite Province (PPP) were analyzed by LA-ICP-MS technique. The resulting database shows weighted mean 206Pb/238U ...
