Aeromagnetic Surveys as a Tool for Regional Geological Mapping: A Review of the Case Study of the Southeastern Pampean Ranges, Argentina
(ARC Publications, 2021-03)
A geological interpretation of the aeromagnetic survey of the southeastern Pampean Ranges of Argentina –referred to as “Sierras Pampeanas Orientales” in Spanish– , whose basement ages range from late Neoproterozoic to early ...
Metamorphic fingerprints of Fe-rich chromitites from the Eastern Pampean Ranges, ArgentinaEvidencias del metamorfismo en cromititas ricas en Fe del oriente de las Sierras Pampeanas, Argentina
(Universidad Nacional Autónoma de México, 2020-04)
Las cromititas incluidas en los cuerpos de harzburgita serpentinizada de Los Congos y Los Guanacos (Sierras Pampeanas Orientales, norte de Argentina) registran una evolución metamórfica compleja. La hidratación de las ...
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) ...
Geochronology of igneous rocks in the Sierra Norte de Córdoba (Argentina): Implications for the Pampean evolution at the western Gondwana margin
(Geological Society of America, 2014-05)
U-Pb zircon data (secondary ion mass spectrometry [SIMS] and thermal ionization mass spectrometry [TIMS] analyses) from igneous rocks with differing structural fabrics in the Sierra Norte de Córdoba, western Argentina, ...
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 ...
Metamorphic and tectonic evolution at 31°36′S across a deep crustal zone from the Sierra Chica of Córdoba, Sierras Pampeanas, Argentina
(Pergamon-Elsevier Science Ltd, 2010-11)
A geological section at 31°36′S cut the main structures of a representative area of the deep crust in the Sierra Chica (Sierras Pampeanas of Córdoba, Argentina), where associations of high-grade gneisses, migmatites, ...
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 present investigation was developed in the area of Sierra de Pie de Palo, located at approximately 31º 30’ S and 68°00’ W, in the central eastern portion of San Juan province, Argentina. The main objective is to analyze ...
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 ...
