Refined exhumation history of the northern Sierras Pampeanas, Argentina [PDF]
Tectonics, 2013 AbstractThe Sierra de Aconquija and Cumbres Calchaquíes in the thick‐skinned northern Sierras Pampeanas, NW Argentina present an ideal setting to investigate the tectonically and erosionally controlled exhumation and uplift history of mountain ranges using thermochronological methods. Although these ranges are located along strike of one another, their

We present new chronological data for the southernmost sector of the Eastern Sierras Pampeanas system of central Argentina. Recent excavations at the Cueva Los Bancos site in Sierra del Morro hill provided a date of ca. 9400 calendar years ago.

This paper focuses on one orogenic belt that formed during the Rinconada phase on the final stage of the Famatinian orogeny, between 445 and 410 Ma, which is well exposed at Sierra de Ramaditas and neighbouring ranges in western Argentina.

Tourmalinites from the Eastern Sierras Pampeanas, Argentina
Ore Geology Reviews, 2004 Abstract In the eastern Sierras Pampeanas, Central Argentina, tourmalinites and coticules are found in close association with stratabound scheelite deposits in metamorphic terranes. In Sierra Grande (Agua de Ramon and Ambul districts) and Sierra de Altautina, tourmalinites are associated with stratabound scheelite deposits related to ...

A-type magmatism in the sierras of Maz and Espinal: A new record of Rodinia break-up in the Western Sierras Pampeanas of Argentina [PDF]
Precambrian Research, 2009 Two orthogneisses have been recognized in the sierras of Espinal and Maz (Western Sierras Pampeanas, NW Argentina) that were emplaced within a Grenvillian metasedimentary sequence. Microcline, plagioclase and quartz are the main rock-forming minerals, with accessory zircon, apatite-(CaF), magnetite, biotite (Fe/(Fe + Mg) = 0.88–0.91 ...

Neotectonic Deformation in the Foreland Basins of the Sierras Pampeanas of Argentina
2023The morphotectonic processes that generated the current landscape occurred by NE-strike transtensive-transpressive tectonic events after the Pleistocene. The progressive deformation of the Sierras Pampeanas towards the east is manifested in the topographic elevations of the Chaco Plain (Dorsal Mujer Muerta and topographic highlands of Otumpa, San ...

Quaternary intraplate deformation in the southeastern Sierras Pampeanas, Argentina
Journal of Seismology, 2001Neogene strain from the subducting Nazca plate is widely distributed in theAndean foreland as a result of flat-lying subduction beneath central westernArgentina (28°–33°S latitude). This fact is indicated byuplifted basement blocks bounded by reverse faults as far as 600 kms eastof the Chilean trench axis.
