Sandstone Geomorphology: Cerro Colorado, Sierras Pampeanas, Córdoba, Argentina
2021The Cerro Colorado Cultural and Natural Reserve, Cordoba, Argentina, is well known for its impressive rock paintings on sandstone formations. While previous research in the area has focused mainly on archaeological sites, this study describes the surface geology and focuses on the diversity and possible origins of the regional sandstone landforms. This

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.

Proterozoic metavolcanics from western Sierras Pampeanas terrane, Argentina
Journal of South American Earth Sciences, 1994Abstract A series of medium grade metamorphic rocks of the western sector of the Sierras Pampeanas Terrane in central western Argentina are represented by amphibolites, gneisses and schists derived from sedimentary as well as from igneous rocks. The metavolcanics consist of amphibolites, quartz-K-feldspar-muscovite schists, and hornblende-biotite and

The Maz Metasedimentary Series is part of the Maz Complex that crops out in the sierras of Maz and Espinal (Western Sierras Pampeanas) and in the Sierra de Umango (Andean Frontal Cordillera), northwestern Argentina.

Basement orthogneisses, paragneisses, and migmatites in the Sierras de Cordoba of the eastern Sierras Pampeanas of central Argentina represent remnants of a Cambrian arc and accretionary prism that initially formed above a subduction zone along the early Cambrian margin of Gondwana.

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.

On the eastern margin of the Sierra Chica, in a gneissic host rocks metamorphosed under medium to high amphibolite facies (‘Sil-in’ isograd) during the Neoproterozoic–Cambrian M2-D2 event, a body of tonalitic-trondhjemitic composition was discordantly ...
