Palaeolandsurfaces and neotectonic analysis in the southern Sierras Pampeanas, Argentina
Geological Society, London, Special Publications, 1999Abstract The Sierras Pampeanas of northwestern Argentina are ranges underlain by crystalline basement rocks bounded on their western margins by N-S trending reverse faults along which uplift took place during the Andean orogeny. A pre-uplift regional erosion surface is commonly preserved on the eastern slopes which have been tilted in most ...

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.

Late Holocene faulting in the southeast Sierras Pampeanas of Argentina
Geology, 1996The seismic history of extra-Andean South America is poorly documented. Between lat 26°S and 33°S, about 375 km east of the fold-and-thrust belt that marks the present orogenic front, the block-faulted crystalline basement uplifts of the Sierras Pampeanas in Argentina reveal extensive Quaternary reverse faulting. 14C dates of 1080 ± 70 and 1310 ± 40 yr

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

In the Sierras Pampeanas geomorphic province of central Argentina there are regions where exposed crystalline basement has had no sedimentary cover older than Neogene strata, and other areas where upper Paleozoic and Mesozoic strata overlie the basement.

Granitoids of the Tafi Megafracture (Sierras Pampeanas, Argentina): Petrogenetic implications
Journal of South American Earth Sciences, 1989Abstract A group of small Ordovician-Silurian plutons was emplaced in the Tafi Megafracture of the Sierras Pampeanas, Argentina. These granites, with some peraluminous features, vary from types with andesine, biotite, magmatic epidote, and sometimes sphene, to other muscovitic types with albite and sometimes garnet (almandine-spessartite), reflecting

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 ...
