Lower–Middle Ordovician brachiopods from the Eastern Cordillera of Peru: biostratigraphical and palaeobiogeographical significance
(Estonian Academy PublishersPE, 2023-06)
Lower–Middle Ordovician brachiopods are well known from the Central Andean Basin of Argentina and Bolivia, but relatively little data comes from its northern prolongation in the Altiplano and the Eastern Cordillera of Peru. ...
Petrology and provenance of the Toro Negro Formation (Neogene) of the Vinchina broken-foreland basin (Central Andes of Argentina)
(Elsevier, 2014-01)
Detrital modes of sandstones and conglomerates of the Toro Negro Formation (Late Miocene-early Pliocene) were used to analyze the evolution of the broken-foreland stage of the Vinchina Basin (28°30′–29°00′ S and 68°30′–68°20′ ...
Bentonite geochronology, marine geochemistry, and the Great Ordovician Biodiversification Event (GOBE)
(Elsevier Science, 2012-03)
Attribution of Ordovician climate forcing to explosive volcanism and the potential global importance of volcanism in Ordovician biodiversification suggest the necessity of evaluating the relationships between K-bentonite ...
Phylogeography and genetic structure in the Cnemidophorus longicauda complex (Squamata, Teiidae)
(Herpetologists League, 2006-12)
Cnemidophorus longicauda is a poorly-studied species of whiptail lizard distributed in theMonte Desert region of Argentina. Some variation in dorsal color pattern has been observed between northern and southern populations ...
Reinterpretation of the Ordovician rotations in NW Argentina and Northern Chile: A consequence of the Precordillera collision?
(Springer, 2011-04)
Early Paleozoic paleomagnetic data from NW Argentina and Northern Chile have shown large systematic rotations within two domains: one composed of the Western Puna that yields very large (up to 80°) counter-clockwise ...
Stable isotope composition of middle Miocene carbonates of the Frontal Cordillera and Sierras Pampeanas: Did the Paranaense seaway flood western and central Argentina?
(Elsevier Science, 2011-08)
The geographic extent, interconnectedness and chronology of the Miocene "Paranaense" epeiric seaway have been the subject of considerable debate. Understanding the timing and location of this marine incursion is significant ...

(Asociación Geológica Argentina, 2020-01)
Se presenta un análisis integrado de la magnetoestratigrafía reinterpretada, a partir de los datos de Ré (2008), en función de nuevas edades U-Pb obtenidas por Amidon et al. (2016), con modelos de estratigrafía secuencial ...
Syndesmorion stellatum (Fijałkowska) Foster et Afonin chlorophycean algae and associated microphytoplankton from lacustrine successions of the La Veteada Formation (late Permian), Paganzo Basin, Argentina. Paleoenvironmental interpretations and stratigraphic implications
(Elsevier Science, 2017-03)
A diverse microphytoplankton assemblage recovered from terrestrial deposits of the La Veteada Formation, north of the La Rioja Province, Paganzo Basin, Argentina, is described and illustrated. The ~ 180 m thick sedimentary ...
