Nautiloid cephalopod concentration beds of the San Juan Formation (Middle Darriwilian) of the Argentine Precordillera
(Asociación Paleontológica Argentina, 2013-07)
Concentrations of orthoconic nautiloid cephalopods on bedding planes of the San Juan Formation limestones are for first time associated to the Yangtzeplacognathus crassus Zone (Middle Ordovician). Nautiloid cephalopod ...
Bivalves and brachiopods in the Carboniferous - Early Permian of Argentine Precordillera: Diversification and faunal turnover in Southwestern Gondwana
(Universidad de Barcelona, 2010-12)
Diversification patterns and faunistic turnovers of bivalves and brachiopods through the Carboniferous - Early Permian interval in the central western Argentinian basins are analyzed and compared with the global events ...
The geometry of the active strike-slip El Tigre Fault, Precordillera of San Juan, Central–Western Argentina: integrating resistivity surveys with structural and geomorphological data
(Springer, 2013-03)
The geometry and related geomorphological features of the right-lateral strike-slip El Tigre Fault, one of the main morphostructural discontinuities in the Central– Western Precordillera of Argentina, were investigated. ...
Sr–Nd isotope data of basement rocks from the northernmost argentine Precordillera and its implications for the early Paleozoic evolution of SW Gondwana margin
(Pergamon-Elsevier Science Ltd., 2014-08)
The Precordillera terrane (Cuyania) in western Argentina is commonly accepted as an exotic fragmentderived from Laurentia in the Early Paleozoic. Evidence supporting such an interpretation is manly basedon similarities in ...
A lowermost Ordovician tabulate-like coralomorph from the Precordillera of western Argentina: a main component of a reef-framework consortium
(Paleontological Society, 2016-12)
Although putative corals of uncertain affinities occur in the early Cambrian, the earliest definite tabulatecorals have not been described prior to the Early Ordovician in North America. This paper reports a new findingof ...
The E-MORB like geochemical features of the Early Paleozoic mafic-ultramafic belt of the Cuyania terrane, western Argentina
(Elsevier, 2013-08)
The Argentine Precordillera is located in the central western region of Argentina, within the Central Andes. Throughout its westernmost sector, mafic and ultramafic bodies including serpentinites, mafic granulites, ...
Post-glacial Hirnantian (upper Ordovician) bryozoans from western Argentina: implications for survival and extinction patterns
(Asociacion Paleontologica Argentina, 2014-06)
Two bryozoan taxa occurring in the Hirnatian (Upper Ordovician) deposits in western Argentina document a first postglacial community associated with a mid-to high-latitude brachiopod assemblage, known as the typical Hirnantia ...
Silurian-Devonian coral associations across a sequence stratigraphic boundary in the Argentine Precordillera
(John Wiley & Sons Ltd, 2013-03)
Silurian and Devonian corals occur abundantly in siliciclastic rocks of the Argentine Precordillera. They are distributed along a Silurian stormdominated shallow-water platform, a transitional restricted nearshore environment, ...
Age Constraints on the Portezuelo Del Tontal Formation (Middle–Upper Ordovician) of the Western Argentine Precordillera: First Insights from Conodont BiostratigraphyPrecisiones sobre la edad de la Formación Portezuelo del Tontal (Ordovícico Medio-Superior) de la precordillera occidental argentina: primera aproximación con bioestratigrafía de conodontes
(Asociación Paleontológica Argentina, 2020-09)
Se analiza la primera fauna de conodontes recuperada de la Formación Portezuelo del Tontal (FPT) en la Sierra del Tontal, Provincia de San Juan, brindando un preciso control bioestratigráfico para las potentes secuencias ...
Sedimentology and sequence stratigraphy from a mixed (carbonate-siliciclastic) rift to passive margin transition: The early to middle cambrian of the argentine precordillera
(Elsevier Science, 2015-03)
Through the analysis of facies stacking patterns, geometries and bounding surfaces, sequence stratigraphy provides a framework to understand sedimentary facies distribution and evolution. Many published works contain ...
