La Formación Puncoviscana (Neoproterozoico-Cámbrico inferior), aflorante en Río León, provincia de Jujuy, fue reconocida en cuatro perfiles sedimentológicos con litofacies de conglomerados calcáreos, cuarcitas, meta-areniscas ...
Basin evolution of Gondwan at the Neoproterozoic Cambrian transition
(E Schweizerbartsche Verlags, 2012-01)
The Puncoviscana Formation is an important stratigraphic sequence of sandstones and shales, with intercalated conglomerates, limestones and volcanic rocks. It was deposited at the Neoproterozoic-Cambrian boundary in a ...

Las ritmitas mareales constituyen una clara evidencia de sedimentación afectada por las mareas pudiendo preservar los períodos mareales inducidos astronómicamente al momento del depósito. Las investigaciones de secuencias ...
The Puncoviscana Formation of northwest Argentina: U-Pb geochronology of detrital zircons and Rb-Sr metamorphic ages and their bearing on its stratigraphic age, sediment provenance and tectonic setting
(E Schweizerbartsche Verlags, 2008-06)
U-Pb ages of detrital zircons from greywacke, and Rb-Sr metamorphic ages of slate from the Puncoviscana Formation of northwest Argentina are reported, and used to constrain the depositional age, metamorphic history, and ...
Geothermobarometry of very low-grade metamorphic pelites of the Vendian–Early Cambrian Puncoviscana Formation (NW Argentina)
(E Schweizerbartsche Verlags, 2013-06)
The Vendian–Early Cambrian Puncoviscana Formation is a pelite-greywacke turbidite sequence affected by polyphase deformation cropping out extensively in the Cordillera Oriental of northwestern Argentina. Previous X-ray ...

Basic to ultrabasic (melanocrat basalts, ankaramites, alkali basalts, mugearites) and mesosilicic(latites) volcanic rocks rhythmically intercalated with me tavackes and metapelites of Puncoviscana Formation are reported. ...
Early Paleozoic accretionary orogenies in NW Argentina: Growth of West Gondwana
(Elsevier Science, 2018-12)
Two Early Paleozoic orogenic cycles in the Gondwana margin of NW Argentina were driven by subduction, and interrupted by collision of continental ribbons of Laurentian affinity. Subduction started at the passive margin of ...
