(Elsevier Science, 2012-06)
The Sierras Pampeanas orogen, in northwestern Argentina, hosts significant Sn-W mineralization in a variety of mostly epizonal granite stocks emplaced in variably metamorphosed country rocks. The San Blas, Huaco and El ...
U–Pb SHRIMP detrital zircon ages from the Neoproterozoic Difunta Correa Metasedimentary Sequence (Western Sierras Pampeanas, Argentina): Provenance and paleogeographic implications
(Elsevier Science, 2015-11)
The central and eastern parts of the Sierra de Pie de Palo (Western Sierras Pampeanas, Argentina) areformed by a Mesoproterozoic basement and a Neoproterozoic sedimentary cover. Both were involvedin an accretionary orogeny ...
The metamorphic basement of the southern Sierra de Aconquija, Eastern Sierras Pampeanas: Provenance and tectonic setting of a Neoproterozoic back-arc basin
(Pergamon-Elsevier Science Ltd, 2018-02)
The Eastern Sierras Pampeanas are mainly composed of Neoproterozoic–early Palaeozoic metamorphic complexes whose protoliths were sedimentary sequences deposited along the western margin of Gondwana. South of the Sierra de ...

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 ...
A-type magmatism in the sierras of Maz and Espinal: A new record of Rodinia break-up in the Western Sierras Pampeanas of Argentina
(Elsevier Science, 2009-08)
Two orthogneisses have been recognized in the sierras of Espinal and Maz (Western Sierras Pampeanas, NW Argentina) that were emplaced within a Grenvillian metasedimentary sequence. Microcline, plagioclase and quartz are ...
