Article
The Precuyano cycle in northern Cordillera del Viento corresponds to a volcano-sedimentary sequence with U-Pb zircon SHRIMP ages between 187. 9 ± 1.8 and 181.2 ± 2.4 Ma (Pliensbachian to lower Toarcian). The lower section is predominantly basic to mesosilicic with few clastic and a distinctive jasper level. The upper section is volcanic, essentiall...

Mineralog y and genetic aspects of the "La Casualidad" seafloor volcanogenic Mn deposit, cerro Atravesada, Neuquén. La Casualidad ore deposit is characterized by manganiferous layers interbedded with limestones and tuffs of the Chachil formation (Pliensbachian). The identified mineralogy comprises carbonates (rhodochrosite, calcite), sulfates (bari...

The studied Carboniferous units comprise metasedimentary (Guaraco Norte Formation), pyroclastic (Arroyo del Torreón Formation), and sedimentary (Huaraco Formation) rocks that crop out in the northwestern Neuquén province, Argentina. They form part of the basement of the Neuquén Basin and are mostly coeval with the Late Paleozoic accretionary prism...

La identificación y estudio de una mineralización tipo Banded Iron Formation (BIF) en el sector septentrional de la Cordillera del Viento, al norte de los 37° latitud sur y entre 70°30' y 70°40' de longitud oeste permitió definir y mapear la Formación Colomichicó (Zappettini y Dalponte, 2009) con la cual se vincula genéticamente. Originalmente, la...

The Los Menucos ichnofauna from the Río Negro province in Argentina, is at present a unique Triassic track association known from Patagonia. The new footprints described in the present study were collected from the same levels where the original tetrapod ichnites from Casamiquela's works were exhumed. The track-bearing levels are included in the Lo...
