The Bauru group: a continental Cretaceous unit in Brazil - Concepts based on micropaleontological, oxygen isotope and stratigraphical data
(2001-01-01)
The integration of outcrop and subsurface information, including micropaleontological data, facies and sequence stratigraphic studies, and oxygen isotope analysis, allow us to present a new stratigraphic model for the ...

Jurassic to Early Cretaceous subduction-related magmatism in the Coastal Cordillera of northern Chile (18 degrees 30 '-24 degrees S): geochemistry and petrogenesis
(2007)
Jurassic to Early Cretaceous magmatism in the Coastal Cordillera of northern Chile is represented by thick sequences of mostly basaltic- and esitic to andesitic lava flows and minor sedimentary rocks. The volcanic sucession ...

Geology and U-Pb detrital zircon geochronology coupled with zircon fission tracks of the Jauru formation of Parecis Basin, Brazil
(2021-01-01)
The Jauru Formation fills a symmetric NNW-trending graben whose basement is represented by Calymmian granitic intrusions and the paleoprotorezoic and mesoproterozoic metavolcanic sequence of the Jauru Terrane. The graben ...
Estudio termodinámico de la variabilidad composicional y litológica del magmatismo plutónico de arcos continentales a causa de la cristalización fraccionada
(Universidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2021)
En el modelo actual de magmatismo plutónico, sedimentos del prisma de acreción son subducidos y se mezclan con los basaltos de la corteza oceánica en proporciones variables en el canal de mélange. En cierto punto, estas ...
