Orthogneisses of tonalitic to granodioritic composition with calc-alkaline, metaluminous to peraluminous characteristics crop out at the region of Pontalina. The orthogneisses exhibit negative anomalies of Nb, Ta, P and ...
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 ...
