Petrological characterization and new ages of estación chuculaqui basalts, Southern Puna, Province of salta
A basaltic and basandesite field is located west of Salar de Arizaro on Caipe range, near the old railroad Chuculaqui Station, in Southern Puna, Salta province. New ages and geochemical data set of these volcanic rocks are presented. Based on their petrographic, geochemical characteristics and field...

Pleistocene Pliocene Puna Volcanism age determination basalt igneous geochemistry lava flow petrography petrology Pleistocene Pliocene volcanism Argentina Puna Salta [Argentina] A basaltic and basandesite field is located west of Salar de Arizaro on Caipe range, near the old railroad Chuculaqui Station, in Southern Puna, Salta province. New ages and geochemical data set of these volcanic rocks are presented. Based on their petrographic, geochemical characteristics and field relationships, two lava flow units have been recognized. The first one, of Pliocene age, is formed by porphyritic basalts with olivine and plagioclase phenocrysts. The second one, of Pleistocene age, is a porphyritic basandesite with plagioclase, pyroxene and amphibole phenocrysts. This information allows the petrologic characterization and new stratigraphic assignation of these rocks, extending the volcanic record of Pliocene age in this region. © 2016, Asociacion Geologica Argentina.
