Protracted late magmatic stage of the Caleu Pluton: Insights from zircon data and thermal modeling.

Abstract

Zircon U-Pb geochronology and geochemistry are combined with whole-rock composition and thermal modeling to decipher the late magmatic stage of the composite Cretaceous Caleu pluton, which consists of four lithological zones: Gabbro-Diorite Zone (GDZ), Qu
