Evolution of the lower crust in the Ivrea Zone: a model based on isotopic and geochemical data

Abstract

This paper deals with the evolution of the lower crust in the Ivrea Zone and presents a critical review of published and new isotopic data concerning 1) the age and the origin of meta-sedimentary and meta-igneous protoliths, 2) the age and geodynamic significance of granulite facies metamorphism, and 3) the mechanism and timing of uplift of this lower crustal unit. -from Author
