Protracted fluid-induced melting during Barrovian metamorphism in the Central Alps

Rubatto, Daniela; Hermann, Joerg; Berger, Alfons; Engi, Martin

Description

The timing and dynamics of fluid-induced melting in the typical Barrovian sequence of the Central Alps has been investigated using zircon chronology and trace element composition. Multiple zircon domains in leucosomes and country rocks yield U-Pb ages spanning from ∼32 to 22 Ma. The zircon formed during Alpine melting can be distinguished from the inherited and detrital cores on the basis of their age, Th/U (<0.1) and trace element composition. Ti-in-zircon thermometry indicates crystallization...[Show more]
