Evidence for multi-stage metasomatism of chlorite-amphibole peridotites (Ulten Zone, Italy): Constraints from trace element compositions of hydrous phases

Marocchi, Marta; Hermann, Joerg; Morten, Lauren

Description

Peridotites from the Ulten Zone (Upper Austroalpine Domain, Central-Eastern Alps, Italy) derive from a mantle wedge environment and record a complex metamorphic history. This study focuses on amphibole-spinel peridotites and chlorite-tremolite peridotites. Chlorite is generally closely intergrown with Cr-spinel, indicating that it grew at the expense of former Al-spinel. No garnet relics or chlorite pseudomorphs after garnet have been found. Moreover, amphibole and chlorite trace element...[Show more]
