Metamorphic minerals: time capsules from a dynamic lithosphere

Metamorphic minerals document the dynamic evolution of our planet, from the Archean to Present and from the grain- to plate-scale. Deciphering these records requires an approach that integrates petrology, geochemistry, chronology, structural analysis and modelling. Our ability to study our dynamic lithosphere through metamorphic geology continues to improve. At the same time, new analyses and approaches reveal issues and pitfalls that inspire future development.

This session aims to highlight integrated metamorphic geology and its use in elucidating the processes that shaped cratons and mountain belts through time. We welcome contributions in petrology, geo- and thermo-chronology, trace-element and isotope geochemistry, thermodynamic modelling, and structural geology—all with a specific focus on studying metamorphosed-metasomatised rocks. Part of the session will be devoted to novel developments and applications in geochronology and micro- to nano-analytical methods.

Invited speakers:
Robert Holder (Johns Hopkins University): "Monazite Eu anomalies revisited: beyond feldspar"
Pierre Lanari (Universität Bern): "An integrated modelling framework for tracing equilibrium relationships in metamorphic rocks"
