  Information - GMPV11 The multi-functional roles of accessory minerals in metamorphic and igneous processes

Event Information
Accessory minerals can be used for a variety of purposes in metamorphic and igneous rocks such as measuring general chemical states in the rock (e.g. fO2) or determining the composition and role of fluids during metasomatic alteration or partial melting. In addition, accessory minerals such as zircon, apatite, monazite, xenotime, allanite, and titanite can be used to date a series of chemical events in the rock starting, if possible, with the origin of the mineral itself during the initial crystallization or metamorphic event.
The goal of this session will be to explore the most recent advances in how accessory minerals may be utilized to evaluate mineral stability and equilibria in a rock, the history of chemical or metasomatic events in the rock, as well as the complexities and pitfalls of using these minerals to date such events.
