V33C:
Accessorize It: Controls on the Mobility of Trace Elements During Subduction Posters


Submit an Abstract to this Session


Session ID#: 52849

Session Description:
Accessory phases of all types provide key tools for quantifying the trace element geochemistry, stable and radiogenic isotope geochemistry, geochronology, and phase equilibria of rocks in subduction zones. The mobility of traditional accessory phases such as zircon, rutile, titanite, monazite, allanite, and apatite, and perhaps of less studied accessory phases such as sulfides, halides, and oxides, provides a framework for interpreting trace element budgets and elemental fractionation in subduction zones, including volatiles and heat-producing elements. We invite contributions from all aspects of accessory phase geochemistry and petrology related to subduction, from the slab to the arc. We particularly invite studies linking one or more aspects of the subduction factory.
