In many cases, careful chemical analysis and petrographic characterization of an accessory mineral can be instrumental in determining the age of a rock, oxygen and sulphur fugacities, or whether metasomatic processes may have occurred, and if so, the approximate composition of the fluids responsible for the metasomatism as well as the P-T conditions under which the metasomatism occurred. In addition, experimental investigations provide important independent constraints on the stability fields of these minerals as well as their relationship to the major rock-forming silicate minerals. The goal of this session is to bring together mineralogists, petrologists, and geochemists to discuss the most recent advances in mineralogical/petrological geochemical and experimental research regarding accessory minerals with respect to what they can tell us about petrogenetic processes in both metamorphic and igneous environments.
