Hi Folks,
Steve Mojzsis ( stephen.mojzsis@xxxxxxxxxxxx ) and I wish to draw your attention to a session devoted to all aspects of Zircon at the 2015 Goldschmidt Meeting in Prague (http://goldschmidt.info/2015/).
Session
18f: Not Just for Geochronology Anymore: What Zircon Chemistry and
Geochronology can Tell us About Thermal Environments, Fluids and Melts
in Silicate Crusts
Convenors: Steve Mojzsis, Daniel Harlov
Zircon has long been the ‘mineral of choice’ in studies that combine chemical information, gleaned from trace element analyses within different crystal domains, with age(s) of event(s) recorded in those domains. The principal goal of this session is to invite work that explores the most recent advances in zircon geochronology coupled with crystal chemistry and inclusion mineralogy, and how this may be used to date recrystallization, deformation, or partial alteration due to thermal fields, fluids, and/or melts in the crustal environments of Earth, the Moon, Mars, and asteroidal meteorites. Specifically, we invite contributions that explore: (i) how complex internal textures documented in zircon relate to the origins, history, and general chemical nature of the host rock; (ii) how these textures and chemical features can be reproduced experimentally and what this tells us about the thermal environments, fluids, or melts involved; (iii) what the co-existence of mineral inclusions in zircon reveals about the formation and history of the host rock; and (iv) how these data can be modeled. The overall goal of the session is to explore the integration of geochronology, petrology, and geochemistry of terrestrial and extraterrestrial zircon.
