WORKSHOP: APPLYING PHASE EQUILIBRIA MODELLING TO ROCKS, 24-25 AUGUST 2013 |
top |
This workshop on applying phase equilibria modelling to rocks is for metamorphic geologists who already have some experience of using phase equilibria calculation software. The focus will be on methodological aspects, and not on using specific software. The workshop will be held at the University of Florence during 24-25 August 2013 (arrive pm 23 August, depart am 26 August, unless staying for the conference). The number of participants will be limited to ensure adequate time for questions/answers and informal discussions.
The fee per participant is 150 euro, which covers the cost of coffee breaks (x 4), lunches (x 2), and a Tuscan dinner on Saturday 24 August. Registration for the workshop will be via the Goldschmidt2013 web site during the period late February 2013, when online registration opens, and June 25 2013, when early registration finishes. Accommodation costs (bed and breakfast) are to be met by individuals.
During day 1 Professors Roger Powell (University of Melbourne, Australia) and Richard White (University of Mainz, Germany), and possibly others, will address the following topics. Principles and data (thermodynamics of end-members of phases (datasets): methodology and problems; activity-composition relations: methodology and problems; phase diagram principles: grids, compatibility diagrams, and pseudosections). Application to geological problems (thermodynamics and phase diagrams in the context of metamorphic processes: local equilibrium/size of equilibration 'volume', and conjugate variables/choice of phase diagram). Application of phase equilibria to rocks (interpretation of petrographic features; constraining P–T conditions/paths, for calculating fluid/melt production/loss, interpretation of reaction textures; relating field information, petrography and mineral chemistry to phase diagrams; the importance of separating the model from nature).
Day 2 will comprise short oral presentations and posters that showcase studies addressing particular problems. Registrants who are interested in contributing to Day 2 should send a title and short abstract to the Co-conveners before 25 June 2013 (the registration deadline); please state whether you are requesting an oral presentation or a poster. We hope to make space available for posters to be on display throughout both days of the workshop. The final program for Day 2 will be posted here by mid July.
The workshop will finish in time for participants who are staying for the Goldschmidt conference to attend the icebreaker.
