Goldschmidt 2013: Final call for sessions, field trips and workshop proposals
GS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The science committee has identified 144 sessions covering many of the exciting areas in Geochemistry. Please take a look at the list of themes and sessions and discuss with your colleagues whether there are any obvious gaps in the program. If there are any obvious gaps in the program, please suggest sessions that you think would help make the program more comprehensive. The additional sessions submitted will be reviewed by the science committee at the end of this month, and included in the list of sessions where appropriate. If you have any questions about suitability or overlap of your proposed session with existing sessions, please contact the appropriate theme leaders. The deadline for this is Oct. 22.

A large number of exciting field trips have been proposed for Goldschmidt2013. If you think you might like to participate in one of these field trips, please click the relevant buttons to register your interest. The deadline for this is Oct. 22.

And finally, it is still possible to propose workshops to take place either before or after Goldschmidt2013. Again, the deadline for this is Oct. 22.
