Call for session suggestions: The Goldschmidt conference is the most important forum for the discussion of recent results in geochemistry and related fields. The theme leaders have now identified 23 themes and the whole geochemistry community is invited to make suggestions for sessions. Now is your chance to make sure that your area of science is represented at the conference. If you have any questions about the science, or if you want advice about your suggestion, please ask the theme leader (whose details are available on the conference website in their theme). The call for sessions is open now until November 1, 2016. Call forworkshop proposals: The Goldschmidt2017 conference in Paris will carry on the tradition of running high quality teaching workshops and seminars on the weekend before the conference. Every year, the Goldschmidt conference draws in thousands of delegates from geochemistry and related subjects: the perfect audience for a workshop that teaches the skills, or discusses the topics, of our community. Is there a workshop or Town Hall meeting that you want to lead? If so, please submit your proposal for review before November 1, 2016.
