Register by 21 May!

The early registration deadline is 21 May and all presenting authors must register for the conference by this date (don't wait until the last moment!). Discounted rates are available for members of the EAG, Geochemical Society and other partner societies. Check your EAG membership, join or renew.

21 May is also the booking deadline for the science workshops, early career workshops, and to apply as mentor or mentee for the mentor program.

An exciting social program

Starting with the icebreaker on Sunday, the Social Program will feature the Early Career Mixer & Boat Tour on Monday, the Conference Banquet on Wednesday, the Goldschmidt Pride & Allies Reception, and the Elements 20th Anniversary Reception on Thursday.

The deadline to register for these events is 9 June but space is limited so book early!
