Activities Presentations


Commission members are encouraged to send by E-mail a copy of their original PowerPoint presentation or poster to Ariadne Argyraki. If the file is very large, do please send it via a file transfer application to 


The objective is to assist all Commission members to make good presentations in order to promote effectively the philosophy behind the Global Geochemical Baselines project. This objective can be realised by having as much data and information as possible from the national and international efforts.


Do please note to write on the last slide the conference/symposium where the presentation was first made. PowerPoint presentations are available for downloading in *.pdf format in the different sections of the Website.  The original presentations and posters, due to their size, may be obtained from the Public Relations Chair, Ariadne Argyraki [E-mail:].
