All share research either in active volcanic terrains or through their dealings with the chemistry of hyper-acid fluids in the environment. Exchange of data, methods and factual knowledge between those different constituencies will be fruitful for future research. Funding will provide support to graduate students from universities in the USA to attend this meeting.
