3-3-3-3-3-3-3-3-3-3-3-3-3 From: John Eichelberger <jceichelberger@xxxxxxxxxx> Dear colleagues, Some of you may find interesting the just-completed special issue Exploring and Modeling the Magma-Hydrothermal Regime: https://www.mdpi.com/journal/geosciences/special_issues/magma_regime Counting the introduction there are 13 papers from authors in 10 countries, covering everything from whiffs of magma in fumaroles through the anatomy of exposed systems to live, unerupted magma itself. And being open access, it's free, of course. The motivation for this was that many papers focus on either magma or hydrothermal domains, yet the two are inextricably linked. More broadly, the 5 editors from 5 countries wish to encourage more interaction among volcanologists, plutonic petrologists, and geothermalists. 3-3-3-3-3-3-3-3-3-3-3-3-3 ------------------------------
