The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts through the crust, and how economically important mineral ore deposits form, according to a new article.
