Volcanoes Deliver two different flavors of water

Volcanoes Deliver two different flavors of water | Geochemistry | Scoop.it
Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at areas called subduction zones. By analyzing samples of submarine volcanic glass near one of these areas, scientists found unexpected changes in isotopes of hydrogen and boron from the deep mantle.
