Postdoctoral Fellowship: EAR-PF: The origins and role of hydrogen in ocean island lavas.

Overview

Although abundant in the form of water near Earth’s surface, hydrogen is only a minor component of Earth’s crust and mantle. When tectonic plates collide, sinking (i.e., subducting) plates transport hydrogen to the deep mantle. Much later, subducted hydrogen may return to Earth’s surface through volcanic…
