The plates of the outer tectonic shell of our Earth are in ceaseless motion; their collisions create huge earthquakes and their collapse into the Earth introduces surface water to these hot regions at >150km depth, creating melting and volcanic eruption. This project will use iron isotopes to map this surface water as it is introduced to the mantle.

我们地球的外层构造壳的板块在不停地运动；它们的碰撞产生了巨大的地震，它们向地球的崩塌将地表水引入了这些热区，深度达150公里，造成了融化和火山喷发。这个项目将使用铁同位素来绘制地表水进入地幔的地图。
