Baffin Island Provides Insights into Origin of Earth's Water (2 of 3)

Caption

Scanning electron microscope images showing one of our Baffin Island rock samples. Large olivine mineral grains dominate this rock (mid-gray colored grains in image A). These olivine grains contain trapped pockets of glass, known as melt inclusions (image B), and this glass contains tiny amounts of water sourced from the mantle plume.
