Melt inclusions

Caption

To reconstruct the past, ASU scientists have taken advantage of extensive microanalyses from the tiniest blobs and bubbles that are the best representation of the composition of magma from Sunset Crater before the eruption, known as melt inclusions. How tiny? Melt inclusions are less than a thousandth of an inch across. They become embedded in time within growing crystals of the magma plumbing system that forms before a volcano erupts.
