Light micrograph of ash from the Eyjafjallajokull volcano, Island. Volcanic ash consists of pulverised rock (particles with diameter smaller than 2mm up to 1my), minerals and volcanic glass. It is created during explosive eruptions by the shattering of large rocks and the separation of molten rock into tiny pieces. Horizontal object size: 5mm.
