The Eyjafjallajokull volcano began erupting in March ... Most of it was very fine particles which formed an ash cloud, rising 6-10km (20,000-35,000 feet) into the atmosphere. Ash clouds pose great ...

Through geochemical analyses, geoscientists at Heidelberg University have shown that the millimeter-sized sapphire grains found in the Eifel (Germany) formed in association with volcanism.
