  2. Assessing the link between mantle source and sub-volcanic plumbing in the petrology of basalts from the 2001 and 2002/2003 eruptions of Mount Etna, Sicily: Evidence from geochemical and helium isotope data

    31 Dec 2010 | Publications | Contributor(s): Ian M. Coulson

    The 2001 and 2002-2003 flank eruptions of Mt. Etna consisted of near continuous explosive activity and sporadic lava flows. Previous studies have suggested that distinct magmas were simultaneously tapped by fissures in different parts of the volcano, indicating a complex plumbing system. From...
