Hydrothermal hexahydrite spherules erupted during the 2008-2010 summit eruption of Kīlauea Volcano, Hawai`i'
January 1, 2011
Small (1-3 mm), hollow spherules of hexahydrite have been collected falling out of the magmatic gas plume downwind of Kīlauea’s summit vent. The spherules were observed on eight separate occasions during 2009-2010 when a lake of actively spattering lava was present ~150-200 m below the rim of the vent. The shells of the spherules have a fine bubbly foam structure less than 0.1 mm thick, composed almost entirely of hexahydrite [MgSO4·6H2O] Small microspherules of lava (
