Magma evolution and open-system processes at Shiveluch Volcano: Insights from phenocryst zoning

Phenocryst zoning patterns are used to identify open-system magmatic processes in the products of the 2001 eruption of Shiveluch Volcano, Kamchatka. The lavas and pumices studied are hornblende-plagioclase andesites with average pre-eruptive temperatures of ∼840°C and fO2 of 1.5-2.1 log units above...
