dc.description.abstract |
Klyuchevskoy volcano, located in Kamchatka's subduction zone, is one of the most active arc volcanoes in the world and contains some of the highest 8180 values for olivines and basalts. I present an oxygen isotope and melt inclusion study of olivine phenocrysts in conjunction with major and trace element analyses of 14C and tephrochronologically-dated tephra layers and lavas spanning the eruptive history and the AI-Mg compositional range of the basalt to basaltic andesites found at Klyuchevskoy. A hybrid model of moderately-high 8180 silicate melt from the subducting slab, coupled with high 8180 fluid is provided to best explain Klyuchevskoy's 1) voluminous, high-rate volcanism, 2) unusual high-8180 signature, 3) two endmember basaltic magma, and, 4) hydrous high-AI, high-8180 component. |
