Oxygen is the most abundant element in the Earth's crust, mantle, and fluids and therefore its
isotopic composition provides robust constraints on magma genesis. Application of oxygen …

The primary goal of this paper is to summarize all of the published data on the Tolbachik
volcanic massif in order to provide a clear framework for the geochronologic, petrologic …

High-precision electron microprobe analyses were obtained on olivine grains from
Klyuchevskoy, Shiveluch and Gorely volcanoes in the Kamchatka Arc; Irazú, Platanar and …

Equilibrium crystallization experiments have been performed on a primitive high-MgO basalt
(HMB) from Soufrière, St. Vincent, with three initial H2O contents (0· 6, 2· 3 and 4· 5 wt%), at …

We present a broad overview of the 2012–13 flank fissure eruption of Plosky Tolbachik
Volcano in the central Kamchatka Peninsula. The eruption lasted more than nine months …

Discovery of seafloor volcanism west of Buldir Volcano, the westernmost emergent volcano
in the Aleutian arc, demonstrates that surface expression of active Aleutian volcanism falls …

Reliable evaluation of CO 2 contents in parental arc magmas, which can be preserved in
melt inclusions in phenocrysts, is required to verify the proposed efficiency of CO 2 recycling …

We present new major and trace element, high-precision Sr–Nd–Pb (double spike), and O-
isotope data for the whole range of rocks from the Holocene Tolbachik volcanic field in the …

Klyuchevskoy volcano, in Kamchatka's subduction zone, is one of the most active arc
volcanoes in the world and contains some of the highest δ 18 O values for olivines and …

Siliceous slab-derived partial melts infiltrate the sub-arc mantle and cause rock-melt
reactions, which govern the formation of diverse primary arc magmas and lithological …
