Geochemical Characteristics of Melts from the Eastern Volcanic Belt and Sredinny Range of Kamchatka: An Analysis of Evidence from Melt Inclusions
We analyzed published datasets relating to the composition of glasses from melt inclusions in minerals of volcanics from the Eastern Volcanic Belt and Sredinny Range of Kamchatka. A significant difference was found between the distribution of silica concentration in the rocks and melts: intermediate and basic compositions are most common among the rocks, whereas the glasses in melt inclusions are predominantly acidic. The distribution of major and trace elements was analyzed. It was shown that the contents of some elements are environment-specific (e.g., Nb and light REEs). We identified trace element ratios in melts that most strongly correlate with the geodynamic setting.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
