Abstract
We have identified signs showing mixing of moderately potassic magnesian and high alumina magmas on Klyuchevskoi Volcano based on the analysis of mineral compositions and the geochemistry of trace elements during crystallization. The mineralogy and distribution of Mg, Fe, Cr, Ni, Co, and Al in olivines and clinopyroxenes which are contained in the magnesian basalts and high alumina basaltic andesites discharged by the flank and summit eruptions of Klyuchevskoi in 1938, 1966, 1945, and 1994, all provide evidence of an injection of magnesian basaltic melts into high alumina magma.
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.
