Аннотация: Studies of the Klyuchevskaya Group of volcanoes, which have the highest magma production rate across the Kamchatka arc and, in fact, for any arc worldwide, have been published in numerous papers during recent decades. However, modern geochemical studies of Kamen volcano, which is located between Klyuchevskoy, Bezymianny, and Ploskie Sopky volcanoes, have not been carried out and Kamen‘s role in petrogenesis of the Klyuchevskaya Group of volcanoes is unknown. To date only a few papers on this volcano have been published, mostly focusing on a large landslide. Space-time proximity of volcanoes in the Klyuchevskaya Group and a common zone of abnormal seismicity below them suggest their genetic relationship. However, the lavas of neighboring volcanoes are rather different from Kamen lavas: high-Mg and high-Al basalts occur at Klyuchevskoy volcano, Hb-bearing andesites and dacites dominate at Bezymianny, and medium-to-high-K subalkaline rocks at Ploskie Sopky. In this report we present geological, petrographical, mineralogical, and petrochemical data on the rocks of Kamen volcano.
