The Kamchatka Peninsula is one of the most active volcanic arcs and corresponds to subduction of slab near the northwestern edge of the Pacific Plate. The northeastern part of Kamchatka Peninsula involves (i) triple junction including the edge of the Pacific Plate, and (ii) subduction of the seamount chain. As a result, the world-most active volcanic group (Kliuchevskoy Volcanic Group; KVG) with a wide across-arc volcanic zone (400 km) is seen in this area, associated with systematic spatial variations in rock type and chemistry, including adakite near the slab edge. This study aims at understanding the physical-chemical conditions beneath the northeastern Kamchatka Peninsula, by studying monogenetic volcanoes and the primitive lavas near the northeastern end of the volcanic chain.
