Introduction
The Bolshe-Bannaya ring complex, located north of the Bannaya River WSW of Petropavlovsk-Kamchatskiy, contains a group of Pleistocene andesitic-to-rhyolitic lava domes and late-Pleistocene to Holocene pyroclastic cones (Luchitsky, 1974). It lies within the massive 17 x 32 km wide early Pleistocene Karymshina caldera, which produced about 800 cu km of rhyolitic ignimbrite about 1.78 million years ago. Two areas of late-Pleistocene to Holocene basaltic lava flows are located SE of the ring complex, and another group of younger cones and flows occurs to the NW.---
