Introduction
Gamchen is a complex volcano composed of four stratovolcanoes, one of which is of Holocene age, atop a shield-like structure. Yuzhny Gamchen and Severny Gamchen are two steep-sided eroded stratovolcanoes of Pleistocene age. Edifice-collapse events at Gamchen during the early Holocene produced several large debris-avalanche deposits below the eastern flanks. Molodoi, a small stratovolcano with a well-preserved, shallow crater, is located on the east flank of Severvy Gamchen. Barany, a young stratovolcano with a youthful crater 500 m wide and 200 m deep, is located on the SE flank of Yuzhny Gamchen volcano. Barany (also spelled Baranii) has been the source of a young lava field that extends to the east and NE and was active between about 3600 and 3000 years ago. Lava domes are found on the flanks of the volcanoes; the youngest of these is Lukovitsa dome, which formed during the final stages of activity at Barany. No historical eruptions are known from the Gamchen complex.---
