Zheltovsky volcano


Zheltovsky volcano seen from the rim of the 1901 crater at the eastern slope of Iliinsky volcano. Zheltovsky is a composite edifice. It consists of a large volcano-piedestal crowned with Late Pleistocene caldera, which encloses Late Pleistocene stratovolcano topped with several Holocene extrusive domes. Valley between Zheltovsky and Iliinsky volcanoes is ponded with the Kurile Lake caldera ignimbrite. Inner wall of the 1901 crater at the foreground exposes products of Iliinsky volcano: lava rock is overlain with light pumice known as ZLT or "upper coconuts" with an age of ~4800 14C yr BP and younger tephra layers. Upper stratified package is tephra from the 1901 crater.
