The oldest volcanoes of the Pauzhetka structure may be of Oligocene-Miocene age; during that time the area was in the sea. The sedimentary Paratunka Formation and the Kurilsky complex were deposited during that time; they are exposed east and southwest of Kurile Lake. About of basaltic rocks were erupted during the Miocene-Pliocene. The Pauzhetka depression formed during the Pliocene or Pleistocene and was most likely accompanied by the eruption of the Golygino ignimbrite. The eruption of this ignimbrite occurred 443,000 ± 8000 years ago. Afterwards, a resurgent dome named the Kambalny ridge formed in the Pauzhetka structure, as well as a proto-Ilinsky volcano.
