Mount Gambier (volcano)
From Wikipedia, the free encyclopedia
Mount Gambier is a maar complex in South Australia associated with the Newer Volcanics Province. It contains four lake-filled maars called Blue Lake, Valley Lake, Leg of Mutton Lake, and Browne's Lake.[1] It is one of Australia's youngest volcanoes which formed about 4,900 years ago.
Mount Gambier is thought to have formed by a mantle plume center called the East Australia hotspot which may currently lie offshore.[1]
