The Derwent Hunter Guyot is an extinct volcanic seamount of the Tasmantid Seamount Chain.
It is a basaltic volcano that erupted between 12,400,000 and 15,400,000 years ago,[2] with survey data that indicates it rises about 4,000 m (13,000 ft) above the local sea floor to a minimum depth of 323 m (1,060 ft).[1] The sediments deposited on top of the alkali olivine basalt[2] originate from the early Middle Miocene.[3] The Derwent Hunter Guyot appears to be double peaked.[4] It was discovered in 1958[1] and described as a seamount in 1961.[5]
The waters above it are incorporated in the Central Eastern Marine Park, an Australian marine park.[6]
