The Taupo Bank (also previously known as Mont Taupo,Taupo Guyot or Taupo Tablemount) is an extinct volcanic seamount of the Tasmantid Seamount Chain.
Topographic map of Zealandia that includes the Taupo Bank at the sea bottom of the Tasman Sea in the line of the Tasmantid hotspot seamounts off the east coast of Australia.
It is a basaltic volcano that erupted between 10,300,000 to 11,400,000 years ago,[1] with survey data that indicates it rises about 3,160 m (10,370 ft) above the local sea floor to a minimum depth of 128 m (420 ft).[2] The sediments deposited on top of the alkali olivine basalt[1] originate from the Late Miocene.[3] It was likely a coral-capped volcanic seamount during the Pleistocene low sea level.[4] It was described as a seamount in 1961.[5]
The waters above it are incorporated in the Central Eastern Marine Park, an Australian marine park.[6]
