Gifford Guyot Explained
The Lord Howe Seamount Chain of which Gifford Guyot is an eruptive centre, and part of a pair of coral-capped guyots, formed during the Miocene.[1] [2] The Gifford Marine Park is co-located off the Queensland coast near Brisbane.Lord Howe Seamount Chain with Gifford Guyot in deeper red (clicking on the map enables mouse over)">[{

Geology
The Gifford guyots are two flat‐topped basaltic[3] seamounts, now caped with carbonate sediments with the larger Gifford Guyot dated at 15.6 million years ago[3] but the smaller unnamed seamount of unknown age. They both raise from an abyssal plain 3.4km (02.1miles) below sea level to generally flat summits that are about 250m (820feet) below sea level. This summit plateau is about 55km2 for the unnamed guyot), and 350km2 in area for Gifford Guyot itself.[4]
