Guyot, isolated submarine volcanic mountain with a flat summit more than 200 metres (660 feet) below sea level. Such flat tops may have diameters greater than 10 km (6 miles). (The term derives from the Swiss American geologist Arnold Henry Guyot.) In the Pacific Ocean, where guyots are most.
In marine geology, a guyot (/ ˈ ɡ iː. oʊ, ɡ iː ˈ oʊ /), [1] [2] also called a tablemount, is an isolated underwater volcanic mountain with a flat top more than 200 m (660 ft) below the surface of the sea. [3]
A flat-topped, extinct submarine volcano having an elevation of over 1,000 m (3,280 ft) above the ocean floor. Guyots are thought to form as volcanos in sea-floor spreading zones and to become extinct as they move away from the spreading zones through plate tectonic forces.
In marine geology, a guyot (/ ˈɡiː.oʊ, ɡiːˈoʊ /), [1][2] also called a tablemount, is an isolated underwater volcanic mountain (seamount) with a flat top more than 200m (660ft) below the surface of the sea. [3] The diameters of these flat summits can exceed 10km (6mi). [3]
A guyot is a flat-topped submarine mountain, or seamount, that once emerged above sea level as a volcanic island, and then resubmerged when volcanic activity ceased. Erosion by wave activity during submergence creates the characteristic flat-topped profile of a guyot.
Guyots provide valuable information about the geological history of ocean basins and can indicate past volcanic activity and sea-level changes. Unlike seamounts, guyots have been completely submerged and eroded, which makes them distinct in terms of their shape and formation process.
Fewer examples. Guyots are most commonly found in the Pacific Ocean. While serving with the U.S. Navy in the Pacific during World War II, he was the first to report the existence of the truncated seamounts known as guyots. The Great Meteor Tablemount is a guyot standing at over 4,000 meters.
