  2. Guyot - Wikipedia

    en.wikipedia.org/wiki/Guyot

    The Bear Seamount (left), a guyot in the northern Atlantic Ocean. 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] The diameters of these flat summits can exceed 10 km (6 mi). [3]

  3. Koko Guyot - Wikipedia

    en.wikipedia.org/wiki/Koko_Guyot

    Koko Guyot is a 48.1-million-year-old guyot, [3] a type of underwater volcano with a flat top, which lies near the southern end of the Emperor seamounts, about 200 km (124 mi) north of the "bend" in the volcanic Hawaiian-Emperor seamount chain. [5]

  4. Bear Seamount - Wikipedia

    en.wikipedia.org/wiki/Bear_Seamount

    The Bear Seamount is the first guyot in a chain of about 30 extinct volcanoes extending in a straight line south-eastwards from the edge of the continental shelf near Woods Hole, Massachusetts to north-east of Bermuda. These seamounts resulted from the movement of a mantle plume hotspot. This hotspot is now under the Great Meteor Seamount.

    As the volcano sinks and erodes, it first becomes an atoll island and then an atoll. Further subsidence causes the volcano to sink below the sea surface, becoming a seamount. Once a seamount is 600 m (2,000 ft) or more under the surface, it is also classed as a guyot.

  6. Nintoku Seamount - Wikipedia

    en.wikipedia.org/wiki/Nintoku_Seamount

    Nintoku Seamount or Nintoku Guyot is a seamount (underwater volcano) and guyot (flat top) in the Hawaiian-Emperor seamount chain. It is a large, irregularly shaped volcano that last erupted 66 million years ago. Three lava flows have been sampled at Nintoku Seamount; the flows are almost all alkalic (subaerial) lava. [4] It is 56.2 million ...

    en.wikipedia.org/wiki/Allison_Guyot

    Allison Guyot is located in the equatorial Pacific Ocean, [1] part of the western Mid-Pacific Mountains. [13] The Mid-Pacific Mountains contain seamounts which were covered by limestones during the Barremian and Albian (circa 129.4 – circa 125 million years ago and circa 113–100.5 million years ago, respectively [14]). [15]

    MIT Guyot is a guyot in the Pacific Ocean that rises to a depth of 1,323 metres (4,341 ft). It has a 20-kilometre-long (12 mi) summit platform and formed during the Cretaceous in the region of present-day French Polynesia through volcanic eruptions.

    Horizon Guyot is a presumably Cretaceous guyot (tablemount) in the Mid-Pacific Mountains, Pacific Ocean.It is an elongated ridge, over 300 kilometres (190 mi) long and 4.3 kilometres (2.7 mi) high, that stretches in a northeast–southwest direction and has two flat tops; it rises to a minimum depth of 1,443 metres (4,730 ft).
