Vlinder Guyot (also known as Alba Seamount) is a guyot in the Western Pacific Ocean. It rises to a depth of 1,500 metres (4,900 ft) and has a flat top covering an area of 40 by 50 kilometres (25 mi × 31 mi).
The Magellan Seamounts extend from to . They include: Govorov Guyot [7. 7]; 121 ± 2.8 to 98.5 ± 1.4 Ma [7]; Ioah Seamount (also known as Ioah Guyot, Ioan Seamount or Fedorov Seamount) . 8]; 87 million years old [8]; Pako Guyot. 9]; 92 million years old [9] but volcanics have been now dated in range 112 to 86 Ma and < 20 Ma in smaller volcanoes on the guyot.

Ioah Guyot is a seamount in the Pacific Ocean, close to the Marshall Islands. [2] Part of the Magellan Seamounts , it is a shield volcano that has erupted alkali basalt and hawaiite 87 million years ago, but may have continued erupting into the Miocene .
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]
The guyot is part of the Magellan Seamounts. [8] The seamount was volcanically active during the Cretaceous-Paleogene [9] 91.3 million years ago [10] and may have formed on a hotspot together with Ioah Guyot and Vlinder Guyot; [11] a late phase of volcanism may have taken place in the Paleocene-Eocene.

Cape Johnson Guyot is also known as Cape Johnson Seamount or Cape Johnson Tablemount. [2] The guyot was named by Harry Hammond Hess, after his ship the USS Cape Johnson; Hess had also named the kind of flat-topped seamount "guyot" and another seamount was named after Hess himself. [3] The seamount was first described in a 1946 publication. [4]
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward.
Resolution Guyot (formerly known as Huevo) is a guyot (tablemount) in the underwater Mid-Pacific Mountains in the Pacific Ocean. It is a circular flat mountain, rising 500 metres (1,600 ft) above the seafloor to a depth of about 1,320 metres (4,330 ft), with a 35-kilometre-wide (22-mile) summit platform.
