Markus-Necker Guyot

A guyot is a flat-topped underwater volcanic mountain, shaped by erosion near sea level and later submerged. Markus-Necker Guyot is notable for its broad summit plateau in the central Pacific.

Markus-Necker Guyot is a seamount in the central Pacific Ocean, far from continental coastlines. Its submerged summit is studied through marine geology and seabed surveys rather than ordinary land-based fieldwork.

Its summit area is known for polymetallic crusts, especially ferromanganese crust deposits. These crusts can contain metals including cobalt, nickel, and rare-earth elements, which makes the site relevant to ocean-resource research.

A volcanic seamount can be planed off by waves when its summit is near sea level, then sink as the oceanic crust cools. That geological history explains the broad, level plateau associated with Markus-Necker Guyot.
