description Limalok Guyot Overview
Limalok Guyot is a flat-topped, Cretaceous-era seamount located in the Pacific Ocean within the Marshall Islands. The underwater mountain is scientifically notable for its large, drowned Eocene coral reefs that cap its summit. These geological features, along with its volcanic foundations, were extensively studied by researchers during scientific ocean drilling expeditions to understand Pacific paleoenvironments.
help Limalok Guyot FAQ
Where is Limalok Guyot located?
Limalok Guyot is an underwater mountain in the Pacific Ocean within the Marshall Islands. A guyot is a seamount with a flat summit, usually shaped by erosion and later subsidence.
Why is Limalok Guyot scientifically notable?
Its summit is capped by large drowned Eocene coral reefs. Those submerged reefs preserve evidence of a time when the seamount's upper surface stood closer to sea level.
How old is Limalok Guyot's volcanic foundation?
Limalok Guyot is described as a Cretaceous-era seamount. Its later Eocene coral cap records a much younger phase of reef growth before the summit sank beneath the ocean.
What is a guyot, and how does Limalok fit the definition?
A guyot is a flat-topped seamount, usually a volcanic island or mountain that subsided below sea level. Limalok fits because its summit is broad and level, with drowned coral reefs marking its former shallow-water environment.
