About Limalok in brief
Limalok is a Cretaceous-Paleocene guyottablemount in the southeastern Marshall Islands. It is located at a depth of 1,255 metres and has a summit platform with an area of 636 square kilometres. It was probably formed by a volcanic hotspot in present-day French Polynesia. Limalok lies southeast of Mili Atoll and Knox Atoll, which rise above sea level, and is joined to each of them through a volcanic ridge. After volcanic activity ceased, the volcano was eroded and thereby flattened, and a carbonate platform formed on it during the Paleocene and Eocene. The platform sank below sea level 48 ± 2 million years ago during the Eocene, perhaps because it moved through the equatorial area, which was too hot or nutrient-rich to support the growth of a coral reef. Thermal subsidence lowered the drowned seamount to its present depth. The crust underneath these seamounts tends to subside as it cools, and thus the islands and seamsounts sink. The formation of many seamountS can be explained with the theory, in which a hotshot spot leads to the formation of chains of volcanoes along the length of the chain, which get progressively older. One solution to this dilemma may be that one hotspot may be more than one end of the Marshall Islands, and it is also possible that it was affected by hotspotism as the plate moves over the hotspot Seamounts and islands in Marshall Islands do not appear to have originated from simple age-progressive volcanism as it is often inconsistent with this explanation.
The Pacific Ocean seafloor, especially the parts that are of Mesozoic age, contains most of the world’s guyots ). These are submarine mountains which are characterized by steep slopes, a flat top and usually the presence of corals and carbonate platforms. Fringing reefs may have developed on the volcanoes, which then were replaced by barrier reefs as the volcanoe subsided and turned into atolls. The top of LimalOK is 47. 5 kilometres long and broadens southeastward from less than 5 kilometres to more than 24 kilometres, forming a 636-square-kilometre summit platform. Volcanic sediments in the Eastern Mariana Basin may come from this seamount. The seafl floor is 152–158 million years old, but it is possible that Limal ok rises from Cret Jurassic flood basalts rather than the seafl Floor. Limatek was formerly known as Harrie Guyot and is also known as Harriet Guyot; Limalk refers to a traditional chieftess of Mile Atoll.
