Horizon Guyot is a presumably Cretaceous guyot in the Mid-Pacific Mountains, Pacific Ocean. It is an elongated ridge, over 300 kilometres long and 4. 3 kilometres high, that stretches in a northeast-southwest direction and has two flat tops. It rises to a minimum depth of 1,443 metres –1,440 metres.
About Horizon Guyot in brief
Horizon Guyot is a presumably Cretaceous guyot in the Mid-Pacific Mountains, Pacific Ocean. It is an elongated ridge, over 300 kilometres long and 4. 3 kilometres high, that stretches in a northeast-southwest direction and has two flat tops. It rises to a minimum depth of 1,443 metres –1,440 metres. The seamount is named after the research vessel RV Horizon and is also known as Horizon Ridge, Horizon Tablemount, Gora Khorayzn and Гора Хорейзн. It was probably formed by a hotspot, but the evidence is conflicting. Volcanic activity occurred during the Turonian-Cenomanian eras 100. 5–89. 8 million years ago and another stage has been dated to have occurred 88–82 million years ago. Horizon Guyot became a seamount during the Coniacian-Campanian period. It trends in a southwest-northeast direction with an orientation matching that of other structures in the region such as fracture zones on the seafloor. Faulting has been observed on the western side of the seamount. On the eastern summit platform there are buried terraces beneath the sediment cover. Sediment layers cover almost the entire summit and consist mainly of sand, with clay and silt making up a minor part. The Pacific Ocean contains many Talus blocks up to 5 metres in size in the West. Landsliding is probably triggered by earthquakes after the landslides either stay coherent and do not travel far but some advance quickly and far out of the area they are in.
In certain places cobbled boulders and cobbles cover out some places in some places in certain places. The seaflour around the West Guyot shows evidence of repeated mass failures; including hummocky terrain, scarps and slump blocks, which are on average 30 metres thick on average thick. Unlike conventional island chains in the Pacific Ocean, the Mid.Pacific Mountains feature an oceanic plateau with guyots ) which become progressively younger towards the east. Other guyots in the mid-Pacific mountains are Sio South, Darwin, Thomas, Heezen, Allen, Caprina, Jacqueline, Allison and Resolution. South of HorizonGuyot, deep water in the \”Horizon passage\” leads into the Line Islands and Horizon GuyOT is sometimes considered to be a member of that chain. The ridge is a ridge 75 kilometres wide and over 300km long; Horizon Guyhot is the largest seamount in the Middle-Pacific Mountain. It has two summit platforms lie on the ridge. The eastern one is the larger of these platforms and the western oval-shaped platform lies close to the western end of the ridge, These platforms are relatively flat and are surrounded by a slope break beyond which the guyot falls off steeply to the surrounding abyssal plain. This appearance characterises Horizon Guyots as a guyot although the elongated shape.
