Later, pelagic limestones were emplaced on them. A 65 square kilometres (25\u00a0sq\u00a0mi) large area on the northwestern corner of Pako Guyot’s summit plateau is free of sediments.[6]Geology[edit]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.[12] The hotspots that formed Pako Guyot were located in what is today French Polynesia.[6]Volcanic rocks dredged from Pako are of sodium-potassium hawaiitic and trachybasaltic composition[2] and geochemically resemble these erupted by the Rarotonga hotspot.[13]Clays with Cenomanian-age radiolarian fossils cover the entire lower slopes of Pako Guyot.[7]Corals and squat lobsters have been found on the seamount.[14]Ophiuroids, most of which are symbiotic with corals and sponges, live on the seamount and its flanks.[1] Diverse communities including brittle stars, corals, fish, sea anemones, sea cucumbers, sea lilies, sea urchins, shrimp and starfish have been found at its feet, where organic matter accumulates.[3]Ammonites lived on the seamount during the Cretaceous.[15]The seamount features substantial deposits of ferromanganese and phosphorite ores.[2] In 2014, China obtained a contract with the International Seabed Authority allowing for exploration of Pako Guyot for cobalt crusts.[16]See also[edit]References[edit]^ a b Zhang, Dongsheng; Lu, Bo; Wang, Xiaogu; Lin, Shiquan; Wang, Chunsheng (April 2015). “Ophiuroids from the Caiwei(Pako) guyot in the northwest Pacific”.
