Lomilik is a seamount in the Western Pacific Ocean, within the exclusive economic zone of the Marshall Islands. [1] It lies to the west of Enewetak atoll [2] and is named after the best fishing site in Anewetak atoll. [3]
Lomilik has a 40-by-15-kilometre-wide (24.9 mi × 9.3 mi) summit terrace with the proper summit at circa 1,500 metres (4,900 ft) depth; a scarp separates the two and small hills reach depths of 1,350 metres (4,430 ft). The summit terrace is covered by rocks with ooze in between. A notch in the southern flank of Lomilik was likely created by a landslide. [2] [4] It is part of the Magellan Seamounts [5] and consists of a Cretaceous volcano with a thin layer of carbonate rocks and ferromanganese. [6] Lami seamount lies northwest of Lomilik. [7]
The rocks found on Lomilik consist of basalt and limestone. [8] Fluorapatite, hyaloclastite, [9] mudstone, phosphorite and siltstone have been identified in rocks from the seamount. [10] Manganese nodules have been found on Lomilik [1] and the manganese crusts on the seamount reach thicknesses of over 10 centimetres (3.9 in); [11] the thickest crust recovered from an ocean is a 18 centimetres (7.1 in) thick ferromanganese crust from Lomilik recovered in 1989. [2] The deposits on Lomilik could potentially be mined. [12]
