{{Location map|Marshall Islands |caption = Location in the Marshall Islands |label = Lomilik |mark = Red triangle with thick white border.svg |coordinates= {{coord|161|37|E|11|42|N|display=inline,intitle|notes=[1]}} }}Lomilik is a seamount in the Western Pacific Ocean, within the exclusive economic zone of the Marshall Islands.[2] It lies to the west of Anewetak atoll{{sfn|Hein|Moon|Lee|Kim|1998|p=2}} and is named after the best fishing site of Anewetak atoll.{{sfn|Hein|Kang|Schulz|Park|1990|p=245}} Lomilik has a {{convert|40|x|15|km}} wide summit terrace with the proper summit at circa {{convert|1500|m}} depth; a scarp separates the two and small hills reach depths of {{convert|1350|m}}. The summit terrace is covered by rocks with ooze in between. A notch in the southern flank of Lomilik was probably created by a landslide.{{sfn|Hein|Moon|Lee|Kim|1998|p=2}}{{sfn|Hein|Moon|Lee|Dowling|1999|p=3}} It is part of the Magellan Seamounts[1] and consists of a Cretaceous volcano with a thin layer of carbonate rocks and ferromanganese.[4] Lami seamount lies northwest of Lomilik.{{sfn|Hein|Kang|Schulz|Park|1990|p=108}} The rocks found on Lomilik consist of basalt and limestone.{{sfn|Hein|Moon|Lee|Kim|1998|p=4}} Fluorapatite, hyaloclastite,[5] mudstone, phosphorite and siltstone have been identified in rocks from the seamount. Manganese nodules have been found on Lomilik[2] and the manganese crusts on the seamount reach thicknesses of over {{convert|10|cm}};{{sfn|Hein|Kang|Schulz|Park|1990|p=32}} the thickest crust recovered from an ocean is a {{convert|18|cm}} thick ferromanganese crust from Lomilik recovered in 1989.{{sfn|Hein|Moon|Lee|Kim|1998|p=2}} The deposits on Lomilik could potentially be mined.{{sfn|Hein|Moon|Lee|Dowling|1999|p=14}} References 1. ^1 {{cite journal |last1=Hein |first1=James R. |last2=Koschinsky |first2=Andrea |last3=Halbach |first3=Peter |last4=Manheim |first4=Frank T. |last5=Bau |first5=Michael |last6=Kang |first6=Jung-Keuk |last7=Lubick |first7=Naomi |title=Iron and manganese oxide mineralization in the Pacific |journal=Geological Society, London, Special Publications |date=1997 |volume=119 |issue=1 |page=127 |doi=10.1144/GSL.SP.1997.119.01.09 |url=http://sp.lyellcollection.org/content/119/1/123.short |language=en |issn=0305-8719}} 2. ^1 {{cite journal |last1=Kim |first1=Jonguk |last2=Hyeong |first2=Kiseong |last3=Jung |first3=Hoi-Soo |last4=Moon |first4=Jai-Woon |last5=Kim |first5=Ki-Hyune |last6=Lee |first6=Insung |title=Southward shift of the Intertropical Convergence Zone in the western Pacific during the late Tertiary: Evidence from ferromanganese crusts on seamounts west of the Marshall Islands |journal=Paleoceanography |date=1 December 2006 |volume=21 |issue=4 |page=2 |doi=10.1029/2006PA001291 |language=en |issn=1944-9186}} 3. ^1 2 {{Cite book|date=2014-01-01|chapter=Deep-Ocean Ferromanganese Crusts and Nodules|chapter-url=https://www.sciencedirect.com/science/article/pii/B9780080959757011116|language=en|doi=10.1016/B978-0-08-095975-7.01111-6|p=274|title=Treatise on Geochemistry|last1=Hein|first1=J.R.|last2=Koschinsky|first2=A.|isbn=9780080983004}} 4. ^1 2 {{cite journal |last1=Hyeong |first1=Kiseong |last2=Kim |first2=Jonguk |last3=Yoo |first3=Chan Min |last4=Moon |first4=Jai-Woon |last5=Seo |first5=Inah |title=Cenozoic history of phosphogenesis recorded in the ferromanganese crusts of central and western Pacific seamounts: Implications for deepwater circulation and phosphorus budgets |journal=Palaeogeography, Palaeoclimatology, Palaeoecology |date=December 2013 |volume=392 |doi=10.1016/j.palaeo.2013.09.012 |url=https://www.sciencedirect.com/science/article/pii/S0031018213004148 |p=294 |language=en |issn=0031-0182}}
