I will review this.  ceran  thor 18:28, 9 May 2019 (UTC)

Prose

 * Lead
 * "Limalok lies southeast of Eniwetok which rise above sea level and Lo-En is almost connected to it through a ridge." - Think it should be "which rises". Might also add a comma before "and Lo-En"
 * Corrected and replaced "Limalok" with "Lo-En". Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "After the volcanic episode," - Wait, so the shield volcano there was formed by a single eruption? Can you clarify?
 * No, I was meaning after the volcanic phase of Lo-En's existence. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "the seamount was submerged by Turonian times" - "submerged by" makes it read like the "times" were responsible for it going underwater. I think you should rephrase to make this read a bit more clearly for non-native English speakers
 * Rewrote a bit. Is it better now? Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * Link carbonate and sedimentation


 * Name and research history
 * "Lo-En is a reference to the hibiscus tree.[2]" - how so? You should state that explicitly in the text
 * The source isn't terribly detailed and as far as I can tell it is the only one on Google that discusses the name at all. I get the impression that Marshallese toponyms are pure oral tradition with no written records at all, except for this source. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "This seamount was targeted for drilling in the Ocean Drilling Program.[4] - any idea when this was?


 * Geography and geology
 * " Lo-En is elongated in north-south direction[6] and has a flat top[9] with dimensions of 30 by 40 kilometres (19 mi × 25 mi)[10] and a surface area of 823 square kilometres (318 sq mi),[11] it is a typical guyot.[12] " - this last bit makes it a run-on. Could be its own, albeit very short, sentence.
 * I've split it up. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "A volcanic pinnacle is embedded in the sediments on top of Lo-En, it is either a volcanic formation that resisted erosion or a volcanic vent that was active after Lo-En was submerged,[13] there are other cones which emerge from the sediments[14] and which appear to be of volcanic origin in light of the dredged rocks, as well as lobate structures." - also a run-on, but easy fix; just add a period after "Lo-En was submerged" and then capitalize "there"
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "Terraces occur on Lo-En's southwestern rim[10] and may be products of landsliding.[15] " - Never seen "landsliding" before; why not just landslides?
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "The seamount is normally magnetized[3] and it features distinct forms when examined magnetometrically.[16]" - to a lay reader, this would be confusing. Maybe outline (briefly) what normal magnetization means?
 * Link carbonate; pelagic zone too perhaps?
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "Lo-En shares its volcanic edifice with Eniwetok,[22] a northern spur from Lo-En almost reaches Eniwetok[6] while another spur emerges in south-southeast direction[10] and is about 14.5 kilometres (9.0 mi) long.[23]" - Should be a semicolon after the first "Eniwetok" rather than a comma
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "Candidate hotspots responsible for the formation of Lo-En are the Macdonald hotspot which passed close to Lo-En between 115-105 million years ago and the Rarotonga hotspot and Rurutu hotspot, both of which were at Lo-En between 90 and 74 million years ago,[35] the first two also have the strongest geochemical similarity to Lo-En.[36] " - last bit "the first two..." is a run-on. Also, were they at Lo-En or nearby? Not sure that's a precise way of saying it, to say they were "at" the guyot?
 * Split. I don't think that there is much of a distinction in this context; correlating past seamounts to present-day hotspots is always a bit inexact, also because hotspots have a horizontal extent. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "In the case of Lo-En, volcanism on the Ogasawara Fracture Zone may also have contributed to its formation[7] considering that it is much older than surrounding seamounts.[1]" - does the second it refer to the volcanism or Guyot? Clarify please!
 * Seamount; clarified this. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "About 8 hotspots have formed a large number of islands and seamounts in that region, with disparate geochemistries,[38] that geological province has been called "South Pacific Isotopic and Thermal Anomaly" or DUPAL anomaly.[39]" - the last bit (After "that geological province...") doesn't quite fit grammatically with the rest of the sentence.
 * Um, to me it seems correct. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "Strong alteration has occurred[42] " - might be worth linking Mineral alteration
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * Geologic history
 * "The geologic history of Lo-En seamount is relatively poorly known,[44] paleomagnetic data have been used to infer an age of 45-85 million years ago for the seamount.[45]" - need a semicolon rather than a comma after "poorly known"
 * Done. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "It took about 2 to 7 million years " - elsewhere you've used dashes for ranges; you should try to stay consistent with that if you want to take this to FAC eventually
 * Fixed, but IMO it's a bit short for FA status. The other two articles I plan to bring there - Horizon Guyot and Resolution Guyot - have a lot more written about them. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)


 * "nannofossils" - Is it spelled "nanno" or meant to be "nano"?
 * "Nanno". Yes, I was surprised by this as well. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)

Images

 * File:Micronesia and Marshall islands bathymetry, Lo-En (Hess) Guyot.png - checks out
 * File:Marshall Islands location map.svg - seems fine
 * File:Hotspot(geology)-1.svg - seems fine
 * File:Pacific Basin Island Geography Hotspots.jpg - not totally sure about this one; are we sure it's self-made? Also, could you make it slightly larger within the text?
 * Good question. The other uploads by that user do not raise suspicion, however. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)

This is in good shape. Prose needs some polishing but nothing too concerning.  ceran  thor 16:41, 10 May 2019 (UTC)
 * Responded to most points, I think. Jo-Jo Eumerus (talk, contributions) 21:00, 10 May 2019 (UTC)
 * Great. I think the "after that" bit is just a run-on. Any update on the timing comment you didn't respond to?  ceran  thor 13:28, 13 May 2019 (UTC)
 * Resolved these two comments. Jo-Jo Eumerus (talk, contributions) 16:39, 13 May 2019 (UTC)
 * Great, passing this now.  ceran  thor 17:14, 13 May 2019 (UTC)
