This article is about a volcanic field that surrounds a lake in Chile, close to the border of Argentina. It has had eruptions over the past few million years and several during the last 10,000 years, and left a number of lava flows and craters which dot and cover the landscape around Laguna del Maule. The last eruption was 2000-1000 years ago but there is still magma underneath the volcano.

Recently (as in, during the 21st century) there has been an intense uplift of the volcanic field, which has attracted interest among the volcanology community and has raised concerns that another eruption may be imminent. Jo-Jo Eumerus (talk) 13:27, 16 July 2020 (UTC)[reply]

Support - Image review by Lee Vilenski

[edit]

May or may not claim wikicup points - maybe?

Comment by Buidhe
  • The image in Geology section is not very helpful to reader understanding. The Nazca plate is not labeled, nor is the location of the volcano marked. I know enough about plate tectonics to guess from the caption that the fault in question is a subduction fault (west?—should be explicitly stated in the article) of the volcano, but it would likely be excessively confusing to a non-expert reader.

    I wouldn't be averse towards ditching it completely. Most of the context there isn't relevant, anyhow. File:Subduction-en.svg might be a touch better. Jo-Jo Eumerus (talk) 20:12, 18 July 2020 (UTC)[reply]

Comments from Ceranthor

[edit]
Lead
  • Looks tight! A few comments.
  • "Volcanic rocks in the field vary from basalt over andesite and dacite to rhyolite" - little vague what you mean here; basalt physically overlying andesite, as well as dacite and rhyolite? Could you clarify?
    Rewrote this; I can see why it would be ambiguous. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • "The field was a source of obsidian with regional importance." - "regional importance" is super vague; historical, economic... what type of importance?
    I don't think one can specify much farther from the archeological record. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
Geography and structure
  • "straddles the Chilean–Argentine frontier" - why trade border for frontier?
    Mostly to avoid repetition. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • " Highway 115 passes through" - links to a disambiguation page
    Done. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • "Highway 115 passes through the northern part of the volcanic field,[6] and the Paso Pehuenche mountain pass is a few kilometres northeast of the lake;[7] the region is otherwise sparsely inhabited[8]" - wait, why would highways/mountain passes indicate that the region is densely populated?
    Not really certain but the point is that besides this road there is not much human activity. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • " The lake has a depth of 50 metres (160 ft),[15] a surface area of 54 square kilometres (21 sq mi),[16] and the surface is at an altitude of 2,160 metres (7,090 ft).[6][17]" - run-on sentence
    Split it up a little. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • " Terraces around the lake indicate that water levels have fluctuated in the past;[20] it is regulated by a dam at the outlet[5] that was built in 1950.[21]" - I assume "it" refers to the lake, but you should avoid using it there. I suggest just replacing it with "the lake"
    Done. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • " Volcanic ash and pumice produced by the eruptions has been found in Argentina.[7]" - does the ref mention how far away?
    No, but another ref does; done. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • "Among the various structures in the volcanic field, Domo del Maule lava dome is of rhyolitic composition and generated a lava flow to the north that dammed the Laguna del Maule." - nitpicky, but no reason for "the" before Laguna imo
    Removed. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • This section could use some copyediting for flow.
    Whittled a bit. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
Geology
  • "Probably due to increased convergence rates of the Nazca and South America plates for the past 28 million years, a phase of strong volcanic activity began in the Andes 25 million years ago." - can you switch the clauses here? I think it would flow better
    Done. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • Could you use parentheticals to briefly describe fault types and the terms mafic and pluton for a lay reader? Linking is fine, but I think a very basic explanation in a few words would be helpful too
    Done. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • Any reason for the long subtitle "Composition of erupted lavas and pyroclasts" rather than just composition or composition of eruptive products?
    Shortened. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
  • "The andesites and basaltic andesites having medium K contents[48] and in the Loma de Los Espejos rocks a SiO

2 content of 75.6–76.7% per weight has been noted.[49]" - very wordy; could shorten and make sharper and more clear

explanations
  • Some footnotes have a space between p. and the page number; some don't. This should be consistent throughout.
    Tried to remedy that, but I am not sure what other text may have been changed in the process. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]
    You broke several |bibcode= parameter values and set author initials P. → p. I have fixed the bibcodes and one of the initials. I'll leave the author initials to you. Search and replace: it works great except when it doesn't. For FACs, editors should ensure that cs1|2 error messaging is enabled. The bibcode problems were clearly marked with Check |bibcode= length error messages.
    Trappist the monk (talk) 14:31, 31 July 2020 (UTC)[reply]
  • Likewise, some footnotes have just initials; some have full author names - should be consistent
    Yeah, not all sources provide that information. Jo-Jo Eumerus (talk) 10:15, 31 July 2020 (UTC)[reply]

As usual, a well-researched article. Prose could use some fine-tuning. Will post more comments after these are fixed up/responded to accordingly. ceranthor 01:46, 31 July 2020 (UTC)[reply]

Coord note

[edit]

I'm adding this to the urgents list for hopefully a few more reviews. Also the source reviews for one. --Ealdgyth (talk) 14:33, 17 August 2020 (UTC)[reply]

Asked on the talk pages of pertinent wikiprojects and will ping Ceranthor again. Jo-Jo Eumerus (talk) 19:53, 20 August 2020 (UTC)[reply]
Hi, despite the above, this hasn't really had sufficient review to determine consensus to promote after remaining open more than two months so I think we need to call a halt and try again after a breather. Cheers, Ian Rose (talk) 13:25, 26 September 2020 (UTC)[reply]

Minor grammar note

[edit]

Should it be "a SiO2 content" or "an SiO2 content"? If it should be read as "silicon dioxide", then use "a". If you read it "ess-eye-oh-two", use "an", because it starts with a vowel sound. – Jonesey95 (talk) 15:57, 28 August 2020 (UTC)[reply]

...honestly I don't know about that. "a sio2" appears to be more commonly used than "an sio2" though. Jo-Jo Eumerus (talk) 19:14, 28 August 2020 (UTC)[reply]

Funk

[edit]
@FunkMonk: Hey there! Do you think you'll be reviewing this soon? --Laser brain (talk) 11:04, 9 September 2020 (UTC)[reply]
Yes, within the week. But I'd of course also like to know if the nominator is watching. FunkMonk (talk) 11:11, 9 September 2020 (UTC)[reply]
@FunkMonk:Yes, I still watch this. Sorry for not actioning this immediately, but I thought you had more comments than these below (which I've actioned). Jo-Jo Eumerus (talk) 19:06, 12 September 2020 (UTC)[reply]
Yep, there will be more as I read through. FunkMonk (talk) 15:28, 13 September 2020 (UTC)[reply]
Everything should generally be linked again at first mention outside the intro too. FunkMonk (talk) 15:28, 13 September 2020 (UTC)[reply]
Hmm, I wonder if this could be explained in the text for layreaders then? FunkMonk (talk) 15:28, 13 September 2020 (UTC)[reply]
Going to be hard since most sources just assume that folks understand. Jo-Jo Eumerus (talk) 16:05, 13 September 2020 (UTC)[reply]
Yep, looks good now. FunkMonk (talk) 01:31, 19 September 2020 (UTC)[reply]
  • "but petroglyphs in Valle Hermoso may depict volcanic activity at Laguna del Maule" They must be very old, anything we can show here?
    Not really; none of the petroglyphs I did see on Google Images have either an implicit or explicit link to volcanism. Jo-Jo Eumerus (talk) 07:21, 18 September 2020 (UTC)[reply]
  • "Present-day threat" seems a bit loaded, if this article is written form a geological standpoint, calling an eruption itself a "threat" seems a bit humanocentric, as the section is not mainly about the human consequences. Maybe it could be called something broader, like "possible future eruptions" or similar?
  • "which surround Laguna del Maule lake" Surround the?
    @FunkMonk:Did these two changes. Jo-Jo Eumerus (talk) 08:34, 19 September 2020 (UTC)[reply]
