Cerro Panizos[edit]

Featured article candidates/Cerro Panizos/archive1

Nominator(s): Jo-Jo Eumerus (talk) 07:12, 16 May 2024 (UTC)[reply]

This article is about a not-quite shield volcano in Argentina. It is not a particularly remarkable volcano, other than the fact that it was discovered from space imagery and that it is a large volcano in the wider Altiplano-Puna volcanic complex. Jo-Jo Eumerus (talk) 07:12, 16 May 2024 (UTC)[reply]

Image review

File:LandsatLook_Viewer_Cerro_Panizos_ignimbrite_shield.png: source link is dead. Nikkimaria (talk) 05:15, 18 May 2024 (UTC)[reply]

Replaced link, although I don't remember which options I chose on the webpage to find the image. Jo-Jo Eumerus (talk) 06:07, 18 May 2024 (UTC)[reply]

Comments from Z1720[edit]

Non-expert prose review.

No concerns about the prose. I made minor edits to the article: feel free to revert.
In the "Sources", Mazzoni, Mario M. (1989) and Vaquer, José María; Eguia, Luciana; Carreras, Jesica (2018) have titles in all caps, which per MOS:ALLCAPS should be in sentence case.
Done. Jo-Jo Eumerus (talk) 06:40, 25 May 2024 (UTC)[reply]
Infobox checked and no concerns.

Lede check:

"Subduction of the Nazca Plate beneath the South American Plate" is said in the lede, but I think the article body says that the subduction is under South America, with no mention of it being a plate. Should this be more explicit in the body, maybe wikilinked in the body?
Put "South America" instead. Jo-Jo Eumerus (talk) 06:40, 25 May 2024 (UTC)[reply]
In the lede: "The formation of the APVC has been linked to the existence of a giant magmatic body in the crust of the Andes." From what I gather from the body, this magmatic body is the Altiplano-Puna Magma Body. Should this be wikilinked in the lede? And should the lede specify that the body is in the Central Andies (and not underneath the whole thing?)
Implemented. Jo-Jo Eumerus (talk) 06:40, 25 May 2024 (UTC)[reply]

Those are my comments. Please ping when the above are addressed. Z1720 (talk) 01:18, 25 May 2024 (UTC)[reply]

Support. My concerns have been resolved. Z1720 (talk) 15:06, 25 May 2024 (UTC)[reply]

MyCat[edit]

Panizos, Vilama, Cerro Guacha and last Uturuncu, which shows evidence of ongoing activity - which one does "which" refer to? If it's Uturuncu, then "the last of which" is better
Specified. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
For some reason the coords of the highest point aren't showing for me- it's just blank next to "Coordinates"
Mm, they do show for me. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]

Weird then- guess my viewer is just being odd MyCatIsAChonk (talk) (not me) (also not me) (still no) 11:17, 11 June 2024 (UTC)[reply]
Cerro Panizos[b] proper is a 5,228 metres (17,152 ft),[8] 5,360 metres (17,590 ft) or 5,494 metres (18,025 ft) high[9] lava dome in the southeastern semicircle - my lack of geology knowledge will show, but why are there three different heights here? Isn't this referring to the height of Cerro Panizos?
There is more than one elevation estimate - these mountains aren't frequently mapped and measured. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
In para 1, all those references constantly interrupting sentences confuse me- I know that it's ok MoS-wise, I just prefer to keep them to the end. There are so many present here that I worry about others getting confused too
- Ditto for some others, like the parentheses in para 3 of "Geology"
That makes it more difficult to source a specific part, though. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
Efn c doesn't really make sense to me- clarify with some geology knowledge perhaps?
Changed this. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
They run mostly to the east - I'd avoid using "they" since multiple objects are mentioned in the previous sentence
Done. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
Quebrada Cienago[d], - put efn outside of comma
That makes it look like a citation, which this efn isn't. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
A branch of the Inca road system passed over the volcano, which features several archeological sites - what does which refer to? The road system as a whole? The volcano?
Recast. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
It looks like a lot of the first three paras of "Geology" are about the CVZ, not specifically about the Cerro Panizos- how is Panizos relevant here?
Aye, that's contextual information as Panizos is part of the APVC and CVZ so a lot of this is pertinent. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
Numerous ignimbrites were emplaced between 25 and 1 million years ago - usually when I see a date range written out like this, the smaller period goes first and the larger period second
I got the opposite impression - older date first. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
The last eruptions took place 271,000 and 85,000 years ago at Uturuncu and Cerro Chascon-Runtu Jarita complex, - and the Cerro Chascon-Runtu complex...?
Fone. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]
Some of the sources have no translated title, like Guzmán et al and Mazzoni and others (I would add the titles myself if my Spanish was any good, but I trust you can since you cited them)
Done. Jo-Jo Eumerus (talk) 07:00, 11 June 2024 (UTC)[reply]

Jo-Jo Eumerus, that's all I got- I also split the sources list into two columns so it doesn't take up as much space (feel free to revert if you oppose). Excellent work! MyCatIsAChonk (talk) (not me) (also not me) (still no) 21:16, 10 June 2024 (UTC)[reply]

All good on everything, though I do have one comment on the refs. Is citing each individual part of a sentence differently a typical thing in geology articles? I ask this genuinely- in the biographies and other articles I've written, having multiple refs at the end of a sentence is just fine, and IMO makes it more readable. MyCatIsAChonk (talk) (not me) (also not me) (still no) 11:19, 11 June 2024 (UTC)[reply]

I don't think that's a question of article topic and more of who writes articles. I prefer this style b/c it's easier to verify (and correct) statements when you only have to check one source. Jo-Jo Eumerus (talk) 05:57, 12 June 2024 (UTC)[reply]

Makes sense then- happy to support! Also, I need a source review on an FAC nom of my own, and would appreciate one if you get any time. Thank you! MyCatIsAChonk (talk) (not me) (also not me) (still no) 19:56, 12 June 2024 (UTC)[reply]

Volcanoguy[edit]

Introduction

"it produced the large volcanic calderas Panizos, Vilama, Cerro Guacha and Uturuncu". The Uturuncu article claims the latter as a stratovolcano rather than a caldera.
"Panizos is the source of two major ignimbrites, the older Cienago Ignimbrite and the more recent Panizos Ignimbrite." Shouldn't the comma be a colon?
No, I don't think so? Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]

Geography and geomorphology

"The volcano is a 40 kilometres (25 mi) wide" → 10-kilometre-wide (6.2 mi).
"surrounding a 10–15 kilometres (6.2–9.3 mi) wide lava dome semicircle" → 10–15-kilometre-wide (6.2–9.3 mi).
"Cerro Panizos proper is a 5,228 metres (17,152 ft), 5,360 metres (17,590 ft) or 5,494 metres (18,025 ft) high lava dome in the southeastern semicircle." → "5,228-metre (17,152 ft), 5,360-metre (17,590 ft) or 5,494-metre-high (18,025 ft)
"The other domes are the 5,480 metres (17,980 ft), 5,490 metres (18,010 ft) or 5,228 metres (17,152 ft) high Cerro Cuevas, 5,504 metres (18,058 ft) high Cerro Crucesnioc/Crucesnioj/El Volcán, 5,390 metres (17,680 ft) high Cerro Vicunahuasi west and 5,540 metres (18,180 ft) high Cerro La Ramada/Cerro Ramada north of Cerro Panizos." Same as above.
"The 5,158 metres (16,923 ft) high Limitayoc". Same as above.

Hydrology and human geography & history

"Panizos can be accessed through these valleys." Since no valleys are mentioned before this sentence it would probably be better if were reworded as "Panizos can be accessed through the valleys of these streams."

Climate, flora and fauna

"The region is a desert, with the only vegetation consisting of cushion plants, grasses and shrubs." It has already been stated at the beginning of this section that the region is a desert.

Geology

"reaching 6,000 metres (20,000 ft) height". I think you mean 6,000 metres (20,000 ft) in height.
Used a different formulation. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"Neogene-Quaternary volcanic rocks". I'm not sure but I think the hyphen should be an en dash here.
Not sure myself, so leaving this for now. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"Lascar is the most active of them". Maybe swap "is" with "being"?
"The largest assembly of volcanoes in the CVZ is the 70,000 square kilometres". 70,000-square-kilometre (27,000 sq mi).
"Within the crust under the APVC is the Altiplano-Puna Magmat Body". Magmat → Magma.
"At 9–31 kilometres (5.6–19.3 mi) depth". 9–31-kilometre (5.6–19.3 mi).
"One northeast-southwest trending line". En dash.
"Smaller scale structures at Panizos may reflect north-south and eastsoutheast-westnorthwest trending lineaments". En dashes and "eastsoutheast" and "westnorthwest" should be "east-southeast" and "west-northwest".

Geochronology

"Volcanic activity began during the Jurassic". Volcanic activity of what? The Central Volcanic Zone?
Specified. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"During the late Miocene, subduction under the Puna". It's not clear what "Puna" is referring to here. Is it the Altiplano-Puna high plateau or the Altiplano-Puna volcanic complex?
"Volcanic activity shifted east into the Puna". Same as above.
The Puna region. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"With the bulk dating to the late Miocene to Pliocene". I think the first "to" should be changed to "from".
"Tara and Puripicar Ignimbrites". I'm not sure if "ignimbrites" should be capitalized here.
I think in these cases we do. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"In Bolivia, about 8-5 million years ago Kari-Kari was active, 8.4-6.4 million years ago Morococala, 8-5 million years ago Los Frailes". En dashes.
"Volcanism declined during the past 4 million years". Declined where?

Composition

"And orthopyroxene rare". I think you mean are rare.
"Gold and silver deposits are found on the volcano, and an occurrence of antimony-copper-uranium has been described at Paicone." Has mineral exploration been done at the volcano?
Probably, but the sources don't specify. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]

Eruption history

"12.4 million years old Cusi Cusi ignimbrite". 12.4-million-year-old.
"It is the source of two major ignimbrites: The first". I'm not sure if there should be a capital letter after the colon.
I think it should. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]
"a total volume >300 cubic kilometres (72 cu mi)". A total volume of more than 300 cubic kilometres (72 cu mi).
"The >650 cubic kilometres (160 cu mi) Panizos (or Panizos II) Ignimbrite". The more than 650-square-kilometre (250 sq mi) Panizos (or Panizos II) Ignimbrite.
"The Panizos ignimbrite consists of crystal-rich". Should ignimbrite be capitalized here since Panizos Ignimbrite appears to be the name of an ignimbrite deposit?
"The Panizos ignimbrite is one of several "super-eruptions" in the Central Andes". See above and may be "is" should be replaced with "represents" since ignimbrite deposits are not eruptions on their own.
"Both units of the Panizos ignimbrite". See above.

That's all I've got. Volcanoguy 20:30, 16 June 2024 (UTC)[reply]

Done save as commented. Jo-Jo Eumerus (talk) 07:22, 20 June 2024 (UTC)[reply]

Going to note here for @FAC coordinators: that I'll be spottily present in the next few weeks, so they can't count on me for source reviews during this time frame. I'll try to keep up with this FAC. Jo-Jo Eumerus (talk) 19:45, 16 June 2024 (UTC)[reply]
