Did You Know
A fact from this article appeared on Wikipedia's Main Page in the "Did you know?" column on June 29, 2016.
The text of the entry was: Did you know ... that Incapillo (pictured) is the highest explosive caldera in the world and may still be hydrothermally active?
Current status: Featured article

Spelling

[edit]

Inka Pillu is the correct spelling of the Quechua term. It should appear in the text adding a reference (relevant dictionary). This information does not belong to the geography section. -- CaTi0604 (talk) 05:41, 16 June 2016 (UTC)[reply]

General
  • No copyvio/dablink/external link issues
  • No caption for the one image in the article? (not the infobox ones)
Lead
  • Mind adding a few words on what a caldera is?
Geography and structure
  • Wikilink caldera
  • also known as Bonete caldera Should go to the 1st para, where you discuss the etymology
Geology
  • Wikilink Nazca plate, isotope
  • Wood et al. in 1987 Not the way we usually write things here. You can say "a 1997 study" or "Wood and colleagues in 1997" (but then you should give the full name of Wood and add who he is).
Climate, hydrology and vegetation
  • Does "grass" really need a link?
History
  • "mafic" is a duplink
  • "distal" may be a tough term
  • comparable to the Katmai ignimbrite ..."that of" the Katmai...
  • What are "Aeolian effects"?

Rest looks good. Sainsf (talk · contribs) 08:19, 22 June 2016 (UTC)[reply]

Cerro Bonete Grande

[edit]

Cerro Bonete Grande is a redlink. Did you mean to link it to Cerro Bonete like you did with Cerro Bonete Chico? Morfusmax (talk) 21:46, 29 June 2016 (UTC)[reply]

Review

Hi Jo-Jo, see my comments below:

Introduction
  • "Subduction of the Nazca Plate beneath the South America plate" → "Subduction of the Nazca Plate beneath the South American Plate".
Geography and structure
  • "The three adjacent volcanic centres of Monte Pissis (6,882 metres (22,579 ft)), Cerro Bonete Grande (6,436 metres (21,115 ft)), and Cerro Bonete Chico (6,759 metres (22,175 ft)) are also considered part of this volcanic complex and are among the highest on Earth." Would it be better if "this volcanic complex" was changed to "the Incapillo volcanic complex"?
  • "These centres surround the ignimbrite and lava domes." I assume this is the Incapillo ignimbrite? The lead mentions two ignimbrites: the Incapillo ignimbrite and the Katmai ignimbrite.
  • "Around the caldera lie 40 lava domes, distributed in a northwest-southeast pattern." Would it be better if this sentence was reworded to "Surrounding the caldera are 40 lava domes, distributed in a northwest-southeast pattern."?
  • "The domes have heights of 100–600 metres (330–1,970 ft), many feature a basal apron of about 1 kilometre (0.62 mi) width consisting of erosional material." Would it be better if this sentence was reworded to "The domes have heights of 100–600 metres (330–1,970 ft), many of which feature a basal apron about 1 kilometre (0.62 mi) wide consisting of erosional material."?
  • "This 350 metres (1,150 ft) or 13 metres (43 ft) deep lake" → This 350-metre (1,150 ft) or 13-metre (43 ft) deep lake
Geology
  • "The Nazca plate subducts beneath the South America plate" → "The Nazca Plate subducts beneath the South American Plate".
  • "The subduction results in volcanism along the occidental Cordillera 240–300 kilometres (150–190 mi) east of the trench formed by the subduction." I'm guessing "occidental" should be capitalized since Cordillera Occidental is a proper name.
  • "About 50 kilometres (31 mi) west of Incapillo lies the Maricunga Belt, where volcanism started 27 mya and involved phases of ignimbritic and stratovolcanic activity, including Copiapo volcano, until activity ceased with the last eruption of Nevado de Jotabeche 6 mya." It would probably be better to the general reader if 27 mya and 6 mya were spelled out (i.e. million years ago instead of mya).
Local
  • "Incapillo is on a 70 kilometres (43 mi) thick crust, among the thickest in volcanic regions of the Earth." → "Incapillo is on 70-kilometre (43 mi) thick crust, among the thickest in volcanic regions of the Earth."
  • "At the latitude of Incapillo, the Nazca plate subducting beneath the South America plate abruptly shallows towards the south." This should probably be "At the latitude of Incapillo, subduction of the Nazca Plate beneath the South American Plate abruptly shallows towards the south."
  • "Incapillo is part of a volcanic system active between 3.5 and 2 mya that includes Ojos del Salado and Nevado Tres Cruces." See above.
  • "Another volcanic trend considers Incapillo as part of a northeast–southwest trend with Cerro Galan and Cerro Blanco." What is meant by "volcanic trend" at the start of this sentence? From what I understand, a volcanic trend is a line of volcanoes but how does a line of volcanoes consider anything?
  • "The formation of the older lava domes may have been influenced by buried faults or the supply systems of the older Pissis and Bonete Chico volcanoes." What older lava domes?
    These of Incapillo. Jo-Jo Eumerus (talk) 05:57, 20 July 2023 (UTC)[reply]
History
  • "Activity at Incapillo commenced shortly after the end of the Maricunga Belt volcanism and occurred first at Monte Pissis between 6.5 and 3.5 mya." See above.
  • "Later volcanism occurred south of Incapillo 4.7±0.5 mya, at Sierra de Veladero 5.6±1–3.6±0.5 mya, and in the region of Cerro Bonete Chico 5.2±0.6–3.5±0.1 mya." Plus and minus symbols are normally spaced rather than grouped together.
  • "Some of the 3–2 mya Pircas Negras mafic andesites appear to be associated with the Incapillo volcanic complex." See above.
  • "Specific ages of the Pircas Negras flows in the Incapillo region include 4.7±0.5 mya, 3.2±0.3 mya and 1.9±0.2 mya." See above.
  • "Later, andesitic-rhyolitic volcanism formed ignimbrites and lava domes 2.9±0.4–1.1±0.4 mya, with the youngest pre-caldera dome being 0.873±0.077 mya old." See above.
  • "Thicknesses range from 250 to 10 metres (820 to 33 ft); the ignimbrite is underlain by a lithic-and-ash rich surge deposit with a thickness of 5 centimetres (2.0 in)." Should 250 to 10 metres (820 to 33 ft) be 10 to 250 metres (33 to 820 ft)?
  • "Ages have been found of 0.52 ± 0.03 and 0.51 ± 0.04 mya ago." Maybe "Ages of 0.52 ± 0.03 and 0.51 ± 0.04 million years have been found."?
  • "It is a rhyodacitic to rhyolitic ignimbrite with a high crystal and pumice and low lithic content." How about "It is a rhyodacitic to rhyolitic ignimbrite with high crystal and pumice content and low lithic content."?
  • "The debris flow does have a different composition from the main Incapillo ignimbrite, as it contains red-brown dacite and clasts." I would slightly reword it to "The debris flow has a different composition from the main Incapillo ignimbrite as it contains red-brown dacite and clasts."
  • "It has a massive ungraded composition and is likely a lahar or debris flow deposit, probably influenced by glacial or crater lake water." It has already been claimed in previous sentences that Veladero is a debris flow. Is it necessary to claim this again?
    I don't think that we have already said it was a lahar or glacial thing? Jo-Jo Eumerus (talk) 05:57, 20 July 2023 (UTC)[reply]
    No. Volcanoguy 14:16, 20 July 2023 (UTC)[reply]
  • "There are no dates available for post-caldera lava domes, which probably arose from magma ascending through the caldera forming conduits, seeing as these domes are found only inside the caldera." Hyphen between caldera and forming.

On a side note it would probably be better if the History section had a more precise title, something like Volcanic history. History can refer to a lot of things. Volcanoguy 22:12, 19 July 2023 (UTC)[reply]

Did most of the changes. Jo-Jo Eumerus (talk) 05:57, 20 July 2023 (UTC)[reply]
All images need alt texts. Volcanoguy 14:17, 20 July 2023 (UTC)[reply]
Done. Jo-Jo Eumerus (talk) 19:03, 20 July 2023 (UTC)[reply]
I'm thinking the Geologic history section would be better as a subsection of Geology since it's describing geology? Volcanoguy 22:49, 20 July 2023 (UTC)[reply]
In most articles, they are considered separate. Jo-Jo Eumerus (talk) 05:51, 21 July 2023 (UTC)[reply]
I'm not aware of a guideline claiming articles should be structured the same as other articles. Geologic history is a subtopic of geology and thus would make more sense as a subsection of that topic. Volcanoguy 12:40, 21 July 2023 (UTC)[reply]
I don't think this requires a guideline. It's just a writing choice, and I find keeping the eruption history separate from the geology eminently reasonable. Jo-Jo Eumerus (talk) 14:16, 21 July 2023 (UTC)[reply]
