Talk:Tacora

Prominence Discrepancy

Global Volcanism Program doesn't list an edifice height, but the two previously listed sources (PeakList and PeakBagger) list 1721m and 1713m respectively. Both are independently-run sites, with PeakList acknowledging "independent research". The Oregon State University site lists the rounded 1700m, based on a "base level of about 4300m". I'm deferring to significant digits and an established institution, and updating the prominence to 1700m. tgok (talk) 02:00, 27 January 2014 (UTC)

I'll be reviewing this in the next few days. ceranthor 19:15, 7 June 2018 (UTC)

Lead

• "Bordering Peru, it is the northernmost volcano of Chile" - I'd link Peru here
• "Tacora itself is a stratovolcano with a caldera and a crater; it is heavily eroded by glacial activity and its youngest radiometric age is 50,000 years ago." - seems like you're combining too many ideas here; maybe break into a few sentences?
• "north-south alignment" - north-south should have an ENDASH
• "Tacora itself has uncertain reports of historical eruptions and features ongoing fumarolic activity." - to a lay reader, "features ongoing fumarolic activity" is unclear; be more clear to a general reader perhaps?
• Third paragraph is good, but I think it can be combined with the second

All done save the last item; given that the volcano is known for its sulfur mining operations it probably stands better on its own. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Geography and geomorphology

• First and second paragraphs can be consolidated I think.
• "Tacora is part of the Central Volcanic Zone,[4] one out of several volcanic zones of the Andes.[3] The Central Volcanic Zone is one of the world's major volcanic provinces and features both a high density of volcanoes and some of the tallest volcanic edifices in the world.[5]" - too much repetition of the word "zone"
• "The volcano is a cone with a summit caldera that opens northwest and a 500 metres (1,600 ft) wide crater below the summit[3]" - needs an |adj=on parameter for 500 metre
• "scarp[8]." - citation should go after the period
• "Steep mafic" - worth briefly clarifying what mafic means
• "there is trace of a sector collapse scar and of the resulting debris avalanche on the southeastern flank.[10]" - grammatically this seems off; is it supposed to say "there are traces"?
• "Three sets of moraines " - link moraine?
• "Tacora has been prospected for geothermal power generation.[19]" - can you elaborate a bit on this? what did they find? and by whom?

I think it may be better to keep generic geographical from geological information. Will need to go looking for geothermal. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Geology

• "These volcanically active zones are separated by zones where recent volcanism is absent and the subducting plate descends in a much shallower angle.[24]" - maybe replace the second use of 'zones'
• "About 17 volcanoes are at least fumarolically active in northern Chile, with igneous activity limited to about 6" - I'd rm the "at least" here
• " the first of which was dominated by dacitic-rhyolitic ignimbrites and the second by composite volcanoes, with vigorous activity during the Pliocene and Pleistocene.[28]" - might have to reduce some of the jargon here by explaining what "dacitic-rhyolitic ignimbrites" means for example
• "The volcano is constructed by " - comprised of is better
• "andesite and chiefly dacite[10] " - why say chiefly dacite second if it's more dacite than andesite?

Done. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Eruptive history

• "Tacora was active during the Pleistocene and Holocene[4]" - add "epochs" after Holocene
• "The crater is probably the most recent manifestation of volcanic activity, as may be lava flows on the southern flank.[3]" - maybe "along with lava flows" is better than "as may be"

Done. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Mining and sulfur

• "which precipitates the mineral in cavities of rocks" - better as "in rock cavities"
• "A. Barrón, Filomeno Cerda, Luis Koch and Rosa Landaeta owned sulfur deposits on Tacora in 1897" - is the first name not known?

No. Got the other things. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Mythology

• "In local belief, Tacora and Sajama were two mountains in competition between each other for two women" - can cut out "between each other"; also are they actually seen as mountains or as spirits/deities?
• "Tacora subsequently which fled, shedding blood and a piece of its heart.[48]" - don't think you meant to include "which" before "fled"
• "Other" seems like a trivia/cruft section. I think you could combine that section into the mythology section somehow by altering the title of that section a bit

Source isn't specific. I've renamed the "other" section but I am not actually sure if there should be one. Got the other issues. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

References

• Ref 15 shouldn't be capitalized for consistency's sake. Same with refs 20, 31, and 48.
• In refs 18 and 19, why do the bibcode and doi, respectively, skip to a new line? Is that just the formatting on my computer?
• Refs check out. Will do spotcheck later.

Probably a computer thing. Jo-Jo Eumerus (talk, contributions) 20:14, 8 June 2018 (UTC)

Looks great! Once these are fixed, this should be good to pass. ceranthor 17:42, 8 June 2018 (UTC)

@Jo-Jo Eumerus: I'll pass this. I suggest looking to see if there's more available on geothermal resources, but that isn't totally necessary for this becoming a GA. Nice work. ceranthor 20:29, 8 June 2018 (UTC)

"It is worth noting that the 1929 border treaty between Peru and Chile had explicitly placed Tacora's sulfur deposits entirely within Chilean territory."

But why is it worth noting? Ed ^{[talk] [majestic titan]} 23:26, 2 July 2018 (UTC)

Mainly because it looks like it was purposefully done. I am not certain if the wording used is a good wording, though. Jo-Jo Eumerus (talk, contributions) 06:31, 3 July 2018 (UTC)
