I'll review this. Mike Christie (talk - contribs - library) 17:33, 17 February 2018 (UTC)

I'll copyedit as I read through; please revert as necessary if I screw anything up.

• The lead seems a bit short, particularly as much of the first paragraph gives information about the CVZ rather than specifically about the subject of the article.

Expanded it a bit.

• Should the lead start "The Purico complex is..."? You use "The Purico complex" later in the article. Similarly, should it be "The Licancabur volcano was constructed..."?

Yes, I think so, but Licancabur should stay as it is.

• Can we get a caption for the panorama just above the Geology section?

On the basis of the file description, it can be done, although there won't be a source for this.

• To the west, the shield drops down to a bajada close to the margin of the Salar de Atacama, a bajada being a structure formed by debris flows and gravel fans: suggest "To the west, close to the margin of the Salar de Atacama, the shield drops down to a bajada (a structure formed by debris flows and gravel fans)".

Done.

• Clockwise starting from the west this semicircle includes: "includes" needs a subject; perhaps "Clockwise starting from the west this semicircle the complex includes"?

  I misread this sentence; it's fine as is. Mike Christie (talk - contribs - library) 15:51, 18 February 2018 (UTC)

• the 5,262, 5,462 metres (17,264, 17,920 ft) Cerro Aspero-Cerro Putas (23°5′0″S 67°42′0″W and 23°6′0″S 67°43′0″W) to the south: this is ugly and very hard to read.

Fixed.

• [1] is a dead link; not an issue for GA, but you may want to fix it. It's in footnote 41.

Fixed.

• A north-south trending system of fractures and conspicuous normal faults cuts across the western margin of the Purico complex in north-south direction: repeats "north-south".

Removed.

• Characteristic for the Purico ignimbrite are the so-called "banded" pumice: should be "is the", unless pumice is implicitly plural here.

Changed.

• Such hydrothermal alteration processes are also the origin of the sulfur deposits at Purico and other volcanoes in the world: why mention other volcanoes here, and almost nowhere else? This is surely an obvious observation -- almost any process described in this article applies to volcanoes elsewhere.

Removed.

• Aspero was considered to be of Holocene age; later dates of 180,000 ± 20,000 years ago were obtained on Aspero and Chascon: assuming I'm interpreting this correctly, I suggest "Aspero was once considered to be of Holocene age; later, dates of 180,000 ± 20,000 years ago were obtained on Aspero and Chascon". The comma after "later" avoids the reading of "later dates".

Changed.

@Mike Christie: Answered. Jo-Jo Eumerus (talk, contributions) 15:53, 18 February 2018 (UTC)

Good enough to promote. I'll leave the panorama caption to your judgement. Mike Christie (talk - contribs - library) 16:16, 18 February 2018 (UTC)
