Anahim Volcanic Belt

Hi Sémhur, just thought that I would point out an error on File:Anahim Volcanic Belt-en.svg. The Gale Passage and Bella Bella dike swarms are both treated as being 13 million years old, which is incorrect. On a map in this book (page 261) it says the Gale Passage swarm is 13 million years old and the Bella Bella swarm is 12 million years old. Also, your map of the Anahim Volcanic Belt does not include the King Island Pluton. According to this journal it is 10 million years old. A map of the pluton location can be found on page 899. Regards. Volcanoguy (talk) 17:19, 8 January 2016 (UTC)

Anyone there? Volcanoguy (talk) 06:51, 14 January 2016 (UTC)

Hello Volcanoguy. Thanks for the help to improve this map. Nevertheless:

• In the map of "Mantle Plumes: Their Identification Through Time", page 261: the Gale Passage and Bella Bella dike swarms have both 13 million years old, really. The 12 MY event is just outside right of the B map. And I don't know exactly what is this event, because the book didn't mention that. May be somewhere in King Island, or in the mainland between Johnson and Fisher channels?
• I have no access to the article "The western Anahim Belt: root zone of a peralkaline magma system", in the "Canadian Journal of Earth Sciences" website. Apparently, only Pay-Per-view or registred user is possible; perhaps you tell me the location of the pluton location?

Regards, Sémhur (talk) 19:46, 24 January 2016 (UTC)

I have found also this, but I don't know what is the star between the dike swarms and Rainbow Range, and the age of this event. Sémhur (talk) 20:23, 24 January 2016 (UTC)

@Sémhur: Hi;

• The map of "Mantle Plumes: Their Identification Through Time" is most likely a misplacement. I assume this because in the article "The western Anahim Belt: root zone of a peralkaline magma system" there is a table of potassium–argon dated rocks for the Itcha Range, Ilgachuz Range, Rainbow Range, King Island Pluton and the Bella Bella swarm. In the table it gives ages of 10 million years for the King Island Pluton and 12 million years for the Bella Bella swarm.
• The King Island Pluton is a linear structure extending from 52°06'55.27"N, 127°50'30.28"W to 52°13'33.11"N, 127°17'05.27"W.

Regards, Volcanoguy (talk) 12:42, 25 January 2016 (UTC)

 Done. And about the star in the last map I've found, any idea? It seems to be near w:Bella Coola. Sémhur (talk) 20:17, 25 January 2016 (UTC)

@Sémhur: So far I haven't found what that star is marking. I tried accessing the source but it requires a subscription to Bulletin of the Seismological Society of America. There are a few other volcanoes that could be added on the Anahim Belt map:

• w:Anahim Peak: 52°45'28"N, 125°37'31"W (6.7 Ma)
• w:Baldface Mountain: 52°45'35"N, 124°31'53"W (2.52-2.37 Ma)
• w:Whitetop Mountain (British Columbia): 52°38'55"N, 124°33'21"W

The article "The western Anahim Belt: root zone of a peralkaline magma system" gives full age ranges for the Rainbow, Ilgachuz and Itcha ranges:

• w:Rainbow Range (Chilcotin Plateau): 8.7-7.2 Ma
• w:Ilgachuz Range: 6.1-4.0 Ma
• w:Itcha Range: 3.5-1.1 Ma

Regards, Volcanoguy (talk) 22:33, 25 January 2016 (UTC)

Sorry Sémhur; the article gives 10.3 Ma for the King Island Pluton, not 10 Ma. This paper gives an age range of 13-10.3 Ma for the King Island Pluton and an age range of 14.5-12.5 Ma for the Bella Bella swarm. I am kind of skeptical about the later age range because it would also include the Gale Passage dike swarm since the "Mantle Plumes: Their Identification Through Time" book gives an age of 13 Ma for it. Maybe it would be best to take out "Gale Passage dike swarm" and replace "Bella Bella dike swarm" with "Bella Bella and Gale Passage dike swarms". The Gale Passage dike swarm can't be older than 14.5 Ma because it was during this time that the Anahim hotspot began to pass under the North American continent.

Volcanoguy: is it good now ? Sémhur (talk) 20:30, 27 January 2016 (UTC)

Sémhur: looking good, although you didn't add the age range for the King Island Pluton (13-10.3 Ma). I will update you when I find the age for Whitetop Mountain. You can delete the White Creek and Holte Creek cones since they are not used names. Satah Mountain is 1.83–1.77 Ma. Volcanoguy (talk) 23:26, 27 January 2016 (UTC)

Nazko Cone is 0.34-0.007 Ma. Volcanoguy (talk) 23:42, 27 January 2016 (UTC)

 Done. About White Creek and Holte Creek cones, I have found them in the (former?) Catalogue of Canadian volcanoes (Natural Resources Canada). Althought there ages was weird. You can still find that names here or there (Synonyms & Subfeatures tab). Sémhur (talk) 20:00, 29 January 2016 (UTC)

Sémhur: yes the White Creek and Holte Creek cones were in the Catalogue of Canadian volcanoes but it appears that the website is no longer available. Statemaster and the GVP appear to have gotten those names from the Catalogue of Canadian volcanoes. But I can't seem to find any good sources to prove that those two volcano names are used in the scientific field. If volcanologists used them you would think they would be published in papers, books, journals, etc like the rest of them on your AVB map. By the looks of it those cones aren't significant anyway so it's not a big deal. The ages you mention of were not actually for the volcanoes they were just the Holocene and Pleistocene time spans. Which is why I gave you the true ages for Satah Mountain and Nazko Cone. Volcanoguy (talk) 01:21, 30 January 2016 (UTC)

I did not find a good texture for this location so that I can make a satisfactory 3D model, no video. There are a few on World Imagery and on the Copernicus satellite, but the clouds are interposing. What I did is about what can be done faster and easier for the Hodoo Mountains. Asybaris01 (talk) 19:08, 19 November 2021 (UTC)

@Asybaris01: Okay. How about Mount Edziza? Volcanoguy (talk) 19:40, 19 November 2021 (UTC)

I will do in the coming days. Here is sanitary aparheid, I must to have time and disposition, they stress us every day with this covid stupidity Asybaris01 (talk) 19:57, 19 November 2021 (UTC)
