Blairmorite[edit]

Hello Volcanoguy. I don't have an image of blairmorite, but I know someone who does. I'll contact him and ask if he would contribute it. Georgialh (talk) 01:54, 2 October 2014 (UTC)

@Georgialh: thanks. Are you aware of information regarding the source/origin of volcanism that created the Crowsnest Formation? Volcanoguy 02:14, 2 October 2014 (UTC)

Reply[edit]

I haven't been able to find much in the literature about the petrogenesis of the Crowsnest Volcanics (CNV), which really surprises me, given that the mineralogy is so unusual and volcanic rocks are so rare in Alberta. The Bowerman article[1] was the one of the best ones that I found.

I was one of the co-authors on a short article re the CNV for CSPG Reservoir (I don't know if it's appeared yet; I've been in the field all summer and have been pretty much out of touch). Here's an excerpt:

The Crowsnest Volcanics were laid down in a series of eruptions during Albian time. Radiometric dates range from about 93 to 101 Ma[2]. Goble et al. (1999)[3] concluded that alkaline intrusive rocks at Commerce Peak to the south near the Flathead River may have been associated with the Crowsnest eruptions, and Amajor (1985)[4] concluded that the Crowsnest eruptions and/or vents close to them were probably the source of bentonites in the Viking Formation (subsequent radiometric dating shows a compatible date of 100 Ma for these regional marker beds). Palinspastic reconstructions indicate that the eruptions probably occurred in what is now the Cranbrook area. It's estimated that the volcanics originally covered an area of about 1800 km2 and their volume exceeded 209 km3. By comparison the damage area of the 1980 Mount St Helens blast was 600 km2.

I'd like to get down to check out the Commerce Mountain outcrops some time, but it's a bit remote with access via sometimes-active logging roads. Maybe next spring.Georgialh (talk) 03:53, 7 October 2014 (UTC)

@Georgialh: by the way, I have created an article for blairmorite. I am not sure if you are aware but I also started the Northern Alberta kimberlite province, Birch Mountains kimberlite field, Buffalo Head Hills kimberlite field and Mountain Lake cluster articles. Lately I have been working on British Columbia's Itcha Range. Volcanoguy 05:15, 7 October 2014 (UTC)
@Georgialh: it is also worthy to note I could not find much information about the origin(s) of the Northern Alberta kimberlites either. Perhaps volcanic rocks in Alberta have not been studied much because of their rarity? Volcanoguy 10:24, 8 October 2014 (UTC)
Yes, Alberta is indeed impoverished when it comes to volcanics. There's the CNV, the kimberlites, and maybe we can count the Purcell Sill. Other than that, there are beds of volcanic ash ranging in age from Early Cretaceous to Quaternary (e.g., the Mazama ash), but that's about it. You would think that the rarity would inspire Alberta's geology students to be fighting for the privilege of working on them, but I suspect that there's no funding for such things.
As for blairmorite, I'm told that igneous rocks are supposed to be named for their minerals rather than for places, so blairmorite should properly be called analcimite. I haven't checked into that, though. And when asking around about the CNV I triggered a small dispute as to whether there are any actual "trachytic flows" in the CNV, or whether it's all pyroclastics. The question remains unresolved.
I'll see what I can dig up on the Alberta kimberlites. Georgialh (talk) 03:06, 9 October 2014 (UTC)
@Georgialh: Re the ash beds: there are articles for the Mazama Ash and Bridge River Ash. The Winagami sill complex also has an article.
I remember reading igneous rocks are supposed to be named for their minerals but is that an official policy? Are there any disputes over that policy? The name blairmorite for an analcime-rich volcanic rock goes back to the early 1900s. Also, kimberlite is named after the town of Kimberley in South Africa. Volcanoguy 05:39, 9 October 2014 (UTC)
Now that I think about it, that can't be an official policy. There are too many igneous rock names to use mineralogy alone. Johannsen (1933) lists more than 1,200 names.[5] I'll put his definition of blairmorite up on the blairmorite page. He says it was named by someone named Knight, and to see Johannsen vol IV, p. 256-260 for a full description, but I only have a partial photocopy of his Appendix III: Definitions of Rocks. I'll try to get to the Univ library one of these days and look it up.
Most igneous rocks have been named for places where they occur, like syenite (Syene, Egypt). Charnockite is named for the tomb of Job Charnock. So blairmorite should be legit, even though someone did take me to task for using it a while ago. Georgialh (talk) 03:28, 10 October 2014 (UTC)
@Georgialh: another problem naming igneous rocks for their minerals is that most igneous rocks do not have their own unique minerals. Volcanoguy 05:53, 12 October 2014 (UTC)

Hydrothermal vents[edit]

Hey Volcanoguy. The reason for removing the "parenthesis" was purely out of simplification and I did not feel that this was an issue. Adding parenthesis is an act of noting the subtle differences on disambiguation pages or qualifying articles based on existing and/or competitive subdivisions. Removing the parenthesis from the article does not make it less a common name, whereas the short format Magic Mountain or Lost City does show ambiguousness: the name change just removes the ambiguity created by the Wikipedia markup. As much as it is common to use parenthesis to qualify on disambiguation pages, it is not necessarily needed on article pages. The original article already used "Hydrothermal Vent" in its title, I just removed extraneous text. Any search for "Magic Mountain" would have returned a disambiguation page showing the obvious links, and any search for Magic Mountain Hydrothermal Vent, would go directly there without the parenthesis. If you feel that it is overstepping, I invite you to revert, I will not insist (I'm not a purest). Thanks. ruben jc ZEORYMER (talk) 14:48, 29 December 2014 (UTC)

@Zeorymer: there is a difference between "Magic Mountain" and "Magic Mountain Hydrothermal Field". What I am trying to say is that it is more commonly referred to as just "Magic Mountain", not "Magic Mountain Hydrothermal Field". "Magic Mountain" is a disambiguation page and the Magic Mountain field is not the WP:PRIMARYTOPIC so that is why "(hydrothermal field)" was added in the title. Volcanoguy 15:03, 29 December 2014 (UTC)
Your right in addressing that there is a difference between "Magic Mountain" and "Magic Mountain Hydrothermal Field", but not in the way you stated. Regardless, as I stated, this is not an issue. As they say "be bold". I invite you to revert those changes. ruben jc ZEORYMER (talk) 15:31, 29 December 2014 (UTC)

Scientific notation[edit]

Hi, you left a plea for help at the Math Wikiproject page which should have been directed to the Wikipedia:Reference desk/Mathematics since it didn't really involve the math articles. But to answer your question - you are dealing with Scientific notation, very common in the physical sciences and engineering. For your specific example, ~10-4 km3yr-1, the twiddle (~) means approximately, 10-4 = 0.0001 (see the article), and km3yr-1 gives the units which in this case are cubic kilometers per year (it is a rate of flow, so expressed as a volume per some time period). I haven't seen the -1 exponent used in a units expression very often, but that is a stylistic convention. I would have expected to see it written as km3/yr. I hope this helps. Bill Cherowitzo (talk) 04:21, 10 January 2015 (UTC)

@Wcherowi: I'm just a bit puzzled since I am not used to seeing things like that. You can find the paragraph I quoted here on pages 1284 and 1285. It says "the eruption rate increased markedly (e.g., ~10–4 km3 yr–1) when volcanism began at Level Mountain at 15 Ma." Okay. After that it states "when Mount Edziza began to erupt (ca. 7 Ma), rates of magmatism for the northern Cordilleran volcanic province increased to ~3 × 10–4 km3 yr–1." I'm guessing this is a greater measurement since they say the magmatism rate increased. But how much of a difference is that to ~10–4 km3 yr–1? Then after that it says the "rates of magmatism have remained relatively constant at 10–4 km3 yr–1", which is similar to what is given for when volcanism began at Level Mountain. I say similar because they don't give the twiddle (~) for that rate. Then it says "current rates of magmatism for the northern Cordilleran volcanic province are much less than those estimated for Hawaii (10–1–10–3 km3 yr–1; Shaw, 1987) or the Cascade volcanic arc (0.2–6 km3 yr–1; Sherrod and Smith, 1990)." How much of a difference are the Hawaii and Cascade Arc magmatism rates to the Northern Cordilleran Volcanic Province rates of 10–4 km3 yr–1 and ~3 × 10–4 km3 yr–1? Volcanoguy 05:28, 10 January 2015 (UTC)

After Edziza erupted the flow rate increased to 0.0003 km3/yr (300% of what it was before). The Hawaii estimate is given as a range from 0.1 to 0.001 km3/yr (are you sure you copied that correctly? Ranges are usually given from smaller to larger values, and this isn't) and the Cascade arc ranges from 0.2 to 6.0 km3/yr. The Hawaii values range from 1000 to 10 times those of Cordilleran, while the Cascade values are 2000 to 60,000 times as large. All these values are approximate estimates, so I wouldn't put much store in the fact that some of them are reported without the twiddle. Bill Cherowitzo (talk) 18:35, 10 January 2015 (UTC)

@Wcherowi: sorry for the long response time; I have been busy collecting information to rewrite the Level Mountain article. Yes the Hawaiian values were copied correctly, don't know why the range is given from larger to smaller values. Volcanoguy 08:53, 16 February 2015 (UTC)

Category:Mountains under 1000 metres[edit]

Hi Volcanoguy, I see you reverted again my attempt to clarify this category (which I created a while back) with a lower limit. So where do you see the lower height limit for a mountain? 900 m? 500 m? 300 m? 100 m? 10 m? 1 m? Clearly the lower we set it the more 'bumps' get included. But IMHO we should try and base it on some standard in the English-speaking world. The US doesn't have one, Britain and Ireland do. I'm not sure about Canada, Australia or South Africa, etc. Alternatively, if we can't agree where the limit is, confusion will reign and we may as well delete it. Thoughts? --Bermicourt (talk) 07:37, 13 July 2015 (UTC)

That is the point there is no universally accepted definition of a mountain. The UK and Ireland may have a definition for what a mountain is in their country but that definition is not the same worldwide. So you have landforms below 600 metres outside of Ireland and the UK called mountains as well. I don't know what the problem is to just include landforms that are called mountains. I am keeping a WP:NPOV view here as the category should be used fairly without bias. Volcanoguy 08:20, 13 July 2015 (UTC)
The point which the text acknowledged clearly. And since there is no universal definition, there can be no such thing as a NPOV - wherever we decide the lower cutoff is will be our POV. In my case, I have based it on the only official definition I can find, backed up by a Dictionary of Geography source; you've just fixed it at 1 m, since no cutoff means anything counts. So several hills were included in the category that even failed the old US definition of a mountain being 1,000 feet and others were part of "Foo Hills" , so clearly not considered mountains either. There's not much point having a category if people can't see what's "in" and what's "out" of it. --Bermicourt (talk) 20:36, 13 July 2015 (UTC)
@Bermicourt: I am still in disagreement with you. If a geographic feature is known as a mountain it's a mountain, simple as that. As a result such things belong in mountain categories, including Category:Mountains under 1000 metres. You are defining what a mountain is based on an Ireland/UK definition, which is a bit on the POV side since you are not representing a worldwide view on the issue. If there is no universal definition for something you are not supposed to use a definition that is only for two countries in Europe. To tell you the truth there are geographic features called hills that have elevations greater than 600 metres as well. What are you going to do there? Volcanoguy 14:21, 15 July 2015 (UTC)
If a mountain is known "by whom" as a mountain? Is the Teckberg a mountain? The Täfelberg? The Wilseder Berg? And having listened to your argument, I've moved on from using the UK/Irish definition guideline universally and changed the guideline to absolutely reflect a worldwide view - inviting other editors to suggest refinements. Of course, you will always get the occasional hill called "Foo Mountain" and occasional mountain called "Foo Hill" but then a Bombay Duck is not a duck... --Bermicourt (talk) 14:37, 15 July 2015 (UTC)
Sorry I should have said that I also replied to your comments on the talk page of the category - you may not have seen my latest form of words which are genuinely trying to be inclusive of different national perspectives. Bermicourt (talk) 14:41, 15 July 2015 (UTC)

Does Edziza eruption caused 536 AD cooling?[edit]

Hi Volcanoguy. I just want to ask that it is possible that Edziza volcanic complex may related to tephras QUE-1859 in Greenland ice-core? "Timing and climate forcing of volcanic eruptions for the past 2,500 years" noted that chemical of tephras in depths of 327 m (536 AD) similar to those of volcanoes in Cordilleran Volcanic province (Edziza).

It is possible that Edziza volcano eruption caused the large Northern Hemisphere cooling in 536 AD? — Preceding unsigned comment added by Siyu Lai (talkcontribs) 02:28, 10 October 2015 (UTC)

@Siyu Lai: It is a possibility but there are other large volcanoes in the Northern Cordilleran Volcanic Province that have received very few studies (e.g. Heart Peaks and Level Mountain) so they could be potential sources as well. Volcanoguy 06:17, 10 October 2015 (UTC)
@Siyu Lai: If you have information about the Greenland ice-core being potentially linked to the Northern Cordilleran Volcanic Province please include it in the article. Thanks. Volcanoguy 19:46, 10 October 2015 (UTC)

I have some information about the lake-core from northern British Columbia that linked to Northern Cordilleran Volcanic Province. "Holocene tephras in lake cores from northern British Columbia, Canada" — Preceding unsigned comment added by Siyu Lai (talkcontribs) 00:27, 11 October 2015 (UTC)

@Siyu Lai: I created Finlay tephras five years ago if you want to improve it. Volcanoguy 01:30, 11 October 2015 (UTC)

Region_code editing with AWB[edit]

Thank you so much for stepping in and finishing the task! I can only do about 300 at a sitting, and then my eyes go cross. (Perhaps you did a smarter thing -- you're only doing the replacement, while I turned on genfixes).

Looks like we'll be done very soon! Congratulations!

I'll soon be taking a wikibreak for the end of the year, so in case you finish and I'm not around:

  1. User:Hike395/MtnComboBox should be ready to go.
  2. Copy User:Hike395/MtnComboBox to Template:Infobox mountain/sandbox and check out Template:Infobox mountain/testcases for any errors
  3. Copy User:Hike395/MtnComboBox to Template:Infobox mountain range/sandbox and check out Template:Infobox mountain range/testcases
  4. If everything looks ok, replace the contents of Template:Infobox mountain up until the <noinclude> with User:Hike395/MtnComboBox. This requires template-editor rights or higher -- if you don't have that, glue the <noinclude> stuff after the MtnComboBox code, and do an edit request at Template talk:Infobox mountain
  5. Then, turn Template:Infobox mountain range into a redirect to Template:Infobox mountain
  6. Done, drink a Molson! :-)

Thanks again for finishing this! —hike395 (talk) 02:41, 7 December 2015 (UTC)

@Hike395: No problem. I copy and pasted MtnComboBox to both mountain and mountain range sandboxes but I am having trouble replacing the contents of Template:Infobox mountain. Volcanoguy 03:05, 7 December 2015 (UTC)
I think that's because you're not a template-editor. But I am! Let me do steps 4 and 5, and then we'll be done and we can both have a Molson!! —hike395 (talk) 03:35, 7 December 2015 (UTC)
Yes check.svg Done Woo hoo! Let me know if you see any problems. —hike395 (talk) 03:55, 7 December 2015 (UTC)
@Hike395: I updated Level Mountain this month if you need an example of a massif. Volcanoguy 05:09, 7 December 2015 (UTC)

Anahim Volcanic Belt[edit]

Hello Volcanoguy, see my answer and question here. Sémhur 19:49, 24 January 2016 (UTC)

My apologies[edit]

For my mistake on the Nazko earthquake article. I got mixed up and marked the wrong reference. If you take a look at reference number seven here 2007–2008 Nazko earthquakes#References it goes to this 404 message. So I don't mess thing up any further could you take a look and see if you can fix it or at least apply a "dead link" tag. Thanks for your time. MarnetteD|Talk 20:11, 18 April 2016 (UTC)

@MarnetteD: I added the "dead link" tag to the proper reference as I don't have time to try and fix it right now. Volcanoguy 20:13, 19 April 2016 (UTC)
Thanks V. MarnetteD|Talk 23:15, 19 April 2016 (UTC)

Warden Peak and other Vancouver island volcanos[edit]

Back in 2008, you created the article Warden Peak as well as other articles of Vancouver island mountains. An IP just removed statements that the peak (as well as other Vancouver Island mountains) was a volcanic plug. I checked the reference and did not see any mention of volcanic origin. Just an FYI. Cheers Jim1138 (talk) 06:47, 25 May 2016 (UTC)

@Jim1138: I just reverted the IP's edits to Haddington Island and Twin Peaks. As far as I am aware of their claim that there are no volcanoes on Vancouver Island is false. According to reliable sources Twin Peaks and Haddington Island are part of the Alert Bay Volcanic Belt, which formed as a result of volcanism along the Cascadia subduction zone.

Mountains and volcanoes in Canada[edit]

Hi Volcanoguy, I know this is very much your specialist area, so whilst I made comments earlier (forgot to log in so it was just a pair of IP edits) on the garibaldi range talk page, perhaps I should clarify it and ask you, whether anything needs doing, or if I've just got the wrong end of the stick :) I saw a video of a landslide on Mount Currie that someone said was actually associated with the 'pemberton caldera' which attracted my attention as I wanted to debunk their assertion that this might be an upcoming mass wastage eruption trigger. So a quick wikipedia search led me to the following articles

Mount Currie (British Columbia), Pemberton Volcanic Belt, Garibaldi Volcanic Belt, Coast Mountains, Garibaldi Ranges,Pacific Ranges and a few hot spring articles including Boulder Creek (Lillooet River) which seems likely connected to the same Pemberton volcanic belt

Now the Mount Currie article says it is the northernmost of the Garibaldi range, but that article doesn't mention Mount Currie, nor does the Garibaldi ranges article mention the Garibaldi Volcanic Belt - which seems like an ommission - but perhaps they just have similar names and are adjacent I've misunderstood? A few of the other articles look like they could have blue links added that point to the volcanic article. I'm tempted to just start on that but I don't want to accidentally step on your toes there at all EdwardLane (talk) 21:50, 5 September 2016 (UTC)

@EdwardLane: Hi. I'm not really understanding what you're trying to tell me. All the articles you linked are for different features. The Garibaldi Ranges and the Garibaldi Volcanic Belt have similar names but they're both different geologically. There are some volcanoes in the Garibaldi Ranges that are part of the Garibaldi Volcanic Belt (e.g. Mount Garibaldi, Mount Price, The Black Tusk) but the Garibaldi Ranges are mostly made of older uplifted non-volcanic rocks. This also goes for the Pacific Ranges and Coast Mountains. It's the same thing with the Andes and the Andean Volcanic Belt; a geological feature overlapping with a geographical feature.
As far as I know Mount Currie is not volcanic and I have never heard of the "pemberton caldera", nor do I know of a caldera near Pemberton. The Garibaldi and Pemberton belts are two different but related features, although their northern limits overlap each other. The Boulder Creek article clearly states the hot springs are related to volcanism of the Mount Meager massif, which is part of the Garibaldi Volcanic Belt. I hope I cleared some things up for you. See the Canadian Cascade Arc article for more. Volcanoguy 03:11, 6 September 2016 (UTC)


Thanks - that clarified the picture in my head somewhat - I feel the garibaldi range article (along with most articles about mountains) could probably do with a paragraph saying something much like this block quote from the cascade volcanoes article)

Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper.

Which serves to link the geography to the underlying geology - perhaps (in this case) something along the lines of 'the Garibaldi Ranges, and the overlapping Garibaldi Volcanic Belt both take their names from the volcano Mount Garibaldi, but the Garibaldi Ranges are mostly made of older uplifted non-volcanic rocks, ...... and then I don't know enough to finish that paragraph - are all the volcanics from the volcanic belt inside the geographically described garibaldi range, presumably the belt is caused by back arc volcanism so they mostly run parallel and to the east of the subducted/uplifted rocks? - or do they extend outside that area? hope that makes sense - I get mightily confused when trying to look at a mountain and finding that there is no detail about the geology, unless I hunt around a bunch of other articles nearby. EdwardLane (talk) 13:30, 16 September 2016 (UTC)
@EdwardLane: No, the Garibaldi Volcanic Belt has a greater extent than the Garibaldi Ranges. Compare File:Vancouver Island-relief GaribaldiRanges.png red outline with File:Garibaldi Volcanic Belt-en.svg. You will see the "Mount Garibaldi area" is the only portion of the Garibaldi Volcanic Belt inside the geographical boundaries of the Garibaldi Ranges. The Garibaldi Belt itself is a volcanic arc; back-arc volcanism is represented by the Chilcotin Group. Volcanoguy 16:10, 16 September 2016 (UTC)

Dike swarm[edit]

Hi! You created this article years ago, and I wanted to confirm that a correction I just made is right. I think when you wrote "Madalena Radial Dike Swarm (southeastern Wyoming)", you really meant "Magdalena radial dike swarm (central New Mexico)". "Madalena" really puzzled me for a while, as there seemed to be nothing I could find with that name in Wyoming. Could you confirm that the Magdalena dike swarm was really the one you meant? Thanks for checking. — Gorthian (talk) 21:38, 6 September 2016 (UTC)

@Gorthian: Hi. To be honest I can't remember. When I created the dike swarm article I just did a quick Google search for "dike swarm" and "dyke swarm" then added the ones I found in the examples section. Volcanoguy 00:31, 7 September 2016 (UTC)
Okay, that's fair. I think my correction (also based on a Google search) can stand, then. Thanks! — Gorthian (talk) 00:41, 7 September 2016 (UTC)

New 10,000 Challenge for Canada[edit]

Hi, Wikipedia:WikiProject Canada/The 10,000 Challenge is up and running based on Wikipedia:The 10,000 Challenge for the UK which has currently produced over 2300 article improvements and creations. If you'd like to see large scale quality improvements happening for Canada like The Africa Destubathon, which has produced over 1600 articles in 5 weeks, sign up on the page. The idea will be an ongoing national editathon/challenge for Canada but fuelled by a contest such as The North America Destubathon to really get articles on every province and subject mass improved. I would like some support from Canadian wikipedians here to get the Challenge off to a start with some articles to make doing a Destubathon worthwhile!
