Expansion

[edit]

This article needs big time expansion. The NCVP is the most active volcanic area in Canada and has been an area of active volcanism for at least 20 million years, making it the oldest active volcanic zone in Western/Northern Canada. Recently, I deleted a paragraph on the East African Rift article that stated the East African Rift is the only example of actively rifting continental crust besides the Baikal Rift Zone in eastern Russia and the West Antarctic Rift in Antarctica, which is a crock of shit. The NCVP rift is still active and its larger than the Baikal Rift Zone. The user that created the article likely did not know much about continental rifts and the claim was unreferenced, giving a hint it is not true. Anyway, I will do a massive edit on the NCVP article later when I have enough information since other editors associated with WP Canada and WP Volcanoes do not support Canadian volcanism articles - the majority of WP Volcanoes is the expansion of active/famous volcanoes while WP Canada mostly focuses on human-related articles. Black Tusk (talk) 03:42, 30 June 2009 (UTC)[reply]

Well now that I have expanded and rewritten this article majorly, it is probably time to get this article to GA or FA. BT (talk) 00:29, 10 November 2009 (UTC)[reply]
I have to agree with Black Tusk that WP:VOLCANO is about as un-supportive as they come :( Tis' a shame. ResMar 19:55, 21 November 2009 (UTC)[reply]
It's also a put down because lots of volcanoes in Canada receive little public attention in general and their existence is not widely known. With nobody not even working on Wikipedia articles about Canadian volcanoes and related topics, it does not make them more noticable. But thankfully I am one of the few that recieves public attention to them. Hey, the Geological Survey of Canada even thanked me when they noticed the hard work I put into some Canadian volcano articles. BT (talk) 21:29, 21 November 2009 (UTC)[reply]
Another fact is if you put faith into Canadian volcanology you will likely get more interested in the subject.....I remember when I first found out there are volcanoes in Canada I was quite surprized like typical Canadians when they here about volcanic activity in Canada but then I found out most of the recent volcanic activity goes back a few thousand years ago so I became not as interested in them for a while because at the time I was more interested in frequently active volcanoes like what most of the other members of WP Volcanoes focus on. But no I did not quit my research, I kept on doing research to learn more about their eruptive history, volcanic hazards etc and my interest eventually rose again. Another thing I learnt was the fact that a few thousand years ago is not old in volcanological terms. Insted, it is rather recent. BT (talk) 22:27, 21 November 2009 (UTC)[reply]
Well I suppose it's partially because people without interest in the subject have little text resource to go on. Then theres you. xD ResMar 19:34, 22 November 2009 (UTC)[reply]

Hudson Bay impact

[edit]

North Cordilleran Volcanic Province might have been formed 13,000 years ago when an extraterristrial rock fell to the Hudson Bay. The impact was so devastating, it buried the albertasaurus, and slid the north america westward. Ever since the impact, the North American Volcanic Province is now rifting, at an inch per year. == —Preceding unsigned comment added by Arviatlands (talk • contribs) 20:36, 5 January 2010 (UTC)[reply]

It is clear the Northern Cordilleran Volcanic Province did not form from an impact event. The province related to plate tectonics. Plus, there are rocks related to the Northern Cordilleran Volcanic Province older than 13,000 years. I highly doubt what you said is even citable. I also see you created a similar note on Talk:Interior Plains. You make it sound as if some large metorite impacted a large part of North America. So stop adding nonsense on talk pages..... BT (talk) 01:15, 7 January 2010 (UTC)[reply]

Review

[edit]

Black Tusk asked me to review the article, so that'l go here. I also made a few minor grammatical corretions and whatnot.

General

I don't understand what you are stating here; I barely understand any guidelines and stuff like that LOL. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
WP:ALT. You have to use the |ALT= parameter within the image to provide a discription for quote "visually-impaired." It took me forever to figure out what it meant. To save you the trouble, don't read the guideline, it's mad unclear, just describe the image itself (not what's in it, that's the caption's job) and run with it. I gave an image for an example. :)
Alright I think I understand now. Are the captions alright? BT (talk) 00:25, 25 November 2009 (UTC)[reply]
Hehe, not descriptive enough. Check Loihi Seamount to figure out what I mean. ResMar 05:06, 25 November 2009 (UTC)[reply]
Ok, you were struggling with it, so I did it for you :) ResMar 16:17, 26 November 2009 (UTC)[reply]
Alright, thanks. I'm not very good with alts. BT (talk) 19:46, 26 November 2009 (UTC)[reply]
  • The article is way over-referenced. You have three of the same ref dispersed amongst a single paragraph, for example.
The more referenced the article is, the less likely of someone questioning weather it is something true or not. In some cases, someone will add a citation needed template. The introduction is the least referenced section in the entire article. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
Well all right...ResMar 01:04, 23 November 2009 (UTC)[reply]

Lead

  • containing a number of volcanoes and volcanics Volcanics is a vauge term, better to say volcanoes, calderas...etc., or to say "volcanics such as..."
Deleted "volcanics" because it is not needed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • The province has formed due to extensional cracking of the North American continent similar to other extensional continental volcanic provinces... I personally know what an "extensional continental volcanic providence" is, but most laymen don't.
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • At least three large distinctive volcanoes... Lot going on there. I would put a comma after large: at least three large, distinctive volcanoes.
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • Most of these small cones have been sites of only one volcanic eruption in contrast to the larger volcanoes found throughout the province. In contrast to the larger volcanoes, which have averaged how many eruptions?
I think I have fixed this issue. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
  • However, the Northern Cordilleran Volcanic Province... Second time using the full, lengthy name in two sentences; I recommend shortening it to just "province".
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • ...interpreted to be part of a gap in the Pacific Ring of Fire between volcanoes of the Cascade Volcanic Arc further south and volcanoes of the Aleutian Arc further north. Rm volcanoes. It ways so right in the name.
Removed volcanoes because it is redundant. BT (talk) 22:43, 22 November 2009 (UTC)[reply]
  • Until now, the Northern Cordilleran Volcanic Province includes over 100 independent volcanoes that have been active in the past 1.8 million years. Wait, "Until now"? The sentance is fine but that snippet at the begggining makes no sense.
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • At least three of them have erupted historically... I know what you mean by "historically" but it's a vuge term. Try "within recorded history".
All three eruptions occurred in the past 360 years so I replaced "historically" with "in the past 360 years". BT (talk) 22:38, 22 November 2009 (UTC)[reply]
Even better. ResMar 01:04, 23 November 2009 (UTC)[reply]

Origins and chemistry

  • The Northern Cordilleran Volcanic Province has existed for at least 20 million years... Hehe, Black Tusk, that sounds like the dinosaurs came up with the technical term for the area. "The features in the Northern Cordilleran..."
Not all of the features have existed for 20 million years..... BT (talk) 22:29, 22 November 2009 (UTC)[reply]
No, I mean that the NCVP is a human-invented term. But the features in it are not. So it sounds like the Dinosours thought up the term. ResMar 01:04, 23 November 2009 (UTC)[reply]
LOL ok I understand now. Rewordered that sentence. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
  • ...along short northerly trending en-achelon segments... Whats "en-achelon" oO?
Deleted. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
No such article exists and a link for deglaciation is nonsense. It's like linking erosion, glaciation or some other common process. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
'Kay. ResMar 01:04, 23 November 2009 (UTC)[reply]
  • ...although continental rifting is the most accurrate mechanism for Northern Cordilleran Volcanic Province volcanism. Isn't it the most accurate mechanism describing the providence? (same sentance as the above comment)
Eh? ResMar 23:01, 24 November 2009 (UTC)[reply]
Yes it is. I will add the missing "terminology". BT (talk) 00:30, 25 November 2009 (UTC)[reply]
  • Further evidence for this mechanism is magmas of the Northern Cordilleran Volcanic Province are mainly alkaline... Now this is just a rambing sentance. Can you break it up? I would reccomend a list...
Reworded. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • A range of more heavily alkaline rock types unusually found in the Western Cordillera are regionally widespread in the Northern Cordilleran Volcanic Province. Unusually is placed akwardly. How about "A range of unusually alkaline rock types found in..."
Replaced "unusually" with "not commonly". BT (talk) 22:40, 22 November 2009 (UTC)[reply]
  • The most magnesium oxide-rich nephelinites, basanites and alkaline basalts all through the Northern Cordilleran Volcanic Province display trace element abundances and isotopic compositions that are logical with an asthenospheric source like those for average oceanic island basalt and for alkaline basalts younger than five million years in the rift-related Basin and Range Province of southwestern United States and northwestern Mexico. Wow, advanced grammer oO Is there a link for asthenospheric?
Linked. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • One hypothesized explanation for oceanic island basalt in the Earth's upper mantle under the Northern Cordilleran Volcanic Province is the existence of a slab window. Wikilink slab window.
Slab window is already linked before that sentense. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
Where? Is it in the same section? Res Mar 01:04, 23 November 2009 (UTC)[reply]
Yup: Other mechanisms suggested for triggering volcanism in the Northern Cordilleran Volcanic Province include mantle plumes, deglaciation and slab windows, although continental rifting is the most accurrate mechanism for Northern Cordilleran Volcanic Province volcanism. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
Ok. ResMar 23:01, 24 November 2009 (UTC)[reply]
  • Alkaline basalt, lesser hawaiite and basanite magmas from effusive eruptions create the massive shield volcanoes and small cinder cones, several of which comprise lherzolite magma. The massive shield volcanies and small cinder cones of what?
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]

Terranes and boundaries

  • The basement of... Basement? Base rock? Remember to stick to terms that anyone can understand.
Changed to bedrock. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • The Yukon-Tanana and Cassiar terranes consist of shifted sedimentary and metamorphic rocks that did not originate on the North American continent. Wait, then where is it from?
Uh, I think that is a nearly impossible question to answer. Nobody was around millions of years ago to know where they originated from..... BT (talk) 22:29, 22 November 2009 (UTC)[reply]
So they don't know, basically? ResMar 01:04, 23 November 2009 (UTC)[reply]
Yes. Of course it's possible to found out if the rocks did not originate from the continent, but it could be impossible to find where exactly the rocks originated from. For example, the Insular Islands collided with the west coast of North America millions of years ago, but before the collision the islands were out in the ocean somewhere. Also, the sedimentary and metamorphic rocks comprising the Yukon-Tanana and Cassiar terranes most likely collected on North America as tectonic plates collided with the North American Plate so the sedimentary and metamorphic rocks would be moving all the time. Probably better if the sentence was reworded a bit. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
Reworded the sentence as "The Yukon-Tanana and Cassiar terranes consist of shifted sedimentary and metamorphic rocks that were derived from the North American continent." if that makes it more clear. BT (talk) 20:28, 23 November 2009 (UTC)[reply]
All right :) ResMar 23:01, 24 November 2009 (UTC)[reply]

Xenoliths

  • Since it's a section on a not-widely-known geological term, you should tell the readers what a Xenolith is first.
Done. BT (talk) 00:30, 23 November 2009 (UTC)[reply]

Megacrysts

  • Again, define what megacrysts are.
Done. BT (talk) 00:30, 23 November 2009 (UTC)[reply]

Lava tubes

  • At the Level Mountain Range, lava tubes reach diameters of 1 m (3.3 ft) to 2 m (6.6 ft) that owed their origin to highly fluid lavas with temperatures of at least 1,200 °C. This seems like a spliced sentance. It really should be two sentances. That isn't the right word for it.
Splitted sentense. BT (talk) 22:47, 22 November 2009 (UTC)[reply]
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]

Eruptive history

  • Lava fountains can occur in the Northern Cordilleran Volcanic Province roughly every 100 years. Can or do?
The sourse given for lava fountains occuring roughly every 100 years uses can, not do. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
  • The massive Level Mountain Range shield, occupying an area of 1,800 km2 (690 sq mi) and a volume of more than 860 km3 (210 cu mi), is the most voluminous and most persistent volcano of the Northern Cordilleran Volcanic Province. What do you mean by "persistant"? that it erupts more?
No. It was ment to mean long-lived. BT (talk) 22:29, 22 November 2009 (UTC)[reply]
Then shouldn't you say oldest? "Persistant" is open to interpretation. ResMar 01:04, 23 November 2009 (UTC)[reply]
I already replaced "persistent" with "long-lived". BT (talk) 02:07, 23 November 2009 (UTC)[reply]
  • In northern Yukon, similar aged volcanics can be found, including 19.9±0.5 million year old volcanics at Forty Mile and 17.2±0.3 million year old volcanics at Sixty Mile. What is 40 and 60 Mile.
I am not quite sure what Forty Mile and Sisty Mine is not they are most likely the names of communities or places (e.g. Forty Mile, Yukon). BT (talk) 22:29, 22 November 2009 (UTC)[reply]
Hmm, is Forty Mile, Yukon "Fourty Mile"? Then you can redlonk Sixty Mile and it'll be fine. ResMar 01:04, 23 November 2009 (UTC)[reply]
I guess so. Linked Forty and Sixty Mile and both appear as blue links. BT (talk) 02:07, 23 November 2009 (UTC)[reply]
That worked out fine ;) ResMar 23:01, 24 November 2009 (UTC)[reply]
  • Throughout the Pleistocene epoch 1.6 million to 10,000 years ago, volcanism in the Northern Cordilleran Volcanic Province broadly contributed with glacial ice and ice sheets during glacial periods, including the large Cordilleran Ice Sheet. Is "contributed" the right word?
Fixed. BT (talk) 22:29, 22 November 2009 (UTC)[reply]

Actually, in general the back end of the article is very smooth. A few copyedit things here or there but well done. That, or I've been staring at the screen for too long... ResMar 21:38, 22 November 2009 (UTC)[reply]

I think you should overview your points while I am fixing them in the article because I don't quite understand some of them. BT (talk) 22:30, 22 November 2009 (UTC)[reply]
Most things are fixed but there are a few I'm ready to argue with you on (figuratively speaking) :) ResMar 01:05, 23 November 2009 (UTC)[reply]
Ok, just one more (you missed it...?) ResMar 23:03, 24 November 2009 (UTC)[reply]
Ah, one reference still needs to be filled out. I'm not a professional at filling out references so I'm likely not the person to fill it out :-(. BT (talk) 01:43, 25 November 2009 (UTC)[reply]
That's going to be a problem. There's a guy going around, User:Fifelfoo, and he's raising hell :( I never even KNEW there were standards for refs...ResMar 05:06, 25 November 2009 (UTC)[reply]
I added more detail for ref 7 in the hot springs section. BT (talk) 19:36, 26 November 2009 (UTC)[reply]

Not a product of back-arc basin volcanism

[edit]

I delinked "extensional cracking" to the back-arc basin article because volcanism in the Northern Cordilleran Volcanic Province is clearly not related to back-arc basin volcanism. If the Northern Cordilleran Volcanic Province is related to back-arc basin volcanism there would likely be a volcanic arc just west of the volcanic province along the Pacific coast like most portions of the Pacific Ring of Fire, which there isn't. The last active volcanic arc near the Northern Cordilleran Volcanic Province was the Coast Range Arc, which deceased about 30 million years before the formation of the Northern Cordilleran Volcanic Province 20 million years ago. Therefore, I relinked "extensional cracking" in the introduction to the rift article instead. BT (talk) 04:16, 8 December 2009 (UTC)[reply]

And if the Northern Cordilleran Volcanic Province is indeed related to back-arc basin volcanism, scientists would very likely classify volcanism in the province related to back-arc basin volcanism. I also doubt there are references or reports that state the Northern Cordilleran Volcanic Province as a back-arc basin. BT (talk) 04:27, 8 December 2009 (UTC)[reply]
