Volcanic pipe was a good article, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these are addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. Delisted version: October 17, 2006 |
[edit] Wrong subject
This article seems to be talking about what is most commonly referred to as volcanic necks or volcanic plugs. Volcanic pipe usually refers to the hole that the magma travels through, not the solidified magma inside of it. It is sometimes used to refer to both, however, I think that it is talking about a specific kind of volcanic plug that is likely to have diamonds in it, not volcanic plugs in general. Also, there is already an article about volcanic plugs.-- Kjkolb 10:22, 13 January 2006 (UTC)
- There may indeed be other senses of the term, as you indicate, but there are two references that describe a volcanic pipe as the formation extending from the magma dike to the surface in the manner described in this article. Also, the content of this article seems to agree with that listed at diatreme. - Bantman 18:00, 13 January 2006 (UTC)
- Hi, Bantman. :-) I don't dispute that the terms are used interchangeably sometimes (volcanic pipe = volcanic neck = lava neck = volcanic plug). For example, the USGS page uses them interchangeably. However, volcanic pipe also refers to the passage the magma travels through and not just the magma that later solidifies into rock. Also, not all volcanic pipes or volcanic necks are as described in the article. There's an article here that describes volcanic pipes. As for the diatreme article, it does not say that volcanic pipes are all formed that way and it would be wrong if it did. -- Kjkolb 19:17, 13 January 2006 (UTC)
- I'm the first to admit that this article has a lot of expansion potential; I started it while working on diamond and related articles (as you correctly deduced) and frankly just ran out of steam on this one. Anything you could add, even empty headers indicating what information is missing, would be welcome! As for other types of formations that are also sometimes called volcanic pipes, it seems best to pick one term for them and write separate articles, with an {{otheruses}} tag and disambiguation page to direct users. If they are distinct formations, it seems to make more sense to give them separate articles, don't you think? - Bantman 19:37, 13 January 2006 (UTC)
- Hello! To my knowledge the term "volcanic pipe" is mostly synonymous to "diatreme". Therefore the general description of volcanic pipes, necks, plugs, etc. should be put into one single article, with several redirects leading to it, just pointing out the economic importance of some types. The diamond-miners in Southafrica refer to the kind of deposit, described in this article, rather colloquially, as pipes or blows, without the "volcanic". Maybe the informations about Kimberlite pipes and Lamproite pipes are better kept in the seperate articles about Kimberlite and Lamproite? Geoz 12:50, 9 September 2006 (UTC)

[edit] Delisted GA
First off, there are no inline citations, and assuming the first reference is primarily concerned about diamonds, even if the rest of the article gets everything from the second references, that's a rather limited pool to draw material from. Which brings me to my next point, Volcanic pipes have got to have more information on them than this. How about mentioning more than just one diamond mine near these pipes, surely there are at least several notable ones. What about standard temperatures, do these types of volcanoes have different temperatures than most volcanoes, or how about pressure since those sorts of things contribute to diamond formation? There's gotta be more to this topic. Homestarmy 02:34, 17 October 2006 (UTC)
[edit] Supersonic
Not all volcanic pipes are supersomic, in fact very few of them are. a distinction should be made between diamond bearing volcanic pipes and garden variety volcanic pipes. —Preceding unsigned comment added by Russjass (talk • contribs) 16:13, 18 May 2008 (UTC)
