[edit] What is being said?
Basalt is an extrusive igneous rock -- this means that Basalt is one member of a class of objects. What distinguishes basalt from the other members of this class? Are no other rocks extrusive and igneous? I have no idea what is being said, and I am not in high school, I am merely a high school science teacher.

[edit] Basalt
Basalt is an extrusive igneous rock, sometimes porphyritic, and is often both fine-grained and dense. Basalt in the tops of subaerial lava flows and cinders will often be highly vesiculated, imparting a lightweight "frothy" texture to the rock. The term basalt is often casually applied to shallow intrusive rocks with a composition typical of basalt, but rocks of this composition with a phaneritic groundmass should generally be referred to as gabbro. The crustal portions of oceanic tectonic plates are predominantly made of basalt. Frankly, I do not get a word of what it means. Thankfully I know what Basalt is.
There you go. Hopefully even oompa loompas can read it and know what it is now.Rolinator 09:12, 22 January 2006 (UTC)
Basalt (IPA: /ˈbæsɒlt, bəˈsɒlt/) is a common gray to black extrusive volcanic rock. It is usually fine-grained due to rapid cooling of lava on the Earth's surface. Basalt isn't extrusive. The word "Basalt" is based on the chemial composition and grainsize, not if it was formed on the surface or underground. It isn't usually fine-grained, by defintion it is fine-grained. If it was medium/coarse grained it would be a dolerite/gabbro.
[edit] Recent changes
This page has improved a lot in the last week. Looks good now.Rolinator 07:47, 3 November 2006 (UTC)
[edit] Small usage fix
Changed "comprised predominantly of basalt" to "composed predominantly of basalt." A thing is not comprised of its parts; a thing comprises its parts. 140.147.160.78 21:30, 28 March 2007 (UTC)Stephen Kosciesza
- Thanks for taking the time to justify your changes, it is appreciated by those of us who watchlist these articles. The Merriam-Webster Online Dictionary entry for "comprise" has a useful note on usage. Based on the note, it would appear that "comprised" is commonly used in this sense, although likely to be criticized as wrong by many (like you). I'm OK with using "comprise" that way, I see it all the time in scientific papers, but I'm happy to accept "composed" as more correct usage.
- By the way, you've been making many small but useful conrtributions to Wikipedia over the past months, might I recommend signing up for an acount? See WP:ACCOUNT for info on the numerous benefits of having an account. No pressure, it's up to you. Thanks. --Seattle Skier (talk) 23:01, 28 March 2007 (UTC)
[edit] Extremely confusing
I'm trying to do a project on basalt and I hardly know what's being said. Some of us are still in high school, you know. BlackSlivers 00:08, 20 June 2007 (UTC)
The following sentence seems awkard to me: Pliny used the word basalt and it is said to have had an Ethiopian origin, meaning a black stone. Even though Pliny has a link, the author uses the name as if anyone reading this article is sure to know who Pliny is and why he was important. I feel it should have had some kind of comment appended to it such as: Pliny, the world's oldest rock hound in the 1920's,................. I humbly submint this comment for peer review and suggest it only in the hope that it will make the article more easliy readabale. No malice was intended.69.1.59.67 04:53, 21 September 2007 (UTC)ID 2007-09-21
[edit] What about it's uses?
Don't get me wrong, I like to read about how the stone is formed. But I guess I feel like this article overlooks the practical uses of basalt as tile. I'd fix it myself, but I'm horrible at gathering information in an easy to read way. But it'd be nice to have a section about the various uses of basalt, as well as it's weaknesses/strengths as a material. —Preceding unsigned comment added by 71.228.228.6 (talk) 03:37, 18 September 2007 (UTC)
Whats it used for? found on mars? who cares.. —Preceding unsigned comment added by 64.81.64.64 (talk) 03:06, 19 September 2007 (UTC)
[edit] Basalts' Uses
I also agree with the previous comment about the fact that the artical needs a section about the rocks' uses. I'm currently doing a project on Rocks for school & I've chosen Basalt as one of my subjects. I have been asked to find out about its formation, uses & where its found. However, I cant complete the 'uses' section because of this. I have tried looking for it over the internet & Im sure that it will take me ages to do! So please could you include a uses section in the future - thanks. - Mrsir2 —Preceding unsigned comment added by 81.105.71.77 (talk) 14:29, 6 October 2007 (UTC)
[edit] Traprock
"Traprock" forwards to this article. Could someone add (in the article) why? Thanks, Ibn Battuta (talk) 21:37, 9 December 2007 (UTC)
