chert
For those of you who are confused, I present the http://www.m-w.com definition of “chert”, and a large assortment of words I’ve never seen in my life…
Main Entry: chert
Pronunciation: 'ch&rt, 'chat
Function: noun
Etymology: origin unknown
Date: 1679
: a rock resembling flint and consisting essentially of a large amount of fibrous chalcedony with smaller amounts of cryptocrystalline quartz and amorphous silica
- cherty /'ch&r-tE, 'cha-/ adjective

WHAT IS WRONG WITH YOU PEOPLE?!!??
We are not clairvoyant! Cite please! Cite, cite, cite, cite, cite, cite, cite and CITE!!!
Fuck!
Concerning Upham, leave him alone. He’s just a harmless little Upham with a warped sense of humor.
Plus he knows how to cite, too!
GAH!
I need a smoke.
Chert was commonly by prehistoric peoples for their toolmaking (projectile points, knives, etc.). It fractures conchoidally, making it ideal for percussion flaking, hence the widespread usage. The darker variety is what we know as flint.
(Sorry–you pick up a lot of geology when getting a degree in archaeology.)
But what the heck does this have to do with Upham?
Um, the word used is there. You just can’t see it.
I’m not being rough on Upham, believe me.
I had almost said spodumene
Could this be one of those space-wasting threads everyone’s been going on about? I mean, it makes no sense and a lot of people are going to waste a lot of time opening it up looking for some issue (or fightin’ words) between scratch1300 and Upham, and all they’re going to find is this.
(I probably shouldn’t even be responding because I know I’m going to get yelled at, but I cannot control myself.)
Well, saying spodumene wouldn’t be all that hard on Upham, as it’s only about a 6 on the Mohs Hardness Scale, IIRC.
I’m seeing a pattern here… they both have high silicate content… ???
sigh.
Do I have to download another Quicktime Movie in order to get this joke?
This really should be in MPSIMS you stupid fuck wad.
Maybe it’s because it’s the end of the day, maybe it’s because I had little to eat for lunch, but I I have to share my opinion that this statement should be chronicled in dictionaries everywhere as the perfect use of the term fuck wad.
My god, NO! My terrible secreat is out, i knew it could only be so long until i was found out! OH! The shame! The shame of it all!!
Yes, my fellow Dopers, it is true. I, Upham, thought by many of you to be a twisted yet relitivly harmless Canadian goof ball am, indeed…<sob> a small piece of rock.
I know! I know! It’s a shock to many! but it’s the truth, horrid as it may seem
[sub]gad, how will these people ever accept me now…[/sub]
Not to burst your bubble, but spodumene is technically a mineral. It combines with other pedogenic minerals to form a rock.
But it’s a pretty mineral, kinda lilac-ish…
Look Rasa i really think i ought to know what kind of rock i am.
I mean i have been a rock for close to 500,000 years now, so i’ll thank you to keep your foolish little non-rock opinions to your self! (except the “pretty” part, feel free to throw that in any time you want)
But chert is a rock. And don’t you go messin’ with the rocks, pally, or you’ll have me to answer to!
[sub]Not that that means much…[/sub]
::bows out of this thread gracefully at the coming of Geobabe::
Besides, my geological knowledge is limited to the rocks that people made stuff out of. 
A Canadian rock who plays the spoons. Quit Fist Fucking me.
Alright, seeing as my name is in the title and i’m now a rock (and rocks have no sence of manners) i’m gonna hijack a little
IRC; either there’s no one on there right now (which i somehow doubt)
Or.
My computer’s doing like it usually does and is trying to kill me
Or.
I have made my self so much of an ass in my 3 days on IRC that i’ve been either kicked off or everyone’s hiding behing the couch.
Any help here’d be lovely as i curently have absolutly no life what so ever and i’m getting damn bord playing Minesweeper.
Lil’ help?
This made a lot less sense than my thread that was closed.
To you, maybe, you incestuous little worm.
