Help Rock ID
« on: March 10, 2010, 01:11:22 pm »
I just got a rock from a friend that hikes out west. I took a spall off one corner an man is this stuff hard. Colors are a blueish green grey an dull black, This rock was picked up in Utah, an its hard hard hard :o  I believe it will knap but I may have change up my tools a bit. Any ideas or help greatly appreciated. I got an idea as to what it is but I'll wait on some western input. Thanks Again Bob

Why do you say crappy agate ??

Im not being sarcastic, I used to do quite a bit of rock tumbling and any agate would always polish great.....I know nothing about knaping

Looks like some kind of metabasalt. The greenstone/metabasalt stuff in Virginia that they make the peck-and-grind axes out of looks similar to that, and it'll flake with wood.

Brian , I'm going to have to go with yours. I took a potato sized hammer stone an gave it a heck of a wack an my wrist, elbow an fillings are still rattling. I thought it was some kind of ryolite but don,t know if they have it in Utah. I got a pc of reddish ryolite that was from NM. or Ariz. an it's pretty hard an I've hit a few pcs from North Carolina. HillBilly will a pc of english box elder work for a billet on this hard stuff? Maybe an ole fart like me should just trade it off to some youngster thats all musculed up an don't know anybetter ;D or I could just go fishin >:D Thanks for all your help with this specimen. Bob

 PD, didn't say, Crappy agate. I said crappy basalt or crappy jasper. Or as Claude VanOrder used to call it, Leaverite.
