Found this in a load of gravel delivered for my yard. Live in Tucson, AZ, so assume it came from nearby. What is it?   |

Yep, dwt, looks like you have "Stumped The Board"!
Congratulations! You can pick up your prize the day after
Thanksgiving at the Crabtree Emerald Mine in Little Switzerland, NC! ;D
Seriously tho, I dunno. Agate, Pet Wood, Sandstone???
It looks like it's been tumbled or water worn. That would make a
scratch test trickier.

well, would anyone go for a wierd form of obsidian that has been tumble polished? at least that could account for the molten look and the shine.

My guess is a water worn or tumbled piece of folded schists. Very nice looking specimen.

Since the gravel most likely came from somewhere pretty close to you in Arizona I was thinking of arizona's volcanic past...but now I am going to go with Joe's guess of of sandstone. It looks just like a polished piece of sandstone. Nice guess Joe.

When I found it, it was covered by a thin layer of caliche, but the swirls were evident, so I tumbled it to remove the caliche. It has been sprayed with a clear lacquer to bring out the shine. Can't do a scratch reliably because of this. Don't think sandstone, as it was not at all grainy before spraying. Looks like the folding in the mountains near El Paso in miniature.

dwtdenver, thanx for the info about caliche. I looked it up and believe it could be the substance that covers a layer of rock here. Saskrock maybe knows what I am talking about. The best rocks for cutting seem to be in this layer. The rocks look like they had the tops dipped in concrete.That is a nice piece you have there.

I like the rock. I do find some rocks with crusty stuff thinly covering them here. It floureses green under LW uv. It kind of looks like concrete. Around here though they seem to be like that when they are right on the surface.

The caliche here also typically fluoresces green under short-wave or long-wave UV.
