Can anyone ID this rock. Actually found it walking down old highway by my house. Was completely buried except for tiny part that shimmered in the sunlight. I live in Texas if that helps any. The panhandle. Thanks for any help

You found the work of the Jesuit's. Second picture give their signature hat. If placed in the right light you can see the details on it. You will have others tell you different. Looking at it carefully you can see the work on it. Your in prime country for their larger work. It get bigger the closer you get the the mountains. It could be a trail marker.

And I decoded the Beale papers... sheesh.

Got some nice green and what looks like blue in one picture. Some one in the past chopped a bit off (second picture). Because of the blue and green I'm inclined to think you have a malachite/turquoise mix thats heavy on the silicates. Might have some lapidary value. The south west is good for that type of material.

Why would any theologians bust up rocks just to throw them around w/o a purpose? Why not just do the simple thing of carving in a rock, we were here? Kilroy Was Here?
Go ahead and dismiss me as someone that just doesn't get it. And I'll dismiss you the same.

I couldn't help but to see from my monitor partially decomposed granite.
Need a little forensic help from the OP.

DD might be on to something.

Yes,while I don't see turquoise from here the green mineral can't be dismissed. And I think it would hold up up slicing to see what happens.
Cutting a slab is always risk and reward considering the stone has been quiet so long.

I was thinking more in the lines of chalcedony, silica-rich thing. I'll not even start speculating on the cause of the greenish colour.

From where I'm sitting the first picture in the second row~ just right of center and extending vertically is a run of blue and to the right bits of blue in the green as well. This mix is common for copper malachite and turquoise though the lower part of the blue maybe more of an azurite from its apparent graininess. Thats not uncommon either as the blue is extending into the host rock and out of the silicate mix on the top. EU is correct in that the silicate is most likely chalcedony as one can see where the green is capped by translucent chalcedony in the part that was cut.

It looks a little like Slag from a mining/smelting operation but that is frankly just a observation from having found some before that was somewhat similar...

Blue is from the blue emitting light hitting the rock, the rest is common chalcedony.

 

[DDancer]

Does not seem that way to me Moesia. Have to be a pretty strong source of light to do that. Common chalcedony is white to opaque with a waxy luster, unlike opal that has a hard luster. When high levels of chalcedony are present in copper minerals the mix leads to cutting grade and gem grade minerals of which I described. More common malachite and low grade turquoise are much softer.

4-th picture, look at the table (bottom left corner) ...

Your right Lowman, it's slag. And if you found that one. There are plenty more. I find them often. They got to get rid of the slag some way.

Color has nothing to do with it...

If it indeed was the lightning the white balance of the camera would be off & everything would be more on the blue side.
Don't think that's the case.
