Anyone know what this stone is???

[dtinhb]

Hey all.... So this is interesting one. In the first picture below, you will see what it looked like in the ground. From the outer edge of the orangish-brown area on top was all that was exposed in the dirt. When I pulled it out, the stone was already broken in half. The last picture is of the side I tried to sand down with my sander... The red I think is from the sand paper. I am going to try to clean up a bit and take more pics. The rock is not attracted to magnets and kinda has a slate like feel to it, but a much more solid composition. This rock is heavy and more dense than any of my other finds. Let me know what you think! Thanks!

Well the red is not from sand paper, but rather looks like some type of rust. Here are some pics wet, after I scrubbed them a bit.

It kind of looks like some kind of chert or low-grade jasper, hard for me to tell, I think I might see a few concoidal fractures? Those would be my guesses, but hopefully some one with better knowledge could help you!

This is left field but it resembles a rock that had been under a hot camp fire.

Yeah, I could see that... But it was buried with only the top 3" diameter of rock showing. The black mark is a chip from the rock that's missing.. just as an FYI.

@IAMZIM I don't think it's either of those. The red on the stone looks more like rust than the anything/ The fractures in the bottom-middle of the stone I thought looked like they originate from some type of impact. I would swear it was a meteorite if it was magnetic. I guess it could have fell from cliff or something like that, but I pretty sure there were no cliffs in the near by area. I of course am guessing just like you, with my only advantage being that I have the rock in my possession.

I am interested to know if the white material around the internal nodes is quartz or calcite. From the looks of it I feel its a sedimentary concretion. The red is likely iron oxides which are common to many concretions. The clean breaks on the horizontal plane, rounded shape and internal nodes all lend to my feeling on the stone. Low grade cherts can have similar appearance but typically don't fracture on a clean plane in the banded varieties.

Don't take this wrong, but it looks very wrong for a meteorite, even a stoney one.

Not taken wrong at all... We're all here for perspectives. I actually agree with you. My statement was if the rock was magnetic I would have sworn it was a meterorite. It's not, so I make no such claim.

@DDancer- It looks more like quartz to me, but see for yourself.

I'm with DDancer on this one. Looks to me like a concretion. The vein formed from mineral precipitation after fracturing.

Roughly where was it found? Looks like a rhyolite or as IAMZIM suggested, a jasper like thing.

I am not sure exactly, but somewhere between Southwestern Utah and South Eastern Colorado. I grabbed so many rocks along the way, I don't know which is from where.
