I came into a a bunch of this material from my brother the driller while he was testing the stability for wind farms in Minn. It looks pretty neat but I can't find alot of info on it which leads me to think that there is a reason. The cores are "drillbit" polished and look like they would take a nice shine. Anyone help ? Pics later today hopefully.

Well, I have no clue what they are... the middle one sort of looks like petrified wood... how far apart were the drill holes? Were they from the same geographic region? Any clue how deep these were found?
What it looks like to me is they'd be really easy to make spheres out of... orrrr... you can slab em in 1/4" slices and have perfectly round preforms for the tumbler or polishing:) (no idea what the diameter on them are from the pix)!

Any clue what part of Minnesota these came from? The one on the left could be Red Jasper. Not sure about the one in the middle, but I agree the lines look woody. The one on the right looks like Stromatolite, but I could be way wrong. The drill gave 'em a nice polish. Is the color in the picture pretty accurate?
Looking at them again I see they're wet. Jo

Whatever it is it looks cool. Being MN I wonder if the center is a type of Dolomite.

Wow, those are great looking! I'm not very good with identification beyond the common types. Out of curiosity, how large are those pieces? Properly polished, I bet they'd make great display pieces.

Since most of the SoCal hound sites are picked clean, maybe we all should invest in core drills?!?!

Well I spoke with the brother again, these all came from somewhere north of Laverne, MN. He said that they had a geologist onsite that indicated this was Red Quartzite. I guess it took them forever to go down an inch. The size of the cores are about 2" wide. Some of them are different but for the most part they are smooth and will take a good polish it looks like. There are a few he said were pipestone but I have yet to get into that box. Now I just need to get my saw from it's current home 5+ hours away in WI.
Thanks for the look and comments !
