Every once in a while I find this type of rock. It isnt flaky at all and might be marble (maybe). I do find white quartz in the area if that helps with the ID on it and its redish brown. Found in N Ga near the mountains. Thank you, rock
well, maybe if you come across another chunk of that stuff, you might do some tests on it. I must say, I've often been happily surprized to find that the inside of a rock is way different from the outside. In my area, I'm surrounded by water/beach environments where all the rocks have oxidised- just like your flint- being so different as it ages. (imagin how increadible that game ball looked when it was new and gleeming). Breaking rock- to me- helps understand whether a rock was imported or local. Some of the material around here doesn't look at all like the points I find, but when I break rock, I find that it is, in fact, local. Light peach-colored rock breaks open to be red or dark brown. Pale grey rock breaks open to black interiors. I would not know that unless I did a little 'damage'. I would have (wrongly) assumed they were trading for or importing rock from some dinstance. Keep in mind too, that no one would have ever found a geod if they didn't break some rocks!
Cheers mate!

Haven't been able to locate any quartzite. But I did find some felsic rock. (probably an altered rhyolite - guessing here)
Just thought it might be of interest for you, it resembles something you posted. Just not sure which topic.
Dang that looks really nice. It really looks good after it is polished. I believe that is close to what I have. I collect red rocks that I find in the same places I find NA artifacts. I picked up another one on Friday when I was hunting a farmers field. I believe the Indians admired the red rocks and found them to be special. I havent found any made to Artifacts as of yet in my area just the rocks in natural state.
Thanks Jim. Yeppers, it is a bit more fine grained.
But I think rock gets the idea, the big honker is just an older pic I digged out rather then taking a new one.
