Maybe some kind of hematite with something else running thru it.

If you can write with it on concrete (like using chalk), it should be blood red. If it is, i'm 90% sure its hematite.

I have about the same thing. The book I have says it's banded Ironstone, it's red chert with bands of hematite. Have you struck it with steel yet, to see if it sparks?

Let us know how it does, if it don't spark I will take another look in my book to see what else it may be.

Depends on the hardness, could be banded Iron stone. If soft could be mud stone, if hard could be clay stone. looks like there are some microcrystaline structures reflecting back at the camera so could have made the leap from sedimentary to metamorphic, does it foam up when you put a drop of dilute hydrochloric acid on it? then its got limestone in it. who knows. looks cool.
