Please help indentify this rock.

[superior digger]

Found in the Upper Peninsula of Michigan. VERY heavy for its size. I had part of it cut and it was EXTREMELY hard to cut with a 24 inch diamond blade saw. Vey smooth to the touch . It was in high elevation so i am guessing it was moved and deposited by the glaciers.

I'd be willing to bet it's hornfels. Looks a lot like a much smaller piece i have from lower peninsula MI

Luster and blocky appearance is the same too

 

[stdenis_jd]

can you post a pic of the cut side, if you were able to get it cut of course

See the green and black striped one in this pic? That's hornfels, looks nearly identical to what you have there
