    Hi everybody, I have been searching the internet and no luck on Identifying this rock I found with my metal detector. It is a very flat dull black on the outside and when I broke it open it was very smooth and shiny on the inside the light reflects off of it making it look like specks of silver. Like I said It would set off my metal detector. So just out of curiousity I would like to know what it is . Here is a picturerock 001.JPG

    I would off hand guess an iron pyrite within the rock.
    But I post mainly to bump the thread and see if some of the more geologically savvy take a gander.

    Bits of obsidian or some other type of volcanic glass embedded inside the crust?

    I disagree with seagypsy on this. The specimen, looks to be either the tail end of and obsidian flow with the buff section being a weather worn surface and the broken side being a fresh surface. Alternatively it could be a bituminous resin of some type such as Uintahite Uintahite: Uintahite mineral information and data. Could you get images of it in focus by chance?

    I agree with Paleoichneum mainly because he knows more about this stuff than I do. However, the remarks I made were in regards to the photo I posted, not the one in the op. It was meant as a comparison. lol.

    Hmm rereading your initial post I had another thought. Were you by chance metal detecting near a mining or industrial area?

    Ahhh, so you are actually are in an area that I would expect to find possible slag type materials, keeping in mind that the Northern part if the state is home to the Minnesota iron belt mines.
