    What is this rock? My detector is picking it up.

    Can anyone tell me what this rock is? I'm thinking it's granite, maybe? I've posted a video of it....

    Dig it up.....you'll always wonder what is was if you don't!

    Re: What is this rock? My detector is picking it up.

    I Don't think Granite has metal in it.
    at least not naturally.
    I also don't think Gold, since you maxed disc .
    other then that I can't help exept too ask
    are you absolutely sure it's not Cement
    with a coin, Piece of Wire or Brass in it ?

    My guess would be some kind of slag.

    @Jeff according to the internet, granite has metallic properties.

    @Swartz isn't slag black?

    I don't know...thanks for the responses.

    Re: What is this rock? My detector is picking it up.

    Well, first off it DOES look like a granite type of rock and not concrete.
    Slag could be any color based on what metal the slag is coming from, but that's not slag.
    Since it's just a rock, take a hammer to it! Find out WHAT is causing the response.

    metallic minerals within the rocks "make up" cause a "hot rock' effect -- (ie) it rings up due to mineral content within the rock

    It looks like some of the HOT ROCKS I have run across while prospecting out west. They usually contain iron. I am surprised no one asked. Did you test it with a strong magnet? Frank

    Put the rock in the microwave & cook it for about 30 minutes.....see if you're microwave starts sparking...& still works after the 30 minutes. Then afterwards.....instead of "hot potato".....you can play "hot rock"......bet the rock stays hot longer than a potato anyway...

    Nice try, and an intelligent thought. But please look again. My right hand doesn't have a ring. My wedding ring is on my left. The rock is where it's coming from.
