Geology, Palaeontology & Archaeology / What gives a rock a dark, rusty interior?
« on: 18/12/2015 18:02:40 »
This was found in the southeastern part of the United States. You can see the size of the rock from the pictures, about the size of your fist. It weighs about 2 pounds and has a few interesting characteristics:
1) It fits your hand like a tool using the 'bottom side' as a tool that might smash or break something.
2) The bottom side looks as if it was purposely made for this purpose.
3) There is rust-dust on a few locations suggesting that this has an iron core. I do not have a strong magnet but the small one I do have does exhibit force when placed near the rock.
Now, I'm a biologist and from what I gathered, this is a typed of layered metamorphic rock. I am thinking that this might have been formed from a meteorite strike that somehow formed a rock layer on its surface.
I'll stop there before I make too much more of a fool of myself and see how the responses go. I have yet to take it to a local university mainly because there is not a full geology department here.
Thanks
