Why this rock is probably not a meteorite:

This thing contains a lot of metal. The finder didn't tell me where he got it, but he followed my advice and had a chemical analysis done. It's mostly silica and iron. There's not enough nickel and cobalt to be a meteorite, and there's much-too-much manganese (4.4% MnO) and silica (80% SiO2).
What is it?

Hard to say, but with that much manganese, it's probably man made.
