Why this rock
is probably not a meteorite:
Because it has the composition of a manganese steel.
This is a great meteorwrong. It has a coating that looks something
like a meteorite fusion crust.
It's composed of metal, but the concentration of nickel is too low
and manganese much to high for a meteorite.
Also,
where
the
"crust" has flaked off, the texture is not like that of
an iron meteorite - it's too grainy. The crust is almost certainly
manganese
oxide, which is black like
charcoal.
