| Why this rock is probably not a meteorite:
1) This rock contains metallic iron (the shiny areas) and is magnetic,
as do many ordinary chondrites. However, we analyzed the metal and
it contains only a very low concentration of nickel, <1%. Metal
in meteorites has 5% or more nickel.
2) The rock contains vesicles and meteorites don't have vesicles.
|What is it?
This is a piece of slag. The presence
of vesicles means that this "rock" was once molten and that
gas bubbles were trapped inside. With very few exceptions, asteroidal
meteorites were never molten.
