<< Well, if it contains trapped bubbles of Martian atmosphere, there is very
little one can do to disprove it. Also, if it is near identical to the
Apollo samples, there is another clue. >>
Most of the Martian meteorites also have relatively young crystallisation
ages, and if memory serves, as young as 200 million years. At that age,
these didn't come from the asteroid belt.
Take away the asteroid belt as a possible source and alternatives quickly
become limited. A planet with an atmosphere thin enough to allow a rock to be
ejected at high speed without burning up would seem a good candidate though.
