Hi,
        According to Alan E. Rubin & Jeffrey N. Grossman: "A meteorite is a
natural, solid object larger than 10 ?m in size, derived from a celestial
body, that was transported by natural means from the body on which it formed
to a region outside the dominant gravitational influence of that body and
that later collided with a natural or artificial body larger than itself
(even if it was the same body from which it was launched)." Using that
definition I would say that your rock should be called a meteorite. I also
think that a cool name for a new class of meteorites would need to be
created. I just hope that we could have that class created before 5 examples
of it were recognized.

Thanks,

Peter

IMHO - This should most likely be called 'Earthite'. A whole new class of
rocks distinct from meteorites, which so far we don't have any of (unless
anyone knows different!?).

 Or they could just be known as Tektites, since that is essentially what the
consensus is on Tektites. Though I would put Tektites in the group of
Ancient impact glasses rather than actual fusion crusted rocks from earth.

Suppose a fusion crusted stone is found shortly after a fireball. When
examined it shows a celestial age of a few million years and a relatively
short formation age. More examination shows it to be a stone formed on
earth, ejected into space and returned here. Is it meteorite or a
meteorwrong. Or something in between?
