I think that some meteorites are original cosmic dust, others are planetary fragments kicked up by impacts during formation, and still others are fragments kicked up by impacts after formation.

Van Flandern was on Coast this week with his exploding planet hypothesis. The asteroids and the other pieces that we see as meteorites seem to have been part of a planet that broke apart. It's an old idea, except for the part where Mars was a moon of this exploded planet. Perhaps this exploded planet was a gas giant, too, and all that is left is pieces of the rocky core. It's at the distance-from-the-sun junction where rocky planets and gas giants meet.
