and a submission to the Meteoritical Society's naming committee for approval. The other most common mineral that you will find sticking to your magnet while hunting is Magnetite. Mesosiderites have a silicate portion made of mainly igneous rock fragments and are likely formed by collisions between asteroids that are rich in metal and rich in silicate.
They include meteors and fireballs (1).
If it isn’t magnetic, it probably isn’t a meteorite.
Each of these words can be used to talk about rocks from space, but they refer to very specific and distinct stages in a rock's journey through space. Our scientists and their partners in Australia have triangulated the most likely fall zone for August's fireball to be southwest of Camrose, Alberta.
Here are those spots after grinding. If you file or grind on them they will show metal like any piece of iron from your garage or a junkyard that is rusted. This is the kind of marks meteorites have sometimes on their exterior surface. The absence of regmaglypts does not mean a specimen is not a meteorite.
