Too Red

If it is reddish, particularly the interior, then it is probably not a meteorite.

And, none of these rocks has a fusion crust.

OK. The astute among you may be thinking, “…but iron meteorites and metal-rich stony meteorites that have been on Earth a long time get rusty colored.” Correct. Here’s an example.

Here is the exterior (left) and interior (right, sawn face) of an unnamed ordinary chondrite from the Sahara Desert. The metal grains have all rusted. This is as “reddish” as a meteorite becomes. If you find a rock this color on Earth, however, it’s far more likely to be a hematite-rich Earth rock than a meteorite.

Hematite-rich Earth rocks.
