If a rock has coarse surface or internal swirly features, then it is not a meteorite

back to “Some Meteorite Realities”

Meteorites do not have bent or folded internal layers. Such rocks are terrestrial metamorphic rocks.

Meteorites do not have swirly features on the surface. For small meteoroids, ~90% of the mass is lost to ablation as they come through Earth’s atmosphere. Any such features on the surface would be obliterated.

All of the photos below were sent by persons inquiring whether the rock in the photo is a meteorite. None of them is a meteorite. Note than none of them has a fusion crust.
