Meteorite Regmaglypts

Regmaglypts are thumbprint like impressions on the surface of larger meteorites that are formed by ablation of material from the surface as a meteor passes through the Earth's atmosphere. They are probably formed by vortices of hot gas. Here are photographs of a few examples.  Click on image for enlargement.

This large meteorite, Lewis Cliff 85320 (H5 chondrite, (244 lbs) has lots of regmaglypts.

Even this small meteorite (on the ice in Antarctica) has regmaglypts.

This meteorite, with lots of regmaglypts, is about 25 cm wide (10 inches).

Regmaglypts on stony meteorites are shallow.


Regmaglypts on iron meteorites can be spectacular.

Here are small fragments of Sikhote-Alin, an iron meteorite. All of the biggest have regmaglypts. (Photo credit: Randy Korotev)
