Regmaglypts are shallow depressions or dimples that form on the surface of some meteorites as they pass through Earth’s atmosphere. They are probably formed by small vortices of hot gas carrying small droplets of molten meteorite that locally erode the surface.
If a rock has features like dimples, depressions, or pits but it does not have a fusion crust, then the features are not regmaglypts. Many terrestrial rocks have features that resemble regmaglypts but are not meteorite regmaglypts.
