All the photos below were sent to me by people who thought the rocks had regmaglypts. None of these rocks are meteorites – none has a fusion crust. Some terrestrial processes lead to rocks depressions that can look very much like meteorite regmaglypts. Many of these features are the result of sculpting by wind or water on Earth. Some of the depressions are incipient vesicles. Preferential weathering occurs when softer material weathers away before harder material. This process seems to occur most commonly in sedimentary rocks. Another process is “plucking” in which hard, rounded clasts fall out of a softer matrix leaving a rounded depression.
