Meteorites from Atacama (Chile) and Lut (Iran) deserts were selected. Microscopic observations to study the alteration mineralogy were conducted.Stone Meteorites. The largest group of meteorites is the stones, and they once formed part of the outer crust of a planet or asteroid. Many stone meteorites-particularly those that have been on the surface of our planet for an extended period of time-frequently look much like terrestrial rocks, and it can take a skilled eye to spot them when meteorite hunting in the field. Regmaglypts. 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.
