Three partially weathered rocks were collected between 400 and 430 cm (15HG-38), 430-460 cm (15HG-39), and at ∼500 cm (15HG-B1) (Table S1). Among them, samples 15HG-38 and 15HG-39 are yellowish indicating strong weathering, while sample 15HG-B1 has gray-black color with a number of voids on the surface suggesting weak weathering.No interest in weathered chondrites, HED achondrites and mesosiderite stony-irons.

During the impact of a meteorite, old rocks are broken apart and new rocks are formed. Most lunar meteorites, many HED meteorites (howardites, eucrites, and diogenites), one martian meteorite, and some chondrites are breccias – rocks composed of fragments of older rocks that have been broken apart and relithified (“glued” …On freshly fallen meteorites fusion crusts are usually smooth and glassy, although they might be rougher if the meteorite broke apart during atmospheric entry.
