“The Aguas Zarcas meteorite fell in Costa Rica on 23 April 2019 at 21:07 local time, with a total mass of about 27 kg. Hundreds of fusion-crusted stones ranging from 0.1 to 1868 g were recovered (The Meteoritical Bulletin). The meteorite was classified as a CM chondrite, but some lithologies show a different texture to that of CM. In this study, we investigated the petrography, mineralogy, chemistry, and isotopic composition of an unusual “metal-rich lithology” from this fresh fall.
