The Aguas Zarcas fall produced primarily small stones, the majority of which were unbroken; a rare occurrence due to the violent effects experienced by most meteorites as they blast through Earth’s atmosphere. Meteoriticists noted the stone’s high degree of brecciation. Some stones exhibit clasts with abundant chondrules. Some specimens are rich in nickel-iron and will adhere to a magnet, while others show no attraction. The variation in these specimens is a reflection of the heterogeneity of the parent body, caused by pummeling and re-accretion of other asteroidal material as it hurtled through space.
