The class of Stony-iron meteorites is a loose category in the classic science of meteorites, in which all meteorites were summarized that approximately consist of equal shares of metal e.g. nickel-iron and stone. Nowadays most researchers include only two groups of meteorites in the stony-irons, Pallasites and Mesosiderites, although there are enough reasons to expand this category with some groups that usually are listed as stony- or iron meteorites, as they fulfill all criteria, that make them to real Stony-irons. For this reason, these groups are also described further below.
