Mesosiderites

The silicate phase in mesosiderites consists mostly of hypersthene pyroxene and plagioclase feldspar (as opposed to olivine as in the pallasites), and often includes abundant troilite (FeS). Unlike in the pallasites also, the metal phase in mesosiderites does not form a continuous matrix of free metal. Instead, the mixing between the silicate and metal phases is more intimate.
