These are bands which are usually alternating between kamacite and taenite. Minerals present include taenite, plessite, troilite, chromite, kamacite, and schreibersite. Nickel is commonly found in iron meteorites as the alloys kamacite and taenite. During cooling kamacite is exsolved from taenite. This makes iron the dominant element in any sample of kamacite. It is structurally an ataxite with very rare kamacite lamella. The overwhelming bulk of these meteorites consists of the FeNi-alloys kamacite and taenite. Nickel iron mixtures tend to exsolve into a mixture of iron-rich kamacite and iron-poor taenite. The metal matrix is mostly kamacite with an average nickel content of 6.98 wt%. Kamacite, troilite and chromite are also present. Most of the meteoric iron is kamacite with minor amounts of taenite. The largest documented kamacite crystal measured . There are no planes of cleavage present in kamacite which gives it a hackly fracture. The bulk of meteoric iron consists of taenite and kamacite. The others are kamacite, tetrataenite, and antitaenite.
