Taenite is a mineral found naturally on Earth mostly in iron meteorites. It is an alloy of iron and nickel, with a chemical formula of Fe,Ni and nickel proportions of 20% up to 65%.
The name is derived from the Greek ταινία for "band, ribbon". Taenite is a major constituent of
Widmanstätten patterns, whereas in ataxites it is the dominant constituent. In octahedrites a fine intermixture with kamacite can occur, which is called plessite
.
Taenite is one of four known Fe-Ni meteorite minerals: The others are kamacite, tetrataenite, and antitaenite.
Properties
It is opaque with a metallic grayish to white color. The structure is isometric-hexoctahedral (
Strunz classification is I/A.08-20, while the Dana
classification is 1.1.11.2.
