Kamacite

More common than taeniteLess common than kamacite, both taenite and kamacite are Ni-Fe alloys found in iron meteorites. Taenite, γ-(Fe,Ni), has 27-65 wt% Ni, and forms small crystals that appear as highly reflecting thin ribbons on the etched surface of a meteorite; the name derives from the Greek word for "ribbon.", both taenite and kamacite are Ni-Fe alloys found in iron meteorites. Kamacite, α-(Fe,Ni), contains 4-7.5 wt% Ni, and forms large body-centered cubicWay in which atoms or ions (considered as hard spheres) pack together to fill space. In BCC packing, the spheres in Layer A are separated slightly and the spheres in Layer B are offset so that they fit into the depressions between atoms in Layer A. Each sphere is touched crystals that appear like broad bands or beam-like structures on the etched surface of a meteoriteWork in progress. A solid natural object reaching a planet’s surface from interplanetary space. Solid portion of a meteoroid that survives its fall to Earth, or some other body. Meteorites are classified as stony meteorites, iron meteorites, and stony-iron meteorites. These groups are further divided according to their mineralogy and; its name is derived from the Greek word for “beam.”
