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." Click on Term to Read More, 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 Click on Term to Read More 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 Click on Term to Read More; its name is derived from the Greek word for “beam.”
