Nickel and Iron, Ni and Fe
- This medium octahedrite was found in the Nullabor Plain of Western Australia in 1966. It is the most
easily recognized type of meteroite, an "iron". Okay, I know, it's not a terrestrial mineral... but it is a rather
exotic rock and I just couldn't resist including this handsomely sculpted specimen.
- The other two major classifications are "stony irons"
and "stone" meterorites. The stones are futher classified as either chondrites or achondrites.
The presence of the nickel-iron alloys kamacite and taenite is the most outstanding difference
between meteorites and terrestrial rocks, in which they occur only very rarely.
