Iron Meteorites

Iron meteorites are composed largely of nickel-iron metal, and most contain only minor accessory minerals. These accessory minerals often occur in rounded nodules that consist of the iron-sulfide troilite or graphite, often surrounded by the iron-phosphide schreibersite and the iron-carbide cohenite. Despite the fact that some iron meteorites contain silicate inclusions, most have fundamentally the same superficial appearance.

Presently, iron meteorites are classified under two established systems. Just a few decades ago, iron meteorites were exclusively classified according to the macroscopic structures revealed when their polished surface was etched with nitric acid. Depending on these structures, they were separated into three classes: octahedrites, hexahedrites, and ataxites.
