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.

kg of iron meteorite shrapnel , ranging in mass from < 1 to
35,000 g, plus a single 83 kg individual completely covered with
well developed regmaglypts, was found in and around the 45 m
diameter Kamil impact crater by an Italian-Egyptian geophysical team
