Stony irons
Stony-irons are mixtures of silicates and free metal (iron-nickel) in approximately equal proportions. They are rare among falls but somewhat more common among finds because of the ease with which they can be distinguished. The stony-irons are divided into three main groups: pallasites, mesosiderites, and lodranites. Other groups exist, but they comprise unusual and rare specimens and will not be described further here.
