ABSTRACTAverage analyses are given by type and as a whole for iron meteorites (siderites, Si), based on selected analyses of 327 siderites. Average compositions are given also for pallasites (P), mesosiderites (Ms), and for the metallic part of chondrites (C). The composition of meteoritic iron appears to be very nearly the same, regardless of whether it occurs alone or in combination with silicate material.
