Electron microprobe determinations of Si in the metal of 19 iron meteorites, including representatives of the nine chemical groups, reveal Si concentrations below our detection limit (about 25 ppm) in all but two cases. The two objects are Tucson, an iron of anomalous composition containing highly reduced silicate inclusions, and Horse Creek, a meteorite which is more appropriately classified with the enstatite chondrites than with the iron meteorites. We conclude that most (probably more than 99 %) of the iron meteorites contain less than 30 ppm Si in the metal, and that meteoritic evidence for the presence of Si in the earth's core is very weak. Some details regarding the structures and composition of Tucson are given.
