AbstractAn interesting fragment of the Toluca, Mexico, sideritic shower (ECN = +997,194) is described. It is interesting from the viewpoint of the concentration of minor meteoritic constituents in abundance and from the viewpoint of structure. The principal constituent is kamacite, but the fragment contains macroscopically visible schreibersite, graphite, troilite, daubréelite, and lawrencite. One (1) figure and 4 tables are given
