Sodium plagioclase and small amounts of potassium feldspar are common constituents of silicate inclusions in the Weekeroo Station and Colomera iron meteorites; flamboyant x-ray antiperthite is unique to Kodaikanal silicate inclusions. Enrichment of potassium, sodium, silicon, and aluminum in these inclusions indicates a higher degree of chemical differentiation than in other meteorites.
