Copper and zinc have been determined in ten carbonaceous, six enstatite, and five ordinary chondrites by neutron activation techniques. Copper is enriched in all carbonaceous and enstatite chondrites (relative to the ordinary chondrites), while zinc is enriched in all carbonaceous and some enstatite chondrites. The Cu / Zn ratio is highly variable among these chondrite groups indicating a fractionation of copper from zinc at some stage of their history. A very serious sample inhomogeneity was found to exist in the determination of these elements; thus, caution must be exercised in attempting to draw detailed conclusions from those (as well as previously published) data.
