Abstract:

Native copper occurs in some of the Tafelberg basalts of the Etendeka Formation which have been described in detail by Erlank et al. (1984). The copper was first recognised during mineral separation work on four samples where it occurs as a few irregular grains in the non-magnetic fraction of the crushed basalt, in some cases adhering to feldspar and pyroxene. Electron microprobe analysis has confirmed that the material is pure Cu with no significant concentration of other elements. It is highly unlikely that the copper is a contaminant from a previously processed sample which was introduced into the basalt during sample preparation because the basalts in which it has been identified were processed at different times.
