Mesoproterozoic (ca. 1140-1120 Ma) carbonatite (ferrocarbonatite) dykes transect anorthositic rocks of the Kunene Intrusive Complex in an area of 10 x 10 km.
The ferrocarbonatite is mainly composed of ankerite and magnetite, and is highly contaminated by fragmented and fenitized wallrock anorthosite (albite, biotite and sodalite), with Fe-Cu-Ni sulfides (assemblage: pyrite, chalcopyrite, millerite, polydymite, fletcherite) being widespread minor components (Drüppel et al., 2006).
