We compare the petrogenetic and chemical signatures of two alkali silicate suites from the Cretaceous Damaraland igneous province (Namibia), one with and one without associated carbonatite, in order to explore their differences in terms of magma source and evolution. The Etaneno complex occurs in close spatial proximity to the Kalkfeld bimodal carbonatite-alkali silicate complex, and is dominated...
The Okorusu fluorite deposit occurs in Pan-African carbonaceous rocks of the Damara Sequence in northern Namibia. The epigenetic mineralization formed from fluids expelled from the Cretaceous Okorusu carbonatite, which is part of the Damaraland igneous province related to the South Atlantic oceanic opening. The fluorites contain abundant high-field-strength elements ( REE=80-285 ppm, Sr=1900-2500...
