Pelitic ores are the equivalent of organic-rich shales (orange) and are associated with chemogenic ores (black). Gamsberg is interpreted as distal ore with respect to the main fault related feeders compared to the proximal ores of Broken Hill-Deeps and Swartberg. The heat source is a deep-seated basaltic magma which extruded after deposition ofthe Gams Member (Stalder, 2004; Stalder and Rozendaal2004b).
