A. Typical Pb-Sb-Au vein of the stage 3 from SADC. Wall rocks (to the left) are rich in sphalerite (Sp) and galena (Gn) whereas vein centre (to the right) shows sulfosalts (here boulangerite, Blg) and tobelite (Tob) enclosed within a quartz gangue. B. Polished thin section microphotograph (reflected polarized light) of boulangerite (Blg) and electrum (El) of the stage 3 assemblage at SADC. C. Quartz vein with sphalerite in the Armorican quartzite. D. SADC76 sample consists of quartz vein with tobelite crystals. E. Sample rock of Armorican quartzite with veinlets of quartz, chlorite (Chl), tobelite. F. Zoom of mineralogical association of chlorite, tobelite and quartz.
