FIG. 3. Photomicrographs in reflected light showing paragenetic relationships of ore minerals in Larga ores. (a) Inclusions of gold (Au) within an intergrowth of arsenopyrite (Apy) and relict löllingite (Lo). Sample: 52 (0 Est gallery). (b) Association of tellurides in pyrite (Py) and arsenopyrite (Apy) within typical vein mineralization. Ttd: tetradymite, Hs: hessite, Ts: tsumoite. Sample: 3M (Vein 37 at 625 m, 0 Vest gallery). (c) Inclusions of tetradymite (Ttd) within a matrix of arsenopyrite (Apy) and pyrite (Py). Note the co-existence of hessite (Hs) and galena (Gn). Sample: 3M (Vein 37 at 625 m, 0 Vest gallery). (d) Typical occurrence of bismuth sulphosalts, in this case dominantly composed of Sb-bearing lillianite (Li) as inclusions in chalcopyrite (Cp). Sample: 145 (vein in Padina gallery). (e) Association of gold (Au) and rucklidgeite (Rkl) in quartz within the Trîmpoiele porphyry deposit. Sample: T960. (f) Inclusions of chalcopyrite and pyrrhotite crystallized from intermediate solid solution (Cp/Po) within Hanes veins dominated by sphalerite (Sp). Sample: 1963.
