Photomicrographs taken from thin sections (a, b, c; reflected light), and SEM-BSE (d, e, f), illustrating representative textural and mineralogical features of first ore trend minerals at Tabakoto. (a) A pyrite grain in metarhyolite, displaying a subhedral texture and showing evidence of partial alteration, next to euhedral arsenopyrite. Pyrrhotite and visible gold occur as inclusions within the pyrite. (b) Textural relationships between pyrite and arsenopyrite grains in a metarhyolite dike. Note the visible gold grain at their contact. (c) Arsenopyrite rods (euhedral, hence likely retrograde) intergrown with pyrrhotite. (d) Loellingite and gold grain included in pyrrhotite in a metadacite. (e) Arsenopyrite in meta-andesite, with an inclusion containing native silver, bismuth, pyrrhotite and chalcopyrite. (f) Native gold particles included in pyrite. Abbreviation: Ag: silver; Apy: arsenopyrite; Au: gold; Bi: bismuth; Ccp: chalcopyrite; Gn: Galena; Lo: loellingite; Po: pyrrhotite; Py: pyrite.
