English: Figure 6. Backscattered electron photomicrographs of the noble metal minerals. (a) = a large crystal of kotulskite (Kt) in bornite (Bn) [18]; (b) = an intergrowth of electrum (Elc), kotulskite (Ktu) and sopcheite (Sop) in bornite surrounded by an aureole of Au- and Ag-bearing bornite (possibly due to a signal from an ”appearing through” Au-Ag phase); (c) = rounded inclusion of sopcheite in bornite; (d) = an intergrowth of sopcheite, temagamite (Tem) and atheneite (Atn) in a bornite–chalcopyrite intergrowth; (e) = an intergrowth of temagamite and electrum [18]; (f) = a needle-like intergrowth of temagamite and merenskyite (Mrk) in a bornite grain; (g) = small inclusions of potarite (Ptr) scattered in a bornite–chalcopyrite intergrowth; (h) = silver native (Ag) in chalcopyrite; (i) = a small bornite-hosted inclusion of electrum.
