File:BSE images of pampaloite from the Svetlinsk deposit.png

English: Backscatter electron (BSE) images showing the pampaloite assemblages from the Svetlinsk deposit. (a) Pampaloite (grain A) coexisting with native gold intergrown with tetrahedrite-(Fe) and chalcopyrite. (b) Intergrowth of pampaloite (grain B) with petzite among the crystals of löllingite with rhomb-like sections. (c) Pampaloite (grain C) overgrowing native gold in the complex assemblage of tellurides (altaite, petzite, hessite) and sulfides (tetrahedrite-(Fe) and chalcopyrite). (d) Anhedral pampaloite grain (grain D) in petzite associated with chalcopyrite. Elongate inclusions of tellurantimony at the contact of pampaloite and petzite. (e) Pampaloite (grain E) surrounded by petzite. Petzite along with altaite and calaverite fill a crack in quartz. Chalcopyrite occurs at the contact of petzite and quartz and forms inclusions in petzite, sometimes with sphalerite. (f) Enlarged fragment of Figure 1e with pampaloite. Elongate grains of tellurantimony occur along the contact of pampaloite and petzite. (g) Pampaloite (grain F) inclusion in quartz together with altaite, petzite and native gold. (h) Intergrowth of pampaloite (grain G) with hessite on the right. On the left side, pampaloite forms a border between hessite and aurostibite. (i) Pampaloite (grain H) inclusion in petzite. Au-Ag tellurides (petzite, sylvanite, hessite) and altaite overgrow early pyrite. (j) Enlarged fragment of Figure 1i with pampaloite and altaite inclusions in petzite. The matrix is quartz for all images.
