DescriptionMineralogy and Distribution of Critical Elements in the Sn–W–Pb–Ag–Zn Huanuni Deposit, Bolivia - Figure 4b (cropped).png |
English: Figure 4. Photomicrographs of Zn-rich base metal associations in the Huanuni deposit. (A) Chalcopyrite disease textures in sphalerite that replace earlier pyrite in the Bonanza area; RPPL. (B) Stage-2 base metal sulphides with exsolved černýite from sphalerite in the La Suerte area; back-scattered electron (BSE) image. (C) Stage-2 base metal sulphides in the Bonanza area; notice the passive precipitation of sphalerite after pyrite; BSE image. (D) Stage-2 base metal sulphides in association with phyllic-alteration minerals in the La Suerte area; notice the reactive precipitation of sphalerite after pyrite and the occurrence of apatite; BSE image. (E) Stage-2 rutile associated with quartz and wurtzite in the La Suerte area; BSE image. (F) Stage-2 base metal-rich association with sphalerite partly replaced by chalcopyrite, cassiterite, and stage-3 stannite rimming potassium feldspar (potassic assemblage) in the Central area; BSE image. |
