FIG. 11. Application of the geothermometric method based on the composition of coexisting stannite-sphalerite pairs in altered skarn ores from Larga. (a) and (b) BSE images showing two examples of stannite-sphalerite pairs used for geothermometry. Abbreviations: Sp: sphalerite, Stn: stannite, Qz: quartz, Cal: calcite, Se-Gn: seleniferous galena. Sample 71 (0 Est gallery). (c) Compositional data plotted on isotherms according to the calibration of Nakamura and Shima (1982) cited by Shimizu and Shikazono (1985). Smaller grains (e.g. a), give temperatures close to 350°C.
