Germanium associated with the bulk sphalerite and high Fe-low Ge spots has GeS 2-type spectral feature with the peak shifting to higher energy by ∼1 and ∼1.5 eV, respectively (Fig. 7 D). As a result, sphalerite and galena (Fig. 20.21) can be detected down-ice from these deposits using both till geochemistry (Fig. 20.14) and indicator mineral methods. Secondary minerals such as smithsonite formed from the oxidation of sphalerite, and anglesite as well as cerussite formed from the oxidation of galena may also be useful indicator minerals in …The Trepča Mines ( Albanian: Miniera e Trepçës, Serbian: Рудник Трепча / Rudnik Trepča) is a large industrial complex in Kosovo, located 9 km (5.6 mi) northeast of Mitrovica.

PolishedRoughJewelry. Sphalerite makes an excellent collector’s stone, but it is too soft for jewelry. It is difficult to cut and polish due to perfect cleavage in six directions. Gemstone-quality material, when faceted, is remarkable due to its incredibly high dispersion.Sphalerite from Dalong gives a Rb-Sr isochron age of 151.6 ± 7.1 Ma, consistent with the mineralization age of Xiangdong. Both the W–Sn and Pb–Zn ore-forming events are closely related to Late Jurassic magmatism, which occurred in an environment of lithospheric extension and thinning.
