Sulfur isotopic characteristics of the Zhaxikang Sb–Pb–Zn–Ag deposit in southern Tibet

In the Zhaxikang deposit, the ore minerals include sphalerite, pyrite, galena, arsenopyrite, chalcopyrite, stibnite, cinnabar and sulfosalt minerals (boulangerite, jamesonite, bournonite, freibergite, tetrahedrite, andorite and zinkenite), and the gangue minerals comprise Mn–Fe carbonate, quartz and calcite. The formation of these minerals has been assigned to two hydrothermal events that are subdivided into six stages based on hand specimen and ore microscopic observations (Figure 2). The first pulse of mineralisation consists of stages 1 and 2, and the second pulse of mineralisation contains stages 3–6.
