Abstract
Jinding is the largest Zn-Pb deposit in China, and also the yougest sediment-hosted super-large Zn-Pb deposit in the world. The Jinding mineralization processes are discussed in this paper based on the investigations of the mineral intergrowth. The hydrothermal mineralization experienced three stages: the stage of quartz sphalerite-galena, the stage of sphalerite-galena-celestite and the stage of galena-calcite-celestite-gypsum. Fluid inclusions in sphalerite and associated gangue minerals show that the homogenization temperatures range from 54° to 309°C and cluster around 110°∼150°C, with salinities of 1.6∼18.0 wt% NaCl equivalent. The temperature increased and the salinity decreased during the early stage, the temperature was stable and the salinity decreased during the main stage, and both temperature and sality decreased during the final stage. This temperature-salinity trend probably resulted from mixing of a high-temperature, low-salinity fluid with a low-temperature, high-salinity fluid during mineralization.
