| Abstract: | Recently, a new epithermal Ag deposit was discovered in the Niankeng area of the southern Jiangxi Pro-vince, South China. The Niankeng Ag deposit is hosted in a breccia pipe, which was cemented by the manganese-rich carbonate species (Mn-dolomite-kutnohorite-rhodochrosite-Mn-calcite)-quartz-muscovite-Ag-bearing sulfosalt (tetrahedrite-argyrodite)-sulfide (argentite-galena-translucent sphalerite-pyrite)-natural silver. The deposit is characterized by intermediate sulfidation. According to geochronologic studies, the Niankeng Ag deposit was formed in the Triassic (Indosinian), and is the first discovered and reported intermediate sulfidation epithermal Ag deposit in the South China. Studies of the mineralization ages and ore characteristics of the Niankeng Ag deposit are conducive to explore the Indosinian intermediate sulfidation epithermal Ag deposits and related porphyry Mo and Sn deposits in the South China. |
