彭山锡铅锌多矿田, 德安县, 九江市, 江西省, 中国

Sn-Pb-Zn polymetallic ore field, related to the Late Yanshanian calc-alkaline Pengshan pluton of granitic composition. Compositional variation of the ore-forming fluid with decreasing temperature, as caused by action of magmatic hydrothermal and groundwater convection led to various types of mineralization in the ore field. The mineralization process can be divided into six stages: (1) greisenization, (2) early-stage skarnization, (3) fluorite-stanniferous silicification, (4) advanced skarnization stage, (5) quartz and cassiterite-sulfuration stage, and (6) carbonatization. The ores are spatially zoned, with an As-Sn mineral assemblage in the inner zone, through Sn-Pb and Pb-Zn-Ag mineral assemblagess in the middle to a fluorite mineral assemblage in the outer zone.
