Abstract The Xiabao large-scale Ag-Pb-Zn deposit is located in the southwestern Lengshuikeng ore field ,Jiangxi Province. The
major mineralization can be divided into three stages :sphalerite-pyrite polymetallic stage (stage );galena-sphalerite-silver minerals
Ⅰ
polymetallic stage (stage );pyrite-quartz (calcite)stage (stage ). The major ore minerals include sphalerite,galena ,pyrite and
Ⅱ Ⅲ
silver minerals are studied in this paper on petrography and analyzed with Electron Probe Micro Analysis (EPMA). The EPMA also
indicates that the most Ag presented in the ores occurs mainly as independent silver minerals ,and rare Ag in sulfi
