The Mengxing Pb–Zn deposit, which contains up to 1.02 Mt of Pb + Zn metal with an average Pb + Zn grade of ca. 12.13 %, is a representative of sedimentary–reworked deposit in western Yunnan. The deposit is comprised of 45 strata–bound orebodies in the Silurian Shangrenheqiao formation. The mineralization process has been divided into sedimentary stage and hydrothermal stage. The pre–enrichment of metals of early stratified Sedex–type ore–bodies is crucial for the formation of the Mengxing deposit.
This stratigraphically and structurally controlled deposit boasts a significant extension of the ore bearing zone, spanning approximately 10 km, and is characterized by a large number of ore bodies (up to 45) with relatively high grade (average Pb + Zn grade of 12.13 %) and associated useful elements such as Ge, Cd, Ag, Tl, and Bi. The strata–bound, lens–like, pod–like, and veined ore bodies are hosted within the strata and inter-layer fracture zone of the lower member of the Middle Silurian Shangrenheqiao formation.

Three stages of mineralization have been identified at Mengxing, including pre-ore, syn-ore and post-ore. The pre-ore (diagenetic) stage is characterized by some sulfides (eg. euhedral pyrite) which occur as laminated or disseminated in the wall rocks. The syn-ore stage is further divided into stage I and II. Stage I is featured by the mineral assemblage of pyrite, sphalerite, calcite, barite, quartz and minor galena. Pyrite (Py-I) in this stage is colloid and euhedral. Sphalerite (Sp-I) is reddish, fine-grained, and grew with calcite, barite, and quartz. Stage II is characterized by veined and disseminated mineralization, with mineral assemblage of galena, sphalerite, calcite and quartz. Sphalerite in the stage II (Sp-II) is yellowish, coexisting with calcite and quartz, and cut earlier stage minerals. Stage II galena generally replaces the earlier Py-I and Sp-I. Py-II occurs as xenomorphic filling among Sp-I grains. The post-ore stage is characterized by calcite/dolomite veins with no metallic mineralization.
