Wallrock Alteration and Metallogenic Stages of Pb-Zn Deposits in the Sichuan-Yunnan-Guizhou Border Area Southwest China

Abstract:

This paper described the wallrock alteration and mineralization of Pb-Zn deposits in the Sichuan-Yunnan-Guizhou border area Southwest China, and summarized the wallrock alterations what are obvious, which include dolomitization, calcitization, pyritization, carbonation, ferritization, silicification and decolourization. In addition to dolomitization and calcitization,other wallrock alteration are associated with the formation and enrichment of Pb-Zn ore. Meanwhile, based on statistic analysis in mineralization age, and combined with the characteristics of Pb isotope, we confirmed four stages of mineralization in study area.
