In China, Lengshuikeng is the only deposit of this type. Based on a study of the Lengshuikeng porphyry Ag-Pb-Zn deposit in such aspects as its fluid A inclusion geochemistry and stable isotope geochemistry in combination with lithologic investigation, Raman probe (LRM) and scanning electron microscopy / energy (SEM / EDS) analysis, the authors revealed characteristics of the ore-forming fluid and the evolutionary process in this deposit. The ore-forming materi
