The metallogenic mechanism of the Jinding Zn-Pb deposit is always of catholic concern, but it cannot reach a consensus. One of important causes is ascribed to limiting understanding in ore-forming fluid properties and its sources. It is discovered that both vein and nodule calcites are characterized by sharing sharp right-dipped chondrite-normalized REE patterns with LREE enriched and LREE-HREE distinctively differentiated, as well as similar Mg, Fe and Mn contents. Besides, carbon isotopes spread dispersively(δ¹³CPDB=-22.95‰~-2.56‰), indicative of carbonic multi-sources for vein calcites, but concentrate (δ¹³CPDB=-7.02‰~-6.18‰) for nodule calcites. Two groups of oxygen isotopes (δ¹⁸OSMOW=20.16‰~23.49‰) resemble sedimentary rocks. To be comprehensively analyzed, vein calcites and nodule calcites, both due to hydrothermalism, represent two different hydrothermal systems: early ore-forming fluid resulting from multi-sources with deep components added in and late ore-forming fluid dominated by meteoric water.
