Three different types of gold and silver deposits in Zhejiang Province (Huangshan gold deposit, Zhilingtou gold–silver deposit and Haoshi silver deposit) show marked differences in lead and strontium isotopic composition, suggesting three different sources and geneses of these deposits. The Huangshan gold deposit features low initial Sr isotope ratios and low μ values or low content of radiogenic Pb and its ore–forming materials came primarily from the upper mantle; the Zhilingtou gold–silver deposit shows high initial Sr isotope ratios and high μ values or high content of radiogenic Pb and the ore–forming materials were derived mainly from the upper crust; and the Haoshi silver deposit has its Pb and Sr isotope ratios between the above two cases with the ore—forming materials stemming from both the mantle and the crust. The characteristic Pb isotopic composition may serve as an indicator for prospecting for different types of ore deposits.
