Pb isotope ratios and their variation have been measured and explained on ores of massive S‐Fe‐Au deposits hosted in the Middle‐ Upper Carboniferous, on feldspars from diorite bodies closely related to mineralization and on whole rocks from ore‐hosting strata (carbonate rocks) in the Tongling area, Anhui Province. Through a comparison of Pb isotope features of these geological bodies, it has been suggested that ore substances of the deposits were derived from ore‐hosting strata. In the meanwhile, the measurement of ore Pb isotopes of different mineralization types of the same deposit indicates that different mineralization types have distinct Pb isotope characteristics, showing the potentiality of the Pb isotopic method used in mineral exploration.
