Figure 10

Lead isotopic compositions from the Yuka gold deposit. (a) 207Pb/204Pb vs. 206Pb/204Pb and (b) 208Pb/204Pb vs. 206Pb/204Pb. The evolution curves of the upper crust, lower crust, mantle, and orogen are from Zartman and Doe (1981). Data from Paleozoic strata are quoted from Zhu et al. [75]; data from Paleozoic intrusions are quoted from Guo and Chen [76]; data from Proterozoic strata are quoted from Zhang [74].
