The Fe-Zn Isotopic Characteristics and Fractionation Models: Implications for the Genesis of the Zhaxikang Sb-Pb-Zn-Ag Deposit in Southern Tibet

Figure 9

(a) Fe isotopic compositions of pyrite, Mn-Fe carbonate, and arsenopyrite in the Zhaxikang deposit (part of the data is quoted from Wang et al. [26]). Other Fe isotopic data for the Bulk Silicate Earth [10], shale [34, 35], igneous rocks [21–23, 28, 36–45], seafloor hydrothermal fluid system [34, 46–49], midoceanic ridges pyrite [48, 50], the Bayan Obo Fe-REE magmatic-type deposit in China [51], the skarn-type deposits in Tongling ore district in China [21, 22], the Schwarzwald hydrothermal vein deposit in Germany [52], the Renison Sn-W deposit in Australia [23], and the Dongshengmiao SEDEX-type deposit in China [53] are also plotted for comparison. (b) Zn isotopic compositions of sphalerite, Mn-Fe carbonate, and slate in the Zhaxikang deposit (part of the data is quoted from Wang et al. [26]), compared with the Bulk Silicate Earth [54], sedimentary rocks [55–57], igneous rocks [28, 54, 57–60], deep-sea carbonates [61], seafloor hydrothermal fluid system [62], deep sea water [51, 54, 63], and other deposits with different geneses: the Gorno and Raibl magmatic-type deposit in Italy [14], the skarn-type deposits in the Tongling ore district in China [12], the Tianqiao and Bangbangqiao carbonated-hosted Pb-Zn sulfide deposits in China [64], the Irish-type deposit in Ireland [19], the Cévennes MVT deposit in France [65], the Alexandrinka VHMS-type deposit in Russia [18], the Red Dog SEDEX-type ore district in Alaska [20], and the Dongshengmiao SEDEX-type deposit in China [53].
