Fe Isotopic Compositions of Modern Seafloor Hydrothermal Systems and Their Influence Factors

Figure 1

Fe isotopic composition of each repository. (The gray color column shows the Fe isotope composition of basalt with an average value of + () [10]; the black rectangle shows the average value of δ⁵⁶Fe. All data from the literatures: river [3, 4, 11, 12]; ocean water [13–16]; oceanic sediment [6, 7, 12, 17]; hydrothermal sulfide [6, 18–20]; hydrothermal fluid [6, 7, 19–21]; Fe-Mn noddle and crust [8, 22–24]; deposit [25–31]; banded Fe formations [32–42]; carbonate rock [36, 43, 44]; loess/dust [6, 31, 45]; shale [6]; metamorphose rock [46]; basalt [32, 33, 45, 47–53]; mantle peridotite [32, 33, 45, 47–52, 54, 55]; meteorolite [24, 33, 34, 49, 50, 56–62].)
