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

Abstract: Based on previous research on the Fe isotope compositions of various components and systems of the Earth, this study focused on the Fe isotope compositions of hydrothermal systems, including the Fe isotope variations in chalcopyrite, pyrite, and sphalerite, and their possible controlling factors. The main findings are as follows: (1) 56 Fe values of pyrite/marcasite display a larger range than those of chalcopyrite. This pattern is directly related to equilibrium fractionation or kinetic fractionation of Fe i… Show more

“…Typically, such hydrothermal fluids are enriched in light Fe isotopes (e.g. δ 56 Fe = ~ -1.26 to -0.14 ‰ [35][36][37][38] ). According to experimental data 39 , iron in hydrothermal Cl-bearing fluids occurs mainly as FeCl 2 0 , which has strong capability of carrying ferrous iron (Fe 2+ ).…”
