| Abstract | Authigenic pyrite often develops extensively in marine sediments, which is an important product of sulfate reduction in an anoxic environment. It has a specific appearance and complicated sulfur isotopic properties, and acts as important evidence of methane seep in marine sediments. Strong AOM (anaerobic oxidation of methane) activity has developed in the Okinawa Trough. Owing to the inconvenient geochemical sampling, few studies have been conducted on the pyrite and its sulfur isotope based on an AOM-development setting. This work analyzed the characteristics of authigenic pyrite and its sulfur isotopic values with an AOM background in the middle Okinawa Trough. We discussed how the changes in the pyrite and its sulfur isotope content affect the anaerobic oxidation of methane and the methane flux. |
