The special and representative polymorphous pyrites of the Logatchev area, Mid-Atlantic
Ridge, have a close evolution relationship. There are relatively complete pyrite …

As important metal sulfides in the geochemical cycle of sulfur, the characteristics and
formation processes of pyrites can provide useful clues regarding their environment. Based …

Sedimentary pyrite and the ratio between organic carbon and pyrite sulfur (C/S ratio) have
been widely used as paleosalinity indicators to distinguish between marine and freshwater …

Carbon and sulfur preserved in estuary and shelf sediments play a critical role in controlling
sediment diagenesis related to the global biogeochemical cycle. Their ratio (C/S= 2.8) in …

As an important product of methane seepage, pyrite contains abundant methane seepage
information. It is right that the formation mechanisms of authigenic pyrite at methane …

Marine authigenic pyrite sulfur isotope (δ 34 S pyr) is one of the most important proxies for
reconstructing remarkable changes of Earth's surface in deep time. Recent observations of …

Globally, research aiming to reveal the unique biogeochemical processes and gas hydrate
potential in methane seep areas is well established. Furthermore, methane seeps …

Sulfate reduction is a commonly reported process in a variety of continental margin settings
that affects the carbon (C), sulfur (S), and iron (Fe) marine sedimentary cycles. However …

To better understand the depositional constraints on the fingerprint characteristics of
methane isotopes, we present a set of carbon/hydrogen isotopic data for CH4, CO2, pore …

Abstract Iron (Fe), sulfur (S), and molybdenum (Mo) geochemistry in marine sediments
impacted by hydrothermal plumes and/or cold seeps is complex and has not been …
