Thermochemical sulfate reduction (TSR) is a set of redox reactions between organic matter
and sulfates at temperatures> 120° C, and occurs in varied environments including deeply …

Transient appearances of oxygen have been inferred before the Great Oxygenation Event
(GOE)[∼ 2.3 billion years (Ga) ago] based on redox-sensitive elements such as Mo and S …

Serving as an adsorbent and a reductant for the dissolved U, pyrite is abundant and
commonly found associated with U minerals in sandstone-hosted U deposits. Different …

Iron is a remarkable element in its relatively high abundance for its mass and its sensitivity to
(and control of) redox on a planetary scale over geologic time. Numerous volumes have …

Theoretically, within the long-term marine sulfur cycle, pyrite sulfur isotopes (δ 34 S py) are
determined by the degree of pyrite burial that is controlled by the marine redox conditions …

The Neoproterozoic sulfur isotope (δ34S) record is characterized by anomalously high
δ34Spyrite values. Many δ34Spyrite values are higher than the contemporaneous …
