Coastal wetlands are an important source of methane emissions, and understanding the
mechanisms that control methane emissions from coastal wetlands is of great significance to …

In carbonate rocks, natural production of sulfuric acid can form karstic cavities. Where both
epigenic and hypogenic speleogeneses have taken place, these processes are challenging …

Abstract The Songliao Basin, with an area of∼ 260,000 km 2 in northeast China, hosts the
largest oilfield in China, which is one of the world's most productive oilfields. However, the …

The sulfur cycle is an important part of constructed wetland biogeochemistry because it is
intimately intertwined with the carbon, nitrogen, and iron cycles. However, to date, no …

Gypsum makes up about one fifth of giant salt deposits formed by evaporation of seawater
throughout Earth's history. Although thermodynamic calculations and precipitation …

Viral infections modulate bacterial metabolism and ecology. Here, we investigated the
hypothesis that viruses influence the ecology of purple and green sulfur bacteria in anoxic …

Sedimentary records of superheavy pyrites in Phanerozoic and Proterozoic successions (ie,
extremely positive δ34Spyrite values together with higher δ34Spyrite than coeval δ34SCAS) …

The early evolution of life on Earth was intimately coupled with the evolution of ocean
chemical composition and redox conditions in Archean ocean. However, the measurements …

The mechanism governing sulfur cycling in nitrate reduction within sulfate-rich reservoirs
during seasonal hypoxic conditions remains poorly understood. This study employs nitrogen …

Throughout Earth history, large volcanic eruptions that inject sulfur-bearing gases are
believed to have imparted strong forcings on global climates and ecosystems. Sulfur …
