Deoxygenation is a critical problem facing the ocean as the world warms, and has the
potential to effect coastal upwelling zones, shelf areas influenced by high runoff and …

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 …

Many late Neoproterozoic to early Cambrian fossils of multicellular eukaryotes, including
those of benthic animals, are found preserved under anoxic and even euxinic bottom-water …

Fine-grained sediments in the Ordovcian–Silurian (OS) Longmaxi Formation on the Yangtze
Platform represent a significant shale gas source and reservoir in South China. The …

The Neoproterozoic oxygenation event (NOE) likely began earlier than 800 Ma, raising
oxygen levels in the Earth's atmosphere-ocean system and, thus, setting the stage for the …

Molybdenum (Mo) geochemistry is widely used to reconstruct ocean oxygenation throughout
Earth's history. However, gaps in our fundamental knowledge of Mo burial within sediments …

CO2 is considered the main greenhouse gas involved in the current global warming and the
primary driver of temperature throughout Earth's history. However, the soundness of this …

Abstract The Ordovician-Silurian transition (OST) is a critical geological interval, during
which dramatic climatic, environmental and biological changes occurred. Although …

Mangrove forests are known as coastal carbon sinks, but the long-term (millennium-scale)
preservation processes of organic matter (OM) in their soils and the role of sulphur in these …

We document chemostratigraphy in an outcrop of late Albian to early Campanian (∼ 103–
82 Ma) marine source rocks to better understand paleoenvironmental controls on trace …
