Reduction–oxidation (redox) reactions occur during burial because sediments contain
reactive mixtures of oxidised and reduced components. Diagenetic chemical reactions …

Earth is one of the inner planets of the Solar System, but–unlike the others–it has an
oxidising atmosphere, relatively stable temperature, and a constant geomagnetic field …

Geological heritage sites (geosites) are sites that contain information about the state and the
dynamics of the Earth. Paleogeographical (paleoenvironmental) geosites preserve …

Fossil biominerals and fossils of microorganisms in ancient rocks contain important
biogeochemical signals. Decoding this record may reveal crucial information about the …

Magnetotactic bacteria (MTB) are unique in their ability to synthesize intracellular nano‐
sized minerals of magnetite and/or greigite magnetosomes for magnetic orientation. Thus …

Reconstruction of oceanic redox conditions across the Palaeocene-Eocene Thermal
Maximum (PETM,∼ 55.93 Ma) provides crucial information on potential PETM triggers and …

Understanding marine environmental change and associated biological turnover across the
Palaeocene–Eocene Thermal Maximum (PETM;~ 56 Ma)—the most pronounced Cenozoic …

Reconstructions of ocean oxygenation are critical for understanding the role of respired
carbon storage in regulating atmospheric CO2. Independent sediment redox proxies are …

Pelagic carbonates are deposited far from continents, usually at water depths of 3000–6000
m, at rates below 10 cm/kyr, and are a globally important sediment type. Recent advances …

Unambiguous magnetic mineral identification in sediments is a prerequisite for
reconstructing paleomagnetic and paleoenvironmental information from environmental …
