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

Greigite (Fe3S4) is an authigenic ferrimagnetic mineral that grows as a precursor to pyrite
during early diagenetic sedimentary sulfate reduction. It can also grow at any time when …

This paper presents a reformulation of the submarine alkaline hydrothermal theory for the
emergence of life in response to recent experimental findings. The theory views life, like …

In many anoxic sedimentary environments, the onset of sulfate reduction, and pyritization of
detrital iron-bearing minerals, leads to a precipitous decline in magnetic mineral …

Sedimentary greigite (Fe3S4) is being increasingly implicated as the carrier of late
diagenetic remagnetizations in fine-grained marine and terrestrial sediments. We have …

First‐order reversal curve (FORC) diagrams have become a standard tool in rock
magnetism, yet magnetite is the only magnetic mineral that is well characterized using …

Mineral magnetic results and electron microscope observations from gas hydrate-bearing
marine sediments cored at southern Hydrate Ridge during Ocean Drilling Program Leg 204 …

Detailed rock magnetic and electron microscope analyses indicate that the magnetic
signature of Neogene marine sediments from the east coast of New Zealand is dominated …

The magnetic domain state of a material determines its magnetic recording capability and
magnetic properties. Constraining the domain state of magnetic components within …

Continental shelves serve as a bridge between the continent and ocean and sediments in
this region are sensitive to land-sea interaction, sea-level variation and local subsidence. In …
