Mössbauer spectroscopy is used to quantify how much iron exists in what oxidation states in a sample ... microbes have a direct effect on rock weathering—that bacteria oxidize iron, leading ...

The study, "Pyrite oxidation drives exceptionally high weathering rates and geologic CO 2 release in mountaintop-mined landscapes," was published in the journal Global Biogeochemical Cycles.

This is because the Precambrian sulfur cycle was dominated by a reduced sedimentary reservoir (pyrite), which after surface oxidation in weathering was soon reduced again and buried, whereas the ...

Like S355 J0WP, S355 J0W is a weathering steel and is an equivalent to Corten B. As the material rusts when exposed to atmospheric elements, the material builds its own protective layer which prevents ...
