The host-microbiome supraorganism appears to have coevolved and the unperturbed
microbial component of the dyad renders host health sustainable. This coevolution has likely …

Iron (Fe) minerals play an important role in stabilizing soil organic carbon (SOC). Fe-
mediated SOC protection is mainly achieved through adsorption, co-precipitation, or …

Many iron (Fe) redox processes that were previously assumed to be purely abiotic, such as
photochemical Fe reactions, are now known to also be microbially mediated. Owing to this …

Iron is the most abundant redox‐active metal in the Earth's crust. The one electron transfer
between the two most common redox states, Fe (II) and Fe (III), plays a role in a huge range …

Iron formations (IF) represent an iron-rich rock type that typifies many Archaean and
Proterozoic supracrustal successions and are chemical archives of Precambrian seawater …

Iron formations are economically important sedimentary rocks that are most common in
Precambrian sedimentary successions. Although many aspects of their origin remain …

Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Iron (Fe) has long been a recognized physiological requirement for life, yet for many
microorganisms that persist in water, soils and sediments, its role extends well beyond that …

The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth
history. It allowed life to generate energy and reducing power directly from sunlight and …

Construction and assembly of the Geologic Time Scale involves:(a) constructing a relative
(chronostratigraphic) standard scale for key periods in the Earth's rock record;(b) identifying …
