Mineral–microbe interactions play important roles in environmental change, biogeochemical
cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical …

Two records of Earth history capture the evolution of life and its co-evolving ecosystems with
interpretable fidelity: the geobiological and geochemical traces preserved in rocks and the …

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

The chemistry of Fe and Mn in natural geochemical systems are closely coupled, as Fe and
Mn always co-exist in various forms (eg, hydrated ions, soluble complexes, and particles) in …

The provenance of GoM45 and GoM63 core sediments recovered in the deep-sea area (∼
1666 m–1672 m water depth, respectively), in front of the Los Tuxtlas volcanic field, Gulf of …

Microfossils, stromatolites, preserved lipids and biologically informative isotopic ratios
provide a substantial record of bacterial diversity and biogeochemical cycles in Proterozoic …

The Curiosity rover observed high Mn abundances (> 25 wt% MnO) in fracture‐filling
materials that crosscut sandstones in the Kimberley region of Gale crater, Mars. The …

Animals originated and evolved during a unique time in Earth history—the Neoproterozoic
Era. This paper aims to discuss (1) when landmark events in early animal evolution …

Manganese and iron are redox-sensitive elements that yield clues about biogeochemistry
and redox conditions both in modern environments and in the geologic past. Here, we …

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 …
