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

Rare earth elements and yttrium (REY) are critical elements for a wide range of applications
and consumer products. Their growing extraction and use can potentially lead to REY and …

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 …

The discovery of the Gouap banded iron formations (BIFs)-hosted iron mineralization in the
northwestern of the Nyong Group (Ntem Complex) in southwestern Cameroon provides …

Precambrian iron formation provides valuable windows onto ancient marine environments,
but exactly how these Fe-and Si-rich chemical sedimentary rocks formed have remained a …

The biogeochemical sulfur cycle plays a central role in fueling microbial metabolisms,
regulating the Earth's redox state, and affecting climate. However, geochemical …

Paleoarchean jaspilites are used to track ancient ocean chemistry and photoautotrophy
because they contain hematite interpreted to have formed following biological oxidation of …

Astronomical forcing associated with Earth's orbital and inclination parameters (Milankovitch
forcing) exerts a major control on climate as recorded in the sedimentary rock record, but its …

Rare earth elements and yttrium (REY) are often used as proxies for (paleo) environmental
conditions and for the reconstruction of element sources and transport pathways. Many …

Understanding the origin and evolution of life on Earth and potentially other planets in our
solar system is of fundamental interest for humanity. For the longest time in Earth's history …
