Rare earth element and yttrium (REY) concentrations of carbonates can be used as potential
proxies to trace the geochemistry of precipitating waters and physico-chemical …

The presence of exposed land on the early Earth is a prerequisite for a certain type of
prebiotic chemical evolution in which the oscillating activity of water, driven by short-term …

It is generally accepted that photosynthetic marine planktonic bacteria were responsible for
the oxidation of dissolved ferrous iron (Fe (II)) and the subsequent deposition of iron …

Mass-independent fractionation of sulfur isotopes (MIF-S) in Archaean sediments results
from photochemical processing of atmospheric sulfur species in an oxygen-depleted …

Previously reported stable Cr isotopic fractionation in Archaean paleosols and iron
formations (IFs) have been interpreted as a signature of oxidative weathering of Cr (III) to Cr …

The rare earth elements and yttrium (REY) can enter carbonate lattices by replacing cations,
which can be used to reconstruct the history of carbonate precipitation. The Ediacaran …

Abstract The Rare Earth Elements (REE) archived in carbonate rocks retain a wealth of
information on paleo-seawater chemistry and local-regional redox conditions. However …

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 …

Rare earth elements and yttrium (REE+ Y), with stable and predictable chemical
characteristics, serve as important proxies for diagenetic fluids, but the effect of …

Modern biological dependency on trace elements is proposed to be a consequence of their
enrichment in the habitats of early life together with Earth's evolving physicochemical …
