Oxygenation, life, and the planetary system during Earth's middle history: An overview
The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

Uranium isotopes in marine carbonates as a global ocean paleoredox proxy: a critical review
The protracted oxygenation of the ocean-atmosphere system is one of the most fundamental
changes to the Earth system through its history. The uranium isotopic composition (238 …

Extensive marine anoxia during the terminal Ediacaran Period
The terminal Ediacaran Period witnessed the decline of the Ediacara biota (which may have
included many stem-group animals). To test whether oceanic anoxia might have played a …

Global marine redox changes drove the rise and fall of the Ediacara biota
The role of O2 in the evolution of early animals, as represented by some members of the
Ediacara biota, has been heavily debated because current geochemical evidence paints a …

A pulse of oxygen increase in the early Mesoproterozoic ocean at ca. 1.57–1.56 Ga
The relationship between oxygen and evolution of early eukaryotes including algae and
primitive animals in geological history has been debated, partly due to the varying estimates …

[BOOK][B] Iron geochemistry: an isotopic perspective
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 …

Controls of eustasy and diagenesis on the 238U/235U of carbonates and evolution of the seawater (234U/238U) during the last 1.4 Myr
Using a leaching protocol designed for the study of U isotopes in recent carbonates, we
measured the U isotope composition, both 238 U/235 U and 234 U/238 U, of modern and …
