Enhanced phosphorus regeneration linked to Ediacaran ocean oxygenation

Communications Earth & Environment
Several pulses of ocean oxygenation events were recognized in the Ediacaran period. However, the intrinsic triggers behind them remain ambiguous. Here we report phosphorus speciation data from the Ediacaran Doushantuo Formation, South China, to elucidate

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]

, 2007
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.
