Global marine redox evolution from the late Neoproterozoic to the early Paleozoic constrained by the integration of Mo and U isotope records
The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Recurrent photic zone euxinia limited ocean oxygenation and animal evolution during the Ediacaran
Abstract The Ediacaran Period (~ 635–539 Ma) is marked by the emergence and
diversification of complex metazoans linked to ocean redox changes, but the processes and …

Episodic ventilation of euxinic bottom waters triggers the formation of black shale-hosted Mn carbonate deposits
Many manganese (Mn) carbonate deposits over geologic history are often closely
associated with black shales. However, the mechanism (s) by which the Mn entered the …

Upwelling-driven high organic production in the late Ediacaran
Abstract The Ediacaran ocean (635-541 million years ago) is typically viewed as a stagnant,
redox-stratified ocean with low phosphorus availability. However, this contradicts the high …
