Chemostratigraphy and Biostratigraphic Correlation: Exercises in Systematic Stratigraphy [PDF]

, 1981
Global changes in marine geochemistry, on scales between one thousand and one million years permit the detailed correlation of sedimentary sequences in different ocean basins. The condition is that the geochemical signals are at least approximately dated by biostratigraphy (and magnetostratigraphy, where applicable).

Large igneous provinces played a major role in oceanic oxygenation events during the mid-Proterozoic

Communications Earth & Environment
Low atmospheric oxygen levels during the mid-Proterozoic were occasionally interrupted by transient high oxygen levels. The cause of mid-Proterozoic ocean redox variability remains unclear.
