## Identifying global vs. basinal controls on Paleoproterozoic organic carbon and sulfur isotope records

Paleoproterozoic sedimentary successions are important archives of the redox evolution of Earth’s atmosphere and oceans. Efforts to unravel the dynamics of our planet’s early oxygenation from this archive rely on various geochemical proxies, …

## High-CO$\\_2$, acidic and oxygen-starved weathering at the Fennoscandian Shield at the Archean-Proterozoic transition

Chemical weathering of continental crust plays an important role in Earth‘s surface evolution and also controls the nutrient flow to the ocean. Major changes in the development of Earth’s geochemical system were taking place at a critical time …

## Multiple sulphur isotope records tracking basinal and global processes in the 1.98 Ga Zaonega Formation, NW Russia

The exceptionally organic-rich rocks of the 1.98 Ga Zaonega Formation deposited in the Onega Basin, NW Russia, have refined our understanding of Earth System evolution during the Paleoproterozoic rise in atmospheric oxygen. These rocks were formed in …
