Absence of hexavalent chromium in marine carbonates: implications for chromium isotopes as paleoenvironment proxy
The oxygenation of Earth's atmosphere is widely regarded to have played an important role in early-life evolution. Chromium (Cr) isotopes recorded in sedimentary rocks have been used to constrain the atmospheric oxygen level (AOL) over geological times based on the fact that a positive Cr isoto...
