Biogeochemical cycle of chromium isotopes at the modern Earth's surface and its applications as a paleo-environment proxy
Chromium (Cr) is a redox-sensitive metal element with two natural oxidation states,
commonly as the soluble Cr (VI) oxyanion (CrO 4 2− or HCrO 4−) and the insoluble Cr (III) …

A transient swing to higher oxygen levels in the atmosphere and oceans at~ 1.4 Ga
Abstract The mid-Proterozoic (1.8–0.8 Ga) may have witnessed persistent and predominant
anoxia at the Earth's surface. However, recent studies suggest that there was a period …
