Evidence of Fluctuating Paleoatmospheric Oxygen Levels Before and After the Cryogenian Marinoan (Snowball Earth) Glaciations

Chromium isotope, REE and redox-sensitive trace element chemostratigraphy across the late Neoproterozoic Ghaub glaciation, Otavi Group, Namibia Authors: Rodler et al Abstract: Chromium isotopes constitute a powerful paleoenvironmental tracer recording fluctuations of atmospheric oxygenation and continental weathering thus facilitating the reconstruction of the redox state of ancient seawater.
