A New Depositional Framework for Massive Iron Formations After the Great Oxidation Event
Abstract The oldest recognized proxies for low atmospheric oxygen are massive iron‐rich deposits. Following the rise of oxygen ∼2.4 billion years ago (Ga), massive iron formations (IFs) largely disappear from the geologic record, only to reappear in a pulse ∼1.88 Ga, which has been attributed to sea...
