Great Oxidation Event - Wikipedia
The Great Oxidation Event (GOE) or Great Oxygenation Event, also called the Oxygen Catastrophe, Oxygen Revolution, Oxygen Crisis or Oxygen Holocaust, [2] was a time interval during the Earth's Paleoproterozoic era when the Earth's atmosphere and shallow seas first experienced a rise in the concentration of free oxygen.

Evidence that the GOE was a prolonged event with a peak
2022年5月1日 · The great oxygenation event (GOE), the first of two major rises in atmospheric oxygen in Earth history, was initially placed near the Archean-Proterozoic boundary (∼2500 Ma). More recently, the position of the GOE has been moved to between 2500 and 2300 Ma so as to coincide with the loss of the MIF sulfur isotope signal due to the creation of ...

大氧化事件 (Great Oxygenation Event, GOE)，是指约26亿年前，大气中的游离 氧 含量突然增加的事件。 这一事件的具体原因尚不得知，只有若干种假说能加以解释。 有说法认为，是由于 海藻 类植物进行光合作用，使得地球上的氧气迅速增加，而破坏氧气的 甲烷细菌 所依赖的 镍 元素的数量急剧减少，使得大气中的含氧量大量增加，所以称为“大气氧化事件”。 大氧化事件使得地球上 矿物 的成分发生了变化，也使得日后 动物 的出现成为了可能。 2019年9月2日，中英科学家发 …

2019年3月5日 · The Great Oxidation Event (GOE), an event marking the rise of oxygen in the early Earth’s atmosphere, is estimated to have happened between 2.5 and 2.3 billion years ago.

2016年2月9日 · None was as all encompassing as the Great Oxidation Event (GOE), a geological episode occurring around 2.35 billion years ago. With the GOE, the atmosphere switched from being oxygen free to having a small percentage of oxygen that would hold for 1.5 billion years, at which point a second leap in oxygen occurred, around 700 million years ago.
Great Oxygenation Event: What Was It And How Did It Affect Life?
2021年3月2日 · Evidence of the Great Oxygenation Event (GOE) can be clearly seen in banded iron formations containing oxidized iron. The GOE allowed respirators or oxygen-using organisms to inevitably...
The Great Oxidation Event: How Earth’s Atmosphere Became …
The history of life on Earth saw many pivotal moments, but perhaps none, other than the origin of life itself, is more significant than the Great Oxidation Event (GOE). Marking the period when the early Earth’s atmosphere started to fill with free oxygen, the GOE set the foundation for the rise of aerobic life and ultimately, present-day ...

2020年12月13日 · The Great Oxidation Event (GOE) refers to the transition from the mildly reducing Archean atmosphere-ocean system to the oxygenated atmosphere and shallow oceans of the early Paleoproterozoic that started between ~2.4 and 2.3 Ga and ended between 2.1 and 2.0 Ga (Holland 2002). The beginning and the end of the GOE were never explicitly defined.

2020年6月1日 · The inability to resolve the exact temporal relationship between two pivotal events in Earth history, the Paleoproterozoic Great Oxidation Event (GOE) and the first “snowball Earth” global glaciation, has precluded assessing causality between changing atmospheric composition and ancient climate change.
