Transient Marine Bottom Water Oxygenation On Continental Shelves By 2.65 Billion Years AgoNature Geoscience
A growing body of evidence suggests that molecular oxygen (O2) accumulated in some shallow marine environments beneath the effectively anoxic Archaean atmosphere 4.0 to 2.5 billion years (Ga) ago.

Carbon Dioxide Release From Magma Deep Beneath Ancient Volcanoes Was A Hidden Driver Of Earth’s Past Climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the […]
