Evolution of Earth’s oxygenation and temperature depends on surface carbonate accumulation
Nature » Geoscience

5d ago
Nature Geoscience, Published online: 11 April 2024; doi:10.1038/s41561-024-01429-x There are no good models for the chemical evolution of the Earth’s surface over the planet’s lifetime, because models typically overlook the progressive build-up of carbonate rocks in the crust. A new model that includes this accumulation enables the reconstruction of major oxygen and temperature trends throughout Earth’s history ..read more
