The origin and degassing history of the Earth's atmosphere revealed by Archean xenon
The composition of the early Earth’s atmosphere remains unclear. Here, the authors using fluid inclusions trapped within quartz crystals show that at 3.3 Ga the atmosphere had a lower129Xe excess than today, and suggest that comets may have brought xenon to the Earth’s atmosphere during terrestrial...

| Sumario: | The composition of the early Earth’s atmosphere remains unclear. Here, the authors using fluid inclusions trapped within quartz crystals show that at 3.3 Ga the atmosphere had a lower129Xe excess than today, and suggest that comets may have brought xenon to the Earth’s atmosphere during terrestrial accretion. |
