Outline of Final Research Achievements

To reconstruct the secular change of CO2 levels in the atmosphere and ocean through the Earth history, we analyzed fluid inclusions retained in hydrothermal quartz deposits that precipitated within open spaces of oceanic pillow lavas from 12 areas with 9 ages in the world. As a result, we revealed that sufficient greenhouse effect was maintained by the atmospheric CO2 to compensate the faint young sun in the early to middle Archean and that CO2 levels in the atmosphere and ocean drastically decreased from the late Archean to the early Proterozoic. These results suggest that the decrease in CO2 levels in the atmosphere and ocean was caused by the first appearance of the supercontinent and its breakdown and that the drastic drawdown of CO2 levels lasted until 2.2 Ga and likely triggered the global glaciation.
