Hi there. I wanna know about this community. I'm an student of Earth Sciences which loves everything related before the Cambrian. So, I would like to know if I can share (and what kind of) info about Proterozoic, Archean, Hadean and Chaotian Eons. Thanks and have a wonderful day.

Geoscientists have discovered that the earths core formed under more oxidized conditions. They did it through laser experiments. I thought for a long time that the early earth had little oxygen.
