What can sedimentary rocks known as “cherts” reveal about the early Earth?

Rocks store information from long ago. They can reveal the environmental conditions during their formation, which led researchers to investigate further. They found that #OxygenIsotopes in cherts record how much heat was released from the hot interior of the Earth to their location on the seafloor.

This helped researchers understand conditions on the Earth's surface around 3.5 billion years ago: https://www.uni-goettingen.de/en/3240.html?id=7940
