Chert oxygen isotope ratios are driven by Earth's thermal evolution
The (18)O/(16)O ratio of cherts (δ(18)O(chert)) increases nearly monotonically by ~15‰ from the Archean to present. Two end-member explanations have emerged: cooling seawater temperature (T(SW)) and increasing seawater δ(18)O (δ(18)O(sw)). Yet despite decades of work, there is no consensus, leading...
