Description
During the Archean (~4 – 2.5 Ga) the relative balance between chemical weathering, tectonism, and volcanism likely contrasted from today given the expected evolution of the crust-ocean system over such a duration of Earth history. The effects of this dynamic interplay on ocean composition can be investigated using geochemical and isotopic approaches applied to well-characterized suites of chemical sedimentary rocks, which provide an archive of the compositional evolution of Earth’s oceans.
