Light oxygen isotopic composition in deep mantle reveals oceanic crust subduction before 3.3 billion years ago
Abstract Compositional heterogeneity exists in Earth’s deep mantle, which can be caused by the subduction of oceanic slabs. How early this process started on Earth remains highly debated due to the scarcity of early Archean materials with pristine mantle compositional signatures. Here, using the oxy...
