Earth's oldest mantle fabrics indicate Eoarchaean subduction
Subduction is a main component of Phanerozoic plate tectonics, although the timing of initiation is controversial. Here, the authors present microstructural data from two 3.72 billion year old dunite lenses of Isua in Greenland, which suggest that subduction was already in operation during the Eoarc...

Summary: | Subduction is a main component of Phanerozoic plate tectonics, although the timing of initiation is controversial. Here, the authors present microstructural data from two 3.72 billion year old dunite lenses of Isua in Greenland, which suggest that subduction was already in operation during the Eoarchaean. |
