摘要：
The timing of onset of modern-style plate tectonics on Earth is debated. Analysis of rocks in the West African metamorphic province, which is more than 2 Gyr old, reveals that some minerals formed under conditions similar to those in modern-day subduction zones, suggesting that subduction occurred on the Palaeoproterozoic Earth.
