- The rocks provide early evidence of plate tectonics, which explains Earth's crust as split into large plates that glide across the mantle.
- The rocks also point to what conditions may have been like when life first evolved.
- This discovery has made while investigating the Barberton Greenstone Belt, a complex geological formation in southern Africa.
- The belt is remarkably similar to much younger rocks in New Zealand.
- They have experienced earthquake-triggered submarine landslides along the Hikurangi subduction zone.
