Is modern Zealandia an analogue for how ancient continental cratons formed? This large-scale study conducted among some of Earth’s youngest and actively deforming crust with international partners was initiated through my National Geographic Society Waitt Grant. The new findings for Zealandia, Earth’s 8th continent, are fundamentally important to understanding the formation and stabilisation of continental crust on Earth, including its ancient history. The nature of this crust being unique in our Solar System, and also representing the rocky skin on which much complex life and civilisation now thrives on our habitable home world. (This work arose from my National Geographic Society Waitt Grant.)
