A strange magnetic anomaly deep beneath East Antarctica has finally been explained by an international team of geologists. By drilling over 500 meters through solid ice, scientists uncovered ancient rocks linked to a lost volcanic island that collided with Antarctica nearly a billion years ago. This dramatic event happened during the formation of the supercontinent Rodinia, reshaping Earth’s crust in ways still detectable today. Lab analysis revealed how these rocks formed, transformed, and carried magnetic signatures across vast geological time. Watch now to uncover how this hidden collision rewrote Antarctica’s past and revealed secrets buried beneath kilometers of ice.
