BUILDING OF A CONTINENT
ANCIENT rocks in remote Western Australia have revealed how the tectonic plates of the Australian continent were formed, a study has found.
Uranium-lead dating of rock minerals revealed the landscape of the East Pilbara was formed 3.6 billion to 3.4 billion years ago.
Lead researcher Daniel Wiemer, from the University of WA, said the study was based on the oldest parts of the earth’s crust to be found in the region. By recreating the event, researchers were able to witness how plates were formed.
