Queensland Was Once Connected To Canada: The Georgetown Inlier

Beneath the quiet town of Georgetown in north Queensland lies a geological secret: a fragment of Canada. Known as the Georgetown Inlier, this ancient block of crust began its life as part of Laurentia, the heart of North America, before drifting away and colliding with Australia 1.6 billion years ago. Its rocks preserve the isotopic fingerprints of Canada’s Wernecke Supergroup, offering a rare glimpse into the assembly of Earth’s early supercontinents.
