Scientists may have discovered the world's oldest arc-slicing fault in Northwestern Australia's remote deserts. The finding demonstrates that plate tectonic processes were operational at least 3 billion years ago, fueling the ongoing scientific debate.
"This study clearly demonstrates horizontal plate movements before 3 billion years ago," study co-author Timothy Kusky, director of the Center for Global Tectonics at the China University of Geosciences, told Live Science.
