Scientists have uncovered the world’s oldest oceanic crust in part of the eastern Mediterranean Sea. According to a new study, this undisturbed section of Earth’s outermost shell could be as old as 340 million years. “Changes in the magnetic field’s orientation over time are recorded in the ocean floors, creating a unique bar code that provides a time stamp for crust formation,” study author Roi Granot said.
“The results shed new light on the tectonic architecture and evolution of this region and have important implications on various geodynamic processes.”
