Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small ...

A new geological study reshapes the timeline of a major tectonic collision that helped form the Andes, suggesting key events occurred earlier than long assumed.

Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and seemingly chaotic shifts unlike anything seen before or since. A new study ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of the planets magnetic field. Data from the European Space Agency's Swarm ...
