Geomagnetic dating of rocks is possible because

Ilya Kupenko from the University of Münster (Germany).The new findings could, for example, be relevant for any future observations of the magnetic anomalies on the Earth and on other planets such as Mars.In the outermost crust of the Earth, rocks cause magnetic signal.In the deeper regions of the Earth's interior, however, it was believed that the rocks lose their magnetic properties due to the very high temperatures and pressures.

Information about the motion of tectonics plates comes from both direct measurement of the plates location during the present day and information about the age and geometry of plate boundaries preserved in the rocks themselves.

This is because Mars has no longer a dynamo and thus no source enabling a strong magnetic field originating from the core to be built up such as that on Earth.

It might, therefore, now be worth taking a more detailed look on its mantle. Background and methods used: Deep in the metallic core of the Earth, it is liquid iron alloy that triggers electrical flows.

The researchers now took a closer look at the main potential sources for magnetism in the Earth's mantle: iron oxides, which have a high critical temperature -- i.e.

the temperature above which material is no longer magnetic.

By then calculating the change in location over a time interval, we can determine the velocity of that point on the plate.
