Curie depth

from Wikipedia, the free encyclopedia

The Curie depth is the isosurface under the earth's surface where it is so hot that the Curie temperature of the ferromagnetic minerals in the rock crust is reached.

In the continental crust , this temperature is usually reached at a depth of around 11-20 km, in the oceanic crust, due to the material dependence of the Curie temperature, it is often reached after a few kilometers. The Curie depth is usually determined by aeromagnetic measurements or magnetic measurements with satellites .

Curie depth by region

Measurements taken on Crete showed a Curie depth of 24–28 km.

In Turkey , the Curie depth in the Aegean region is 6-10 km. The highest values ​​are in Turkey at 20–29 km.
