El paleomagnetismo es la rama de la geofísica y la geología que estudia el campo magnético antiguo de la Tierra registrado en las rocas.

Thermal modeling is a technique used in thermocronology to reconstruct the temperature history of a rock.

Zircon, which is more resistant, registers high temperatures. Apatite, which is more sensitive to heat, registers low temperatures.

Apatite is a calcium phosphate that can be found in igneous, metamorphic, and sedimentary rocks.

Zircon is a very hard mineral that commonly forms in igneous and metamorphic rocks.

It is a thermochronological technique that makes it possible to determine when a mineral cooled to low temperatures during its geological history.
