Crustal mineralogy records the thermal history of Mars how all the planet has sheds heat and cooled over eons by erupting igneous rock
Formation
After its formation, Mars it is like all the planets in the Solar System was subjected to the so-called “Late Heavy Bombardment.

The Martian core, by contrast, is largely solid and it does not move. As a result, the planet lacks a magnetic field and is constantly bombarded by radiation.
Despite there being no magnetic field at present, there is evidence that Mars had a magnetic field at one time.
This observed paleomagnetism of minerals is found on the Martian surface it has properties that are similar to magnetic fields detected on some of Earth’s ocean floors.
