  • Magnetic Mineral - an overview | ScienceDirect Topics

    Magnetic minerals are ubiquitous on Earth and also on Mars, and in rocks and sediments much of the magnetic material is present in the form of small particles [30,311,312]. When igneous rocks are cooled through the Curie temperatures of the ferromagnetic or ferrimagnetic grains, they become magnetized in the direction of the Earth’s magnetic field.
