)[18] Magnetic remanence, recorded during the iron oxide particles, signifies the toughness of Earth's magnetic area if they had been cooled outside of their Curie temperature; this can be utilised to differentiate magnetic particles of terrestrial and meteoric origin.[19] Fly ash consists mainly of silica and calcium oxide.
