It is shown in this paper that single-domain or pseudo-single-domain magnetite grains can exist in the upper 30-45 km of the Martian crust. The upper ~50 km of the Martian crust has likely formed by volcanic eruptions on a stagnant lithosphere. A given lava flow cools very rapidly at the surface, but then is gradually heated up through burial heating as it is overlain by other successive flows. The thermal evolution models of a lava flow show that its temperature remains below the magnetic blocking temperatures of magnetite, 480-580C, until it reaches ~30-45 km depth. The highly magnetic single-domain or pseudo-single-domain magnetite grains can easily explain the strong magnetic anomalies of Mars, less than one percent by volume of magnetite particles is sufficient.
