Viking mission soil analyses and the constitution of the SNC group of meteorites have indicated that the Martian regolith is derived from basalt. On earth such material often weathers to yield a highly magnetic soil (spontaneous magnetization sigma/s/ not less than 1 J/T per kg), the magnetic constituent of which is fully oxidized titanomaghemite. It is proposed that titanomaghemite is likewise responsible for the magnetism of the soils on Mars.
