Using a non-magnetic pressure cell, we carried out hydrostatic pressure demagnetization experiments up to 1.2 GPa on samples of meteorites and terrestrial rocks of different lithologies and on synthetic samples of dispersed powders of magnetite, hematite, pyrrhotite and iron. In these experiments A wide spectrum of different mineralogies (about 50 samples) was investigated to have a clearer picture of their pressure demagnetization behavior: pyrrhotite-, titanomagnetite- and FeNi-bearing meteorites; magnetite- and titanomagnetite-bearing terrestrial igneous rocks; and a variety of pyrrhotite-, hematite-, goethite- and greigite-bearing rocks. Under 1.2 GPa, these samples lost between 0 and 70% of their original saturation isothermal remanent magnetization. Although pressure demagnetization varies from one mineralogical group to the other, within each group the demagnetization at 1.2 GPa is a linear function of logBcr (coercivity of remanence).
