Anisotropy of remanent and induced magnetization was found to be compositionally controlled in synthetic samples of varying proportions of chlorite (a platy paramagnet), manganese oxide (an isotropic paramagnet), and magnetite (an anisotropic ferrimagnet). Grains were magnetically aligned in a 100 mT field, then uniaxially compressed at 27.6 MPa to produce an L-S fabric. Anisotropy of anhysteretic susceptibility (AAS) and anisotropy of magnetic low-field susceptibility (AMS) are coaxial, and anhysteretic susceptibility is consistently more anisotropic than low-field susceptibility. AMS increases with the addition of oblate magnetite, but decreases with addition of isotropic Mn2O3 to chlorite. These experiments demonstrate that magnetic anisotropy depends on the shape, relative magnetic intensity, and proportion of the magnetic minerals. ¿American Geophysical Union 1991
