physical properties of titanomagnetite sands | geophysics

Laboratory measurements of density, magnetic susceptibility, remanence, resistivity, and induced-polarization response of New Zealand titanomagnetite sands ('ironsands') were made for different volume concentrations C V of titanomagnetite in the range 10 to 100 percent. Both density rho and magnetic susceptibility kappa of these sands increase monotonically with C V; the …

Dec 14, 2010 · Titanomagnetite contains admixtures of Al 3+, V 4+, Gr 3+, and Mn 2+. It occurs as octahedral crystals and, more frequently, granular aggregates and black masses. Hardness on Mohs’ scale is 5.0–5.5, and the density is 4,800–5,300 kg/m3. Titanomagnetites are decidedly ferrimagnetic, although ulvospinel is strictly paramagnetic
