The anisotropy of magnetic susceptibility of some

The anisotropy of magnetic susceptibility of some basic igneous and metamorphic rocks has been found to be due to the preferred orientation of the long axes of grains of magnetite The degree of anisotropy is in a few samples as great as 40 per cent but usually is less than 10 per cent The variation in anisotropy is believed to be due to
