The magnetic susceptibility of granitic rocks as a proxy ...

In paramagnetic granites, the magnetic susceptibility is a direct reflection of the mafic silicates abundance in the rock and therefore it is an accurate lithological proxy. In contrast, in most ferrimagnetic granites, the magnetic susceptibility reflects primarily the abundance of magnetite.

Magnetism - Wikipedia

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets ...

Paramagnetic Rock Dust - Secret To Healthy Plants?

What is paramagnetic rock dust?Well, let's start with paramagnetism. The soil in your organic garden is paramagnetic. It isn't magnetic, but is mildly attracted by a magnet and partially aligns with the earth's magnetic field, so it's paramagnetic. Some soils are attracted more than others, and generally, the more paramagnetic your soil is, the better.

Magnetic susceptibility of geologic materials

Bulk susceptibility of rocks depends, of course, on what magnetic minerals are present. But there is no simple relationship. For example, anisotropy is often present in metamorphic rocks, with smaller susceptibility in the direction normal to the schistosity or gneissosity than in a direction parallel to it.
