Magnetic mineralogy - Wikipedia

Magnetic mineralogy is the study of the magnetic properties of minerals. The contribution of a mineral to the total magnetism of a rock depends strongly on the type of magnetic order or disorder. Magnetically disordered minerals (diamagnets and paramagnets) contribute a weak magnetism and have no remanence. The more important minerals for rock magnetism are the minerals that can be magnetically ordered, at least at some temperatures. These are the ferromagnets, ferrimagnets and certain kinds of antiferromagn

Techniques for Collectors : List of magnetic minerals

Apr 15, 2019  Having the magnetic character of a mineral listed among the properties would be helpful. I hung two neodymium magnets (about 3 x 5 x 1 cm each) from a 27 cm length of video-tape and stuck a 1 cm square mirror to it. Shining a bright light on the mirror, I had an optical lever that would detect magnetism in all ferromagnetic and most ...

Magnetic and Gravity Methods in Mineral Exploration: the ...

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
