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 antiferromagnets. These minerals have a much stronger response to the field and can have a remanence. … Meer weergeven Rock magnetism is the study of the magnetic properties of rocks, sediments and soils.
