    Abstract. Rock magnetism is the term commonly applied to the study of the magnetic properties of rocks and minerals, how these properties depend on factors such as grain size and shape, temperature and pressure, and the origin and characteristics of the different types of remanent magnetizations which rocks and magnetic minerals can acquire.

  • Magnetic Mineral - an overview | ScienceDirect Topics

    Magnetic minerals are ubiquitous on Earth and also on Mars, and in rocks and sediments much of the magnetic material is present in the form of small particles [30,311,312]. When igneous rocks are cooled through the Curie temperatures of the ferromagnetic or ferrimagnetic grains, they become magnetized in the direction of the Earth’s magnetic ...

  • Mineral Gallery - The Magnetic Minerals

    The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.

  • Magnetic Mineral - an overview | ScienceDirect Topics

    The magnetic minerals in various rocks can in general be separated into five main categories: (a) Diamagnetic minerals have a small negative magnetic susceptibility due to the fact that the negatively charged electrons subjected to a magnetizing field H ⇀ alter their rotation rate to oppose the field. All magnetic materials exhibit this ...
