International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1995
Rock magnetism is the study of induced and remanent magnetization of ferrimagnetic mineral grains in rocks, sediments, soils, and organisms. Its applications include environmental magnetism, magnetic anisotropy, sources of continental and oceanic magnetic anomalies, records of geomagnetic field variations and polarity reversals, and the paleomagnetic ...

1997
Rock Magnetism, first published in 1997, is a comprehensive treatment of fine particle magnetism and the magnetic properties of rocks. Starting from atomic magnetism and magnetostatic principles, the authors explain why domains and micromagnetic structures form in ferromagnetic crystals and how these lead to magnetic memory in the form of thermal ...

The Moon, 1972
The relationship between the magnetization and temperature in a high constant magnetic field for a temperature range between 5 K and 1100 K was examined for Apollo 11, 12 and 14 lunar materials. The average value of Curie point temperature is (768.2 ± 3.5)°C for the lunar igneous rocks and (762.5 ± 3.4)°C for the lunar fines and breccias.

The main topic of this chapter is the discussion of the natural remanent magnetization of rocks with the object of inferring the direction of the geomagnetic field in the geological past. The reader who is interested in other aspects of rock magnetism is referred to the additional references at the end.

Rock magnetism and magnetic minerals
1983Rock 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.

Abstract In any rock six kinds of magnetic anisotropy can be distinguished, viz.: (1) shape alignment of grains; (2) alignment of crystals with magneto-crystalline anisotropy; (3) alignment of magnetic domains; (4) the stringing-together of magnetic grains, which is a special case of (1); (5) stress-induced anisotropy; and (6) exchange anisotropy ...
