Reviews of Geophysics, 1983
I have the responsibility of reviewing the advances made in rock magnetism (and paleomagnetic data analysis) over the last four years. My charge includes the specific invitation to comment on the use of rock magnetism in the service of paleomagnetism. This is, of course, a distinction that is often difficult to draw.

Developments in rock magnetism
Reports on Progress in Physics, 1990Rock magnetism is concerned with the remanent magnetisation of ferrimagnetic fine particles in weak fields ( approximately=0.1 mT), at temperatures ranging from ambient to the Curie point, and over times of geological length. Since most magnetisations in rocks or their synthetic analogues are thermally activated, the blocking temperature below which ...

Recent advances in rock magnetism
Reviews of Geophysics, 1979It is my aim in this review article to present a personal view of the highlights in rock magnetism research in North America over the past four years. In a previous review (Banerjee, 1975), rock magnetism was presented in terms of “its applications to paleomagnetic, and hence geological and geophysical problems.” This is an extremely important aspect ...

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.

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 ...

Palaeomagnetism and rock magnetism
Earth-Science Reviews, 1966Summary The magnetic study of rocks leads to three broad fields of knowledge. The first is the history of continental movement as deduced from magnetic rocks, and the comparison of palaeomagnetically determined ancient latitudes with palaeoclimatological evidence. These areas are reviewed quite briefly. The second field is the history of the earth's

Exchange Anisotropy in Rock Magnetism
Journal of Applied Physics, 1959Some igneous rocks are magnetized in a direction opposite to that expected, if they had been cooled in the earth's magnetic field. These rocks are said to have a reverse thermo-remanent magnetization (reverse TRM). Uyeda has shown that the reverse TRM of the Haruna deposit in Japan is due to an ilmenite-hematite solid solution and has synthesized a ...

Rock magnetism—Geophysical aspects
Advances in Physics, 1955Summary This review will not be concerned with rock magnetism as a geophysical tool to assist the geologist in unravelling structures and in the correlation of strata. No doubt the remarkable development since the war of the airborne magnetometer or fluxgate and the use in consequence now made of magnetic surveys will soon need to draw upon the ...

SOME OBSERVATIONS ON ROCK MAGNETISM
GEOPHYSICS, 1958It seems that in general the plane of maximum magnetic susceptibility lies in the bedding plane for sediments and in the plane of foliation for metamorphic rocks; there is, also, a tendency for the remanent vector to lie in the plane of foliation in the latter. In the case of chemical deposits, the question is raised as to whether the hematite crystal
