Journal ArticleDOI
Rock magnetism and the interpretation of anisotropy of magnetic susceptibility
TL;DR: The conventional rules for the interpretation of magnetic susceptibility (AMS) in terms of microstructure and deformation are subject to numerous exceptions as a result of particular rock magnetic effects.
Journal ArticleDOI
Tectonic applications of magnetic susceptibility and its anisotropy
TL;DR: In this article, the shape of the AMS ellipsoid combines contributions from several different types of AMS components, and the shape changes with the proportions of the different components.
Journal ArticleDOI
Magnetic susceptibility, petrofabrics and strain
TL;DR: Magnetic susceptibility is a non-destructive technique for quantifying the average fabric of a small sample of rock as mentioned in this paper, which is not routine substitute for strain analysis, however, the interpretation of the magnetic fabric is not always straightforward and the principal directions of the magnitude ellipsoid of susceptibility commonly show orientations consistent with the kinematic interpretations of folds, shear zones and other structural features.
Journal ArticleDOI
Anisotropy of magnetic susceptibility (AMS): magnetic petrofabrics of deformed rocks
TL;DR: In this paper, the main factors determining the magnetic fabrics of tectonized rocks include mineral-physics properties, crystal symmetry, mineral abundance, mineral-abundances, tectonic symmetry and crystal orientation-distribution, strain or stress, kinematic history and certain tectono-metamorphic processes (e.g., diffusion, crystal plasticity, dynamic recrystallization, particulate flow, neomineralization).
Journal ArticleDOI
Anisotropy of magnetic remanence: A brief review of mineralogical sources, physical origins, and geological applications, and comparison with susceptibility anisotropy
TL;DR: In the absence of a magnetic field, the magnetic fabric of rocks and sediments is most commonly characterized in terms of the anisotropy of low-field magnetic susceptibility (AMS) as mentioned in this paper.

Magnetic anisotropy of rocks and its application in geology and geophysics
TL;DR: Magnetic anisotropy in sedimentary rocks is controlled by the processes of deposition and compaction, in volcanic rocks by the lava flow and in metamorphic and plutonic rocks by ductile deformation and mimetic crystallization as discussed by the authors.

Magnetic, seismic, and other anisotropic properties of rock fabrics
W. H. Owens,D. Bamford +1 more
TL;DR: In this paper, the usefulness of magnetic and seismic anisotropy in fabric studies is investigated. But the authors focus on the magnetic anisotropic properties of fabric and do not consider the seismic properties.

The effect of quartz on the magnetic anisotropy of quartzite
František Hrouda,Aleš Kapička +1 more
TL;DR: The magnetic susceptibility of quartz single crystals is diamagnetic (−14×10−6 in SI units) and exhibits only very small anisotropy (mostly less than 1%); thus the susceptibility of the quartz matrix in quartzite can be regarded as virtually isotropic as mentioned in this paper.
Journal ArticleDOI
Iron-titanium oxide minerals, rocks, and aeromagnetic anomalies of the Adirondack area, New York
TL;DR: In this paper, it was shown that the reverse magnetization of rocks is caused by a reversal of the earth9s magnetic field at the time they cooled through the Curie point.

The development of magnetic susceptibility anisotropy through crystallographic preferred orientation in a calcite rock
TL;DR: In this paper, high-field torque-meter measurements of diamagnetic susceptibility anisotropy of a suite of samples of Carrara marble, axially shortened by amounts up to 50% at (1.5-3.0) · 10 8 Pa confining pressure and at 20-500°C (mainly 400°C), have been compared with optical measurements of preferred crystallographic orientation.
