Magnetic Anisotropy of Magmatic Rocks
Volume: 156
Series: C-12
Magnetic torque and rotational hysteresis in the field ranging from 0.01 to 0.5 T of 82 rock samples have been investigated. The rock collections consisted of basalts, dolerites, peridotites, norites, anorthosites and ores. By means of numerical analysis of their torque curves it has been stated, that the uniaxial anisotropy dominates in majority of them. In some samples of basalts and dolerites it is accompanied by the exchange anisotropy. Magnetocrystalline anisotropy of cubic minerals appears in a coarse grained dolerite samples, anorthosites and ores. Correlation analysis performed for the magnetic anisotropy and other magnetic and paleomagnetic characteristics provided evidence for some statistically significant correlations.
