MAGNETIC SUSCEPTIBILITY LOGGING FOR CORES

In sedimentary environments, magnetic susceptibility is directly proportional to the magnetic mineral content of sediments, so it can be used as a non destructive, first order assessment of the concentration of iron bearing magnetic minerals.

Magnetic Susceptibility Mining Fundamentals

Magnetic susceptibility is a measure of the ability of a substance to be magnetized in the presence of an external magnetic field. In principle, magnetic susceptibility measurement is based on the amount and type of magnetic minerals within the rocks.

In electromagnetism, the magnetic susceptibility (Latin susceptibilis, "receptive"; denoted ) is one measure of the magnetic properties of a material. The susceptibility indicates whether a material is attracted into or repelled out of a magnetic field, which in turn has implications for practical applications.

The anisotropy of magnetic susceptibility of some igneous

The anisotropy of magnetic susceptibility of some basic igneous and metamorphic rocks has been found to be due to the preferred orientation of the long axes of grains of magnetite. The degree of anisotropy is in a few samples as great as 40 per cent but usually is less than 10 per cent.

Bulk susceptibility of rocks depends, of course, on what magnetic minerals are present. But there is no simple relationship. For example, anisotropy is often present in metamorphic rocks, with smaller susceptibility in the direction normal to the schistosity or gneissosity than in a direction parallel to it.

A high sedimentary rate will dilute the magnetic minerals in the atoll facies and the high water agitation during deposition may be expected to have prevented the deposition of the magnetic grains. So, the combination of these two effects will result in the observed low values in the atoll crown and lagoonal facies. Magnetic susceptibility

Magnetic susceptibility (MS) is a property of sediments, including cave sediments, that can be measured and, under the proper circumstances, is indicative of paleoclimate. MS is not to be confused with remanent magnetism, the intrinsic magnetization that accounts for the magnetic polarity record contained in some materials.
