Magnetic properties of marine limestones Lowrie

The magnetic mineralogy of a limestone is difficult to describe optically because of the small grain size and low concentration; magnetic techniques are more convenient. Direct analysis of extracted magnetic minerals is handicapped by the difficulty of obtaining a representative extract.

Siderite formation in anoxic deep-sea sediments: A

These daughter products can completely change the magnetic properties of limestone samples and if unrecognized may be one of the primary reasons why many paleomagnetic studies of limestones, especially Paleozoic limestones, are unsuccessful. Second, siderite in weakly magnetized rocks may indicate the potential for successful paleomagnetic results.

Nuclear Magnetic Resonance relies on a simple principle that the molecular behaviour of materials can be affected by a magnetic field [1]. The best model for describing this behaviour is to consider nuclei as bar magnets. In order to be able to align certain nuclei with magnetic properties in a magnetic field [1].
