Title – Use of magnetic susceptibility in characterization of geological materials. Case studies


Abstract – The use of magnetic susceptibility in characterization of geological materials can be used in a wide range of applications for various reasons: (i) applicability to practically all types of materials, rocks, soils, sediments and leaves of trees; (ii) possibility of identifying the magnetic mineral and/ or magnetic particle size; (iii) possibility of identifying the material provenance and (iv) is a low-cost technique. In this talk physical principles of this technique, magnetic mineralogy and magnetic particles and sampling and lab procedures will be given. Case studies involving environmental magnetism, geological applications and magnetism in biosphere will be presented.
