Modelling the magnetic properties of natural and environmental materials
Magnetic properties have been used to characterize natural and environmental materials. An evaluation of magnetic properties, for the modelling of sources of materials and minerals, has been completed. A methodological framework has been developed for the application of magnetic techniques to studies involving the quantification of sources of materials and minerals in any environment. the framework includes the idntification of sources using magnetic reconnaissance and multi-variate statistical classification techniques. magnetic measurements used are susceptibility (both field and laboratory), remanence and magnetization measurements. the linear additivity of magnetic measurements, and classification and linear modelling techniques, ahve been tested using datea for artificial laboratory mixtures and hypothetical mixing experimentrs. The limitations of using magnetic properties with these statistical and mathematical techniques are defined. the famework allows for hte testing of suitabililty of manetic modelling techniques in any sourceing study.
