EMRP3.5Anisotropy of Magnetic Susceptibility: recent advances and novel applications
|Co-Convener: Fátima Martín-Hernández
Anisotropy of Magnetic Susceptibility (AMS) has emerged as a powerful and rapid technique in quantitatively evaluating the petrofabric of geological materials. Most rock-forming minerals are magnetically anisotropic because the crystallographic and/or shape preferred orientation controls the easy magnetization along preferred directions. This in turn facilitates measurement of the fabric of a given rock sample. Almost six decades have past since the application of magnetic anisotropy as a petrofabric tool was first employed. Magnetic anisotropy is now being used to tackle a broad spectrum of geological and geographical problems and advanced rock magnetic techniques such as anhysteretic remanent magnetization and low temperature AMS complement standard AMS datasets. This session aims to integrate applications of magnetic anisotropy in diverse geological issues including, but not restricted to, granite emplacement, layered mafic-ultramafic intrusions, fold and thrust belts, ophiolites, lithified and non-lithified sediments, mylonites, glacial moraines and also discuss recent technical advances in this technique.
