Magnetic Anisotropy Fabrics and Deformation: New Approacheswith Synthetic and Natural Samples

磁化率各向异性的应用 尽管对岩石变形的研究一直令人失望， 其明显的潜力。 这种方法的局限性是由于 （1）不完全或没有表征主导磁场 （2）不完全或没有分离的贡献， 铁（O）-和顺磁性矿物。 本方法 通过（1）仔细的光学研究和（2）克服这些限制 测量磁组构成分的新方法。 完成 磁性矿物学和结构表征 关系是该项目的一个关键因素，将 使用光学（透射和反射）进行， （分析）电子显微镜（SEM，微探针），各向异性 剩磁（pARMA）和低温磁化率。

The application of anisotropy of magnetic susceptibility (AMS) to the study of rock deformation has been disappointing is spite of its apparent potential. The limitations of this method are due to (1) incomplete or no characterization of the dominant magnetic phases and (2) incomplete or no separation of the contribution of ferri(o)- and paramagnetic minerals. The present approach overcomes these limitations by (1) careful optical studies and (2) new methods to measure components of the magnetic fabric. Complete characterization of the magnetic mineralogy and textural relationships is a crucial element of the project and will be carried out using optical (transmitted and reflected) and (analytical) electron microscopy (SEM, microprobe), anisotropy of magnetic remanence (pARMA) and low-temperature susceptibility.
