Abstract Magnetic fabrics are used extensively as proxies for mineral fabrics and to correct paleomagnetic data, and have been proposed to quantify pore fabrics. Today's understanding and interpretation of magnetic anisotropy benefits from decades of carefully observing anisotropic mineral and rock properties, establishing and testing empirical relationships between magnetic and mineral fabrics, and developing models to quantify aspects of anisotropy. Each advance was preceded by some puzzling observations, i.e., data that could not be explained based on the models available at the time, e.g., ‘oblique’ or ‘inverse’ fabrics, or lithology-dependent anisotropy-strain relationships. These observations led to numerous experimental and numerical techniques designed to characterize magnetic fabrics and determine their origin. Despite the successful application of magnetic fabrics in many structural and tectonic problems, there are still phenomena and measurements that cannot be explained based on today's magnetic fabric theory. With the purpose of fostering future development, I will touch on three main areas where I see challenges in magnetic fabric research: (1) Experimental characterization of magnetic anisotropy, including the non-uniqueness of reported tensors, and non-linearity; (2) anisotropy modelling and defining the carrier minerals and origin of the magnetic fabric; (3) selection of adequate (sets of) anisotropy tensors to correct paleomagnetic data. The description of the challenges presented here will hopefully help define directions for future research, inform those that are new to anisotropy, and advance our field.

磁性织物研究的当前挑战和未来发展

摘要 磁性织物被广泛用作矿物织物的替代物和校正古地磁数据，并已被提议用于量化孔隙织物。今天对磁各向异性的理解和解释得益于数十年来对各向异性矿物和岩石特性的仔细观察，建立和测试磁性和矿物结构之间的经验关系，以及开发量化各向异性方面的模型。每次取得进展之前都有一些令人费解的观察结果，即无法根据当时可用的模型解释的数据，例如“倾斜”或“反向”织物，或依赖于岩性的各向异性-应变关系。这些观察导致了许多旨在表征磁性织物并确定其起源的实验和数值技术。尽管磁性织物在许多结构和构造问题中得到了成功应用，但仍然存在基于当今磁性织物理论无法解释的现象和测量。为了促进未来的发展，我将谈及我认为磁性织物研究中存在挑战的三个主要领域：（1）磁各向异性的实验表征，包括报告张量的非唯一性和非线性；(2) 各向异性建模和定义磁性织物的载体矿物和来源；(3) 选择足够的（组）各向异性张量来校正古地磁数据。对这里提出的挑战的描述有望帮助确定未来研究的方向，为那些对各向异性不熟悉的人提供信息，并推进我们的领域。
