https://www.pangaea.de/ information publisher tableDigital The analogue modelling of magnetic fabric in shear-zones was used to explore the time and space relationships between the finite strain and the anisotropy of magnetic susceptibility (AMS). A large shear-box was designed to enable different strain rates. The apparatus for analogue modelling of shear zones was designed in the form of a large shear box 100 cm long and 60 cm wide. In order to maintain the material complexity and to effectively realize the deformation localization coupled with an easy handling with the material, we have been working on experimental modelling using the plaster of Paris. The experiments were produced with the colored plaster of Paris with homogeneously admixed fine-grained magnetite and powder retarding the solidification reaction. Published data are from six experimental shear zones, as well as the basic simple and pure shear experiments. We publish four chosen experiments (and two additional) characterizing individual velocity range at standard displacement of 22.5 cm: fast experiments experiment #21 (6.4 cm.s-1) and experiment #25 (4.7 cm.s-1); medium velocity experiment #28 (2.7 cm.s-1) with its twin experiment #32 for reproducibility verification and slow experiment #37 (0.9 cm.s-1). Additional experiment #20 of the same speed as experiment #37 run only up to 13 cm displacement. The low field anisotropy of magnetic susceptibility was measured with the MFK1-FA Kappabridge (Jelínek and Pokorný, 1997) in the field of 423 A/m and for a F1 frequency of 976 Hz (Institute of Geophysics of the Czech Academy of Sciences). completed Kusbach, Vladimír K
