### Discussion: Reasons for Variability in Macro Anisotropic Parameters  
The hypothesis of fluid redistribution between fracture systems of different orientations [21; 38; 102; 103] is accepted as a working hypothesis to explain variations in apparent resistivity associated with changes in the stress-strain state of geological objects. The closure or opening of fluid-filled end-to-end pore networks (cracks) leads to changes in the electromagnetic characteristics of the media, anomalous values in geophysical fields, and the appearance of rock with anisotropic properties [104]. The study of macroscale anisotropy provides a universal tool for assessing the stress-strain state of rocks at an inter-scale view considering their structural, textural, and physical properties. At the microscale level, models of telluric currents are described using Lorentz equations [66], which are then converted to [PERSON]'s equations at the macroscale. The approximation of rocks as layered bianisotropic media allows for the convenient study of macroscale parameters and transformation from one coordinate system to another. When we cross from the standard Cartesian coordinate system to any other system, the transition remains equivalent to considering gradient anisotropic media. In this case, the relationship between cross properties under EMA with effective parameters and geodynamic processes is considered. Electromagnetic monitoring enables the observation and analysis of time-dependent variations in the physicoelectric parameters of rocks. This allows for the consideration of these parameters as functions of time, leading to the transition from 3D problems, where only spatial coordinates are considered, to 4D problems, where the fourth dimension is time. The gains of the fourth dimension are temporal changes and, consequently, frequency dependence [46; 63]. This approach is essential for studying modern geodynamic processes, as the preparation of endogenous processes occurs over geological epochs. In the context of 4D problems, the observation and processing systems are considered stationary, and the results of studying physicoelectric macro-parameters are directly related to the dynamics of the observation system over time. The variability in measured physicoelectric parameters, such as apparent resistivity, is influenced by external sources outside the measurement system. Therefore, solving 4D problems requires the development of methodological foundations for geophysical monitoring and improvements to the systems used for processing multiparametric data. In the case of an arbitrary dependence in electric conductivity, which is different from the product of isolated functions of spatial coordinates in the chosen coordinate system, transitioning to another coordinate system does not allow us to obtain an electric conductivity tensor that is independent of spatial coordinates. However, it is possible to transition from a micro-inhomogeneous media to a uniformly anisotropic one if the boundaries of media contact coincide with the coordinate axis planes. The requirement that the planes of electric conductivity's discontinuity align with the coordinate planes is fundamental because it is not possible to transition from a micro-inhomogeneous model of rock structure to a homogeneous anisotropic model when switching to another coordinate system. The transition becomes more challenging for frequency-dependent parameters since it requires that the dependence of the dispersive media be expressed as a product of complex functions of a single coordinate. This idea encounters an unresolved problem at the moment. However, for one-dimensional models, it is possible to obtain effective electromagnetic parameters known as the Maxwell-Wagner effect [77; 105]. The calculations performed in this study demonstrate that structural and textural rearrangement of rocks leads to changes in the structure of all elements of the resistivity macroscale anisotropy tensor.
