- Аннотация: According to widespread concepts of tectonophysics, the problem of retrieving the stress tensor T from the fault-slip data is routine and solved locally for a block of the Earth's crust without taking into account its interaction with adjacent blocks. This contradicts mechanics where stress from kinematics in micro- and/or meso-scale can be determined locally only for an isolated volume. If the block is an open system, exchanging momentum and angular momentum with the environment, then we can talk about the construction of constitutive relations, rather than about the stress determination. The stress is determined by integrating the equilibrium equations. On top of that, in tectonophysics stress is thought to be the only cause of the observed kinematics. The paper presented discusses these and other fundamental misconceptions of the tectonophysical approach to stress reconstruction.
