Abstract: Spatiotemporal distributions of local components of the distortion tensor of quasi-plastic materials–saliferous rocks (sylvinite)–have been studied under active compressive straining conditions using double-exposure speckle photography techniques. The strain localization patterns are presented and the features of macroscopic strain inhomogeneity are considered for inelastic behavior of the material. Results obtained for the slow wave processes in deformed saliferous rocks are compared to analogous data available for ionic crystals.
