This session will focus on the latest developments in understanding the mechanical behavior and microstructural evolution of rock salt and other evaporites. Contributions are invited on experimental, analytical, and modeling approaches that explore deformation mechanisms and the influence of petrophysical as well as microstructural features on the mechanical and hydraulic behavior of salt rocks. Particular emphasis is placed on laboratory testing methods, innovative characterization techniques, and the influence of the mineralogical-geochemical composition and impurities on mechanical performance.
