Creep Properties and Constitutive Model of Salt …

Salt deformation is the change of shape of natural salt bodies in response to forces and mechanisms that controls salt flow. Such deformation can generate large salt structures such as underground salt layers, salt diapirs or salt sheets at the surface. Strictly speaking, salt structures are formed by rock salt that is composed of pure halite (NaCl) crystal. However, most halite in nature appears in impure form, therefore rock salt usually refers to all rocks that composed mai… WebAug 7, 2024 · Halite is a useful analog for rock-forming silicates because it deforms at room temperature through a wide range of deformation mechanisms, and shows a transition from brittle to plastic deformation with increasing normal stress (e.g., Shimamoto, 1986). In this study, we demonstrate the normal stress dependence of stick-slip behavior in halite ...
