Halite creep
WebSingle crystals of pure and impure halite have been dynamically recrystallized during compression creep at temperatures between 250° and 790°C and stresses between 1.5 and 120 bars. WebSince it forms primarily from evaporation, halite normally is found with other evaporation-associated minerals such as calcite, gypsum, anhydrite, and sylvite. Sylvite, although rare, is poisonous - so it is a good idea to use your finger to test an unknown sample’s taste, rather than directly licking the sample.

WebJun 26, 2016 · Abstract: Creep plays an important role in mine design and ground control for potash solution mining. In order to predict the temporal evolution of underground caverns during and after solution mining, the long-term creep behavior of sylvinite and halite, i.e., secondary or steady-state creep rate, must be known. To date, however, only limited … WebJan 3, 2008 · At depth of 100 m, the halite is tight, entirely cemented and has no measurable permeability. The very low permeability of halite is demonstrated by …
WebSep 1, 2008 · Rock salt (halite), which usually constitutes the main volumetric proportion of a mobilized evaporitic succession (Jackson and Hudec, 2024), deforms by a 170 combination of dislocation and... 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…
