The texture of evaporites is invariably crystalline, with grain size ranging from coarse to fine crystalline. Halite (rock salt) is found in locations where bodies of water have evaporated, such as lake beds and inland marginal seas. These minerals are not only soft, but very soluble, and thus are rarely visible in outcrop, gypsum and anhydrite being the main exceptions. The Great Salt Lake in Utah and the Dead Sea are important locations for historical non-marine evaporites, but the water there was still saline like an ocean. Other deposits are in Ohio,Kansas, New Mexico, Nova Scotia and Saskatchewan. The microscale processes that lead to creep of rock salt can be broadly separated into three categories (see review by Urai et al.
