  "definition": "A salic horizon is a horizon of accumulation of salts that are more soluble than gypsum in cold water. A common salt is halite, the crystalline form of sodium chloride. In some areas soluble sulfates may also accumulate with the crystalline forms, such as thernadite, hexahydrite, epsomite, and mirabilite. Two of the commonly occurring bicarbonates are trona and natron. Under extreme aridic conditions and at low temperatures, evaporites of calcium chloride, nitrates, and other soluble salts may accumulate. Identification of the kinds of crystalline salts requires detailed mineralogical analyses.",
