in a solution of brine called evaporite in geologic deposits, what is the salt?
halite, anhydrite, carbonates, gypsum, fluoride-salts, organic halides, and sulfate-salts
numerous processes exist which can produce brines in nature. modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit called an evaporite is formed as different dissolved ions reach the saturation states of minerals, typically gypsum and halite. a similar process occurs at high latitudes as seawater freezes resulting in a fluid termed a cryogenic brine. at the time of formation, these cryogenic brines are by definition cooler than the freezing temperature of seawater and can produce a feature called a brinicle where cool brines descend, freezing the surrounding seawater.
brine
salt is made in two ways traditionally. rock salt is mined from the ground. the other type known as white salt is made by the evaporation of brine. brine is obtained in several ways. wild brine streams, occurring from the natural solution of rock salt by ground water, can come to the surface as natural brine springs or can be pumped up to the surface at well, shafts or boreholes. artificial brine is obtained through solution mining of rock salt with fresh water and is known as ‘controlled brine pumping’. a bastard brine used to be made by allowing fresh water to run through abandoned rock salt mines. a salt-on-salt process strengthens brine by dissolving rock salt, and/ or, crystal salt in weak brine or sea water prior to evaporation. solar evaporation uses the sun to strengthen and evaporate sea water trapped on the sea-shore to make sea salt crystals, or to strengthen and evaporate brine sourced from natural springs where it is made into white salt crystals.
