 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.The brine cropping out at the surface as saltwater springs are known as "licks" or "salines".The contents of dissolved solids in groundwater vary highly from one location to another on Earth, both in terms of specific constituents (e.g.
