What is brine spring?

A brine spring is a type of spring that contains very high concentrations of salt. The water that emerges from a brine spring is often salty enough that it can be used for salt harvesting or for various industrial purposes. Brine springs are formed when underground salt deposits are dissolved by groundwater and the salty water is forced to the surface through pressure or the natural movement of water through the ground. The water from brine springs can be used for various purposes including salt production, as a source of salt for animal husbandry, and for the production of brine for pickling. Some brine springs are also used for medicinal purposes due to their high mineral content and perceived health benefits.
