The Geology and Chemistry of Natural Hot Springs

Hot springs are created when heated and pressurized groundwater is pushed up through a crack in the Earth’s surface. This water can reach temperatures up to 140°F (60°C) and contain dissolved minerals, which can provide a variety of therapeutic benefits, depending on the type of spring and the minerals it contains.

The chemistry of the spring’s water depends on several factors, such as the type of rock it passes through on its way to the surface, the elevation at which it emerges, and the climate of the area in which it is found. Most natural hot springs contain high concentrations of certain minerals, including sodium, potassium, magnesium, calcium, iron, and silica. Each of these minerals can produce different therapeutic effects on the body.
