It has been determined that the content of dissolved fluorides in waters of 13 mud volcanoes of the Kerch-Taman Region varies within 0.13–2.00 mg/L and averages 0.87 mg/L (n = 37). We have revealed a rather close correlation of the fluorine concentration with pH (r = 0.80) and the absence of its relationship with the mineralization and the content of components of the basic salt composition. It is suggested that the fluorine concentration in mud-volcano waters is controlled by the exchange reaction + OH– = F– + , where and are the contents of adsorbed and structural fluorine (hydroxyl ions) in clay minerals, and F– and OH– are the concentrations of fluorides (hydroxyl ions) in the water phase.
