Uptake of Dissolved Fluorine from Seawater during Halmyrolysis of Igneous Rocks

According to the results of the long-term 6-year experiments, a significant decrease in the concentration of dissolved fluorine in seawater is established during its interaction with ultrabasic and basic igneous rocks: dunite, gabbro-norite, and basalt. It is concluded that submarine weathering (halmyrolysis) of rocks of the oceanic crust is a significant expense item in the geochemical balance of fluorine in the World Ocean.
