Uptake of Dissolved Fluorine by Carbonate Minerals From Seawater

A 9-year experiment studying the uptake of dissolved fluorine by calcite, aragonite, and dolomite from seawater was shown that the presence of magnesium in sedimentary carbonate minerals promotes the fluorine accumulation in them. By intensity of the dissolved fluorine removal from seawater, carbonate minerals are arranged in the following order: dolomite calcite aragonite and the fluorine uptake by dolomite is 40–60 times higher than by calcite and aragonite. It was concluded that the magnetality of sedimentary carbonate rocks is an important factor controlling their fluorine content, along with the fluorine concentration in the waters of sedimentation basins.
