Abstract—

A nine-year experimental study of the uptake of dissolved fluorine by calcite, aragonite, and dolomite from seawater has shown that the occurrence of magnesium in sedimentary carbonate minerals is favorable for their enrichment in fluorine. According to the intensity of dissolved fluorine removal from seawater by carbonate minerals, these minerals are arranged in the following succession: dolomite \( \gg \) calcite > aragonite, and the fluorine uptake by dolomite is 40–60 times higher than by calcite and aragonite. It was concluded that the magnesiality of sedimentary carbonate rocks is an important factor controlling their fluorine content, along with the fluorine concentration in the waters of the sedimentation basins.
