Strontium in sedimentary rocks

Elemental strontium has a strong affinity for limestone-dolostone. Its distribution in these sedimentary rocks is controlled mainly by the extent Sr 2+ may substitute for Ca 2+ in the CaCO 3 lattice, or by the presence of strontium-forming minerals such as celestite and strontianite. Substitution may follow diadochic (direct), adsorption, and occlusion …
