...(aq) . Subsequently, bismutite I was replaced by bismutite II and kettnerite. The former requires an influx of Ca and F and its formation can be characterized by the reaction Bi 2 CO 3 O 2(s) + 2Ca 2+ (aq) + 2F – (aq) + CO 3 2– (aq) = 2CaBiCO 3 OF (s) . At the late hydrothermal stages bismutite...
