RS is the ratio of calcite activity product (Ka) to calcite solubility product (Ksp), SI value of less than 1 indicates undersaturation, SI of 1 indicates saturation, and SI of more than 1 indicates supersaturation.
Carbonate reservoirs and factors affecting calcium carbonate (limestone) dissolution
Simultaneously with the decrease in the influx of carbonate products by surface and subsurface waters as a result of considerable lixiviation of till layers, carbonate balance in lake water was disturbed: oversaturation was replaced by undersaturation and the stage of Si[O.sub.2] prevalence in the ashy part of bottom deposits and formation of organic-mineral gyttja began.

Mixing of groundwaters may lead to pronounced undersaturation or supersaturation with respect to carbonate minerals, depending on temperature, pressure, and fluid composition, particularly pC[O.sub.2] of the mixed water.

The undersaturated DO concentrations at the Oligohaline site indicate that respiration outweighs production (as was found by Durand and Nadeau, 1972), although it is possible that groundwater of low DO contributed to this undersaturation.
