Figure 7.32. Geochemistry of the Devonshire, Bermuda groundwater lens. (A) Well samples and location of freshwater, (B) percentage of seawater in the groundwater, (C) saturation with respect to aragonite, (D) saturation with respect to calcite. SI (= Q) is the saturation index. (After Plummer et al., 1976.)... Figure 7.32. Geochemistry of the Devonshire, Bermuda groundwater lens.

Calcium carbonate (such as calcite, siderite, dolomite, and aragonite) is typically present in marine deposits and Pleistocene sediments deposited in river-banks and practically absent in deposits from ancient rivers and deposits of Miocene age. Calcium is generally the dominant exchangeable cation (56-82%) followed by magnesium (6-26%). An important parameter for behavior during aquifer transport is the calcite saturation index (SI = log[Ca ][C03 J/KcacOj)-... [Pg.2002]
