| Abstract: | Presents research which concluded that calcite under standard conditions does not always behave as a closed system. Resolution limits of traditional geochemical techniques; Assumption that dry calcite is static and behaves as a closed system; Observations of solid-state diffusion at elevated temperatures; Evidence that monovalent ions accumulate in crystallites on the surface of calcite; Calcite's uptake capacity for contaminants. |
