Processes Governing Alkaline Groundwater Chemistry within a Fractured Rock (Ophiolitic Mélange) Aquifer Underlying a Seasonally Inhabited Headwater Area in the Aladağlar Range (Adana, Turkey)

Table 5

Results of PHREEQC [78] inverse geochemical models related to representative end-member water types (i.e., precipitation (snow), dry season groundwater, and wet season groundwater; see Table 3) of the Kızılgedik site (Adana, Turkey) showing the mass transfer of reactants and products. Values are in moles per kilogram H₂O (positive values indicate dissolution or ingassing and negative values indicate precipitation or outgassing).

Dashes indicate phase not used in model. Reactants start with O₂ (g) and end with halite. The rest of the mineral phases belong to products (from dolomite to CrO₃).
