|Cape Fear Formation, South Carolina Coastal Plain
The Cape Fear Formation contains substantial volumes of clays and labile minerals that can potentially react with ground water (Gohn and others, 1977). Miller and others (1986) provided an excellent discussion of sediment/water interaction as a function of ground-water residence time in southeastern U.S. coastal plain aquifers. For the GIS we used information from Miller and others (1986) to characterize rock/water reactions that can be expected in the Cape Fear hydrostratigraphic interval. Immature sands may have moderate potential for interaction with high-CO2 fluids.
