Geochemistry of sedimentary basin formation water

Pore water in sedimentary basins reflects long-period water-rock interaction, with initial solutions being either buried seawater or halite-dissolution water. The Gulf Coast sedimentary basin contains three major types of water: relatively low-salinity Na-acetate rich water, Na-Ca-Cl water, and Na-Cl water. These fluids occupy distinct positions in the stack of sediments that fill in the basin, and the trace elements associated with these waters reflect different degrees and types of chemical reactions with host sediments.
