Notes:
Sodium-chloride brine underlies the shallow subsurface and discharges at numerous surface locations in the Rolling Plains of north-central Texas. According to the ratios of Na/Cl and Br/Cl, and supported by the contribution of other chemical constituents, two major brine types can be distinguished: (1) brine derived from dissolution of halite by fresh ground water, and (2) brine derived from discharge of deep-basin brine aquifers. All salt-spring brines as well as shallow subsurface brines in the northern and western parts of the Rolling Plains represent halite-dissolution brine, whereas deep-basin brine is represented by samples in the shallow subsurface in the south.The oxygen and hydrogen isotopic composition of the halite-dissolution brines indicates a local, meteoric origin for these brines. Shallow subsurface samples from the southeastern Rolling Plains graphically include deep-basin brine values and meteoric-water values as end points, suggesting mixing of deep-basin brine with local meteoric ground water.
