Other examples of deep-basin waters related to simple mixing of meteoric water with marine connate waters have been documented in the Dnepr-Donets basin, Ukraine (Vetshteyn et al., 1981) and the Sacramento Valley, California (Berry, 1973 Kharaka et al., 1985). Knauth (1988) used water isotopes and chemical data for waters in the Palo Duro Basin, Texas, to indicate extensive mixing between bittern brines and two...

Several of the main tributaries to the Red River (Prairie Dog Town Fork of Red River, Pease River, and their tributaries) cross outcrops of the Blaine Formation and associated strata in the southeast corner of the Texas Panhandle (Fig. 2). This area, in the eastern part of the Palo Duro Basin, embraces much of Childress, Cottle, Hall and Motley counties, Texas (Fig. 6). Salt is present at depths greater than 150—250 m below the surface (Fig. 7) in the Flowerpot, Blaine and Dog Creek formations (these three units are sometimes called the Blaine of Texas in outcrops, and they are considered part of the San Andres Formation farther west in the deep subsurface of the Palo Duro Basin). Natural dissolution of these salts in the subsurface here and farther to the west produces low- to high-salinity brines that emerge in five separate areas characterized as salt plains, seeps, or springs. These five... 

The youngest salts in the area occur in the Dog Creek Formation, where these strata are as much as 150—250 m deep in the southwest (Figs. 6 and 7). The total thickness of the salt-bearing Dog Creek sequence is typically 50— 100 m, and salt commonly appears to make up 50% of the sequence. Salts in the Dog Creek thin abruptly and are completely dissolved within a short distance in the southwestern part of the Red River study area (Fig. 7, cross-section C—B). As much as 115 m of salt-bearing strata in well 7 is represented by 65 m of non-salty equivalent strata in well 8, only 11 km to the northeast. Such abrupt thinning is not consistent with the normal pattern of nearly uniform thickness for these salt-bearing strata beneath thousands of square kilometers farther west, in deeper parts of the Palo Duro Basin.

Low concentrations of organic acids at temperatures less than 80 C occur for several reasons. One reason is the decreased organic acid generation from kerogen as a result of low thermal stress. The second reason is that dilution can occur where upward-moving acid-rich, formation waters mix with acid-poor waters of meteoric or other origins. This situation may exist in the Palo Duro Basin of west Texas (13) and the Pleistocene of offshore Louisiana (5). The third reason is that bacterial consumption of organic acids can occur at temperatures less than 80 C...
