Deep‐seated solution in the Meade basin and vicinity, Kansas and Oklahoma

During the closing years of the 19th century, Haworth [see 1 and 2 of “References” at end of paper] and Johnson [3] noted the abundant depressions resembling sink‐holes in the Southern High Plains, especially in Meade and Clark counties, Kansas, and Beaver County, Oklahoma. Johnson was of the opinion that all the depressions and basins in this region were due to solution, whereas Haworth [1] believed the Meade artesian basin to be structural, although he held to a solutional origin for the Ashland and Englewood basins, which are a few miles to the east. ©1942.

Chemistry and movement of ground water, Nevada Test Site

Three chemical types of ground water are distinguished at the Nevada Test Site and vicinity. A sodium-potassium water is related to tuff (in part zeolitized) and to alluvium containing detrital tuff. A calcium-magnesium water is related to limestone and dolomite, or to alluvium containing detritus of these rock types. A mixed chemical type, containing about as much sodium and potassium as calcium and magnesium, may result from the addition of one of the first two types of water to the other; to passage of water first through tuff and then through carbonate rock, or vice versa; and to ion-exchange during water travel. Consideration of the distribution of these water types, together with the distribution of sodium in the water and progressive changes in the dissolved solids, suggests that the ground water in the Nevada Test Site probably moves toward the Amargosa Desert, not into Indian Spring Valley and thence southeastward toward Las Vegas. The low dissolved solids content of ground-water reservoirs in alluvium and tuff of the enclosed basins indicates that recharge is local in origin.

Ground water in alluvial deposits in Oklahoma

Alluvium along main streams in Oklahoma has long been recognized as a generally dependable aquifer. Pumping tests made in recent years afford a means of comparing one area with another. They indicate coefficients of transmissibility on the order of 70,000 gallons per day per foot in the Arkansas River alluvium near Fort Gibson, and 60,000 in the North Canadian River alluvium near Oklahoma City and El Reno.

Geology of the Cedar Hills, Utah

The Cedar Hills, an area of about 320 square miles in central Utah between the northern end of the Wasatch Plateau and the southern end of the Wasatch Mountains, form the boundary zone between the Colorado plateaus and the Great Basin. The oldest exposed rocks are Carboniferous, but most of the area is underlain by Upper Cretaceous and Tertiary continental sediments many thousands of feet thick. The Indianola group, about 15,000 feet thick, consists principally of coarse conglomerates and sandstones indicative of near-by orogeny and contains a tongue of fossiliferous marine sandstones showing that it is of Colorado age. This group is overlain unconformably by thick fluviatile and lacustrine deposits ranging from Montana to Eocene in age (Price River, North Horn, Flagstaff, Colton, and Green River formations), which in turn are overlain unconformably by probably late Tertiary pyroclastics. The area was subjected to come pressive orogenic disturbances in middle Cretaceous, upper Cretaceous (Montana), and probably middle Tertiary time, and to the normal faulting of the Basin-Range disturbance in late Tertiary time. © 1951, The Geological Society of America, Inc.

Ground water in the Oklahoma Panhandle

An investigation begun in 1937 by the United States and the Oklahoma Geological Surveys, has shown that the depth to the water table in the Oklahoma Panhandle ranges from less than 25 feet in parts of major valleys to about 3oo feet in parts of the uplands. In 8 upland areas the depth is between 50 and 100 feet. The thi kness of the zone of saturation differs widely in these areas, the most promising of which totals about 80 square miles in northeastern Texas County. The pervious sands and gravels of the Ogallala formation, of Pliocene age, furnish most of the ground water, and one well yielding 960 gallons a minute from them has been used for irrigation since x937. The formation ranges from less than xoo to more than 500 feet thick, the differences being due to relief on the pre-Ogallala topography and to post-Ogallala erosion. The alluvium is also an important source of water, as are the Dakota and Cheyenne sandstones, of Cretaceous age. A few wells yield water of variable quality from Jurassic and Triassic rocks, and many wells in the valleys of the eastern part of the area yield small supplies of highly mineralized water from Permian red beds. © 1940 Society of Economic Geologists, Inc
