Ground water hydraulics as a geophysical aid

The publication of the non-equilibrium formula in 1935 in a paper by Theis marked the opening of a new era in the analysis and understanding of the hydraulics of percolating ground waters. Through the past decade 9 an ever-increasing number of engineers and geologists have become familiar-with the application of this formula to practical problems of ground-water flow and have tested it in the fiel

Batholith and associated rocks of Corona, Elsinore, and San Luis Rey quadrangles southern California

The batholith of Southern and Lower California is exposed continuously from near Riverside, California, southward for a distance of about 350 miles. In central Lower California it is covered in part by younger rocks, but discontinuous bodies extend to the southern end of Lower California, and hence the batholith is probably over 1000 miles long. Its width is about 60 miles. A strip across the nort

Experimental drilling in Chattanooga shale

Information on which specifications were originally drawn for drilling the Chattanooga shale was obtained largely from the TVA, whose geologists and driller laid great stress on the difficulties of maintaining circulation in their ho;es. The stated that the shale itself was not particularly difficult to core, the trouble being in the overburden. They did not use deep casing, depending on cementi

Monazite in concentrations from Idaho placer operations

During the summer of 1947 the Atomic Energy Commission informally requested the Geological Survey collect sampled of concentrates from Idaho placer operations that might be useful for experimental study of monazite recovery. Some fourteen active gold-dredging operations were examined and sampled by Fred M. Chase during August and September 1947.
