Sulphate minerals of the Comstock Lode, Nevada
C. Milton, W. D. Johnston Jr.
1938, Economic Geology (33) 749-771
Seventeen representative samples of supergene sulphates from old workings on the Comstock Lode are described. They range from simple minerals such as gypsum and epsomite to complex aggregates of four or more distinct species. All are well known species except a mineral of the copper (chalcanthite) or magnesium sulphate pentahydrate...
Thermal springs in the United States
Norah D. Stearns, Harold T. Stearns, Gerald A. Waring
1937, Water Supply Paper 679-B
The earliest extensive studies of thermal springs in the United States were made by physicians. In 1831 Dr. John Bell issued a book entitled "Baths and Mineral Waters" in which he listed 21 spring localities. In the edition of his work published in 1855 the number was increased to 181....
Ground water in Creek County, Oklahoma
Richard Carlysle Cady
1937, Open-File Report 37-2
Creek County has been designated as a problem area by the Land Use Planning Section of the Resettlement Administration. Some of the earliest oil fields to brought into production were situated in and near this county, and new fields have been opened from time to time during the ensuing years....
Isometric block diagrams in mining geology
W. D. Johnston Jr., Thomas B. Nolan
1937, Economic Geology (32) 550-569
In the past five years members of the Geological Survey have gained experience in making isometric block diagrams of mines and mining districts as well as of surface features. This paper presents nothing new, but aims to assemble scattered information on a much neglected method of geological illustration. Plotting mine...
The Battle Branch gold mine, Auraria, Georgia
Charles Frederick Park, R.A. Wilson
1936, Economic Geology (31) 73-92
The Battle Branch mine, in north-central Georgia, is well known locally for its pockets of exceptionally rich gold ore. During the period from May 24, 1934, to May 20, 1935, 781.97 ounces of bullion, of an average fineness of about 850, was shipped to the mint. The deposit is of...
The McCoy mining district and gold veins in Horse Canyon, Lander County, Nevada
Frank Charles Schrader
1934, Circular 10
The following geologic sketch is based on a two-day visit made to the McCoy district in September 1930. For valuable information and aid generously extended, the writer would express his thanks to the miners and prospectors of the district and especially to Mr. Joseph H. McCoy, a well-known mining man...
Determination of the common and rare alkalies in mineral analysis
R. C. Wells, R.E. Stevens
1934, Industrial And Engineering Chemistry Analytical Edition (6) 439-442
Methods are described which afford a determination of each member of the alkali group and are successful in dealing with the quantities of the rare alkalies found in rocks and minerals. The procedures are relatively rapid and based chiefly on the use of chloroplatinic acid, absolute alcohol and ether, and...
Deep‐well salinity‐exploration
A.G. Fiedler
1933, Eos, Transactions, American Geophysical Union (14) 478-480
One of the outstanding accomplishments of recent years in connection with the study of the geologic source of groundwater and the quality of water yielded by different formations has been the development of methods and equipment for the exploration of wells. The description and use of the deep‐well current‐meter on well‐exploration work in Hawaii and New...
Ground water supplies of the Camden area, New Jersey
David G. Thompson
1932, Report
This report is one of several setting forth the results of investigations as to the safe yield of the principal water-bearing formations in certain parts of New Jersey, carried on cooperatively by the New Jersey Department of Conservation and Development and the United States Geological Survey. Other areas in which...
Physiography and Quaternary geology of the San Juan Mountains, Colorado
Wallace W. Atwood, Kirtley F. Mather
1932, Professional Paper 166
The scenic beauty, rugged contour, and great variety of geologic phenomena displayed by the San Juan Mountains of southwestern Colorado have lured to that region many geologists, both professional and amateur, as well as countless laymen. Serious geologic studies in these mountains seem to fall historically into three periods. The first...
Mineralogy of drill cores from the potash field of New Mexico and Texas
Waldemar Theodore Schaller, Edward Porter Henderson
1932, Bulletin 833
The potash field of southeastern New Mexico and adjacent parts of Texas is confined to the southern part of the Permian salt basin, covering about 40,000 square miles. The potash and associated minerals lie in a body of Permian halite, whose top is at least several hundred feet below the...
A preliminary report on the artesian water supply of Memphis, Tennessee
F. G. Wells
1932, Water Supply Paper 638-A
Memphis is located in the part of the Gulf Coastal Plain known as the Mississippi embayment. It is underlain by unconsolidated sand and clay formations of Tertiary and Cretaceous age. The Wilcox group, of Tertiary age, and the Ripley formation, of Cretaceous age, are excellent aquifers, and all the water...
Geology of the De Queen and Caddo Gap quadrangles, Arkansas
Hugh D. Miser, Albert Homer Purdue
1929, Bulletin 808
The field study of the geology of the De Queen and Caddo Gap quadrangles extended over a period of many years, and although the scientific and economic results from the study are here set forth fully for the first time in a single report, a number of publications have been...
The brown iron ores of west-middle Tennessee
E. F. Burchard
1927, Bulletin 795-D
A study of the brown iron ore deposits of west-middle Tennessee has been carried on recently under a cooperative agreement between the Tennessee State Geological Survey and the United States Geological Survey. A detailed report on the subject was submitted in the spring of 1925 to the State Survey for...
The divining rod: A history of water witching, with a bibliography
Arthur Jackson Ellis
1917, Water Supply Paper 416
The use of a forked twig, or so-called divining rod, in locating minerals, finding hidden treasure, or detecting criminals is a curious superstition that has been a subject of discussion since the middle of the sixteenth century and still has a strong hold on the popular mind, even in this...
