Mercury in the United States, exclusive of Alaska and Hawaii
Edgar Herbert Bailey
1962, Mineral Investigations Resource Map 30
This map shows the location of mercury districts and deposits in the United States (exclusive of Alaska and Hawaii). The map was compiled from published reports and from data in the files of the Geological Survey. All map locations are numbered consecutively in each state and names, geographic coordinates, and...
Bismuth in the United States, exclusive of Alaska and Hawaii
John Roberts Cooper
1962, Mineral Investigations Resource Map 22
The bismuth-bearing deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map the deposits were classified into two categories: 1) those that have produced bismuth or are regarded as potential sources based on available information (in general, this category includes...
Titanium in the United States, exclusive of Alaska and Hawaii
Cleaves Lincoln Rogers, Marion Charlotte Jaster
1962, Mineral Investigations Resource Map 29
The accompanying map shows the location of the principal deposits of titanium minerals in the United States (excluding Alaska and Hawaii). Four broad geologic categories of deposits have been distinguished on the map by the shapes of the symbols, and relative importance is indicated by their size. The smaller deposits...
Floods of February 1962 in southern Idaho and northeastern Nevada
Cecil Albert Thomas, Robert D. Lamke
1962, Circular 467
The floods of February 10-15, 1969., were the highest known on many streams in southern Idaho and northeastern Nevada. Some of the peak discharges have recurrence intervals greater than a hundred years. The floods resulted from an unusual combination of conditions, each of which contributed to the sudden severe flooding....
Ground-water provinces of Brazil
Robert Schneider
1962, Water Supply Paper 1663-A
As part of a study of the status of investigations and development of ground water in Brazil, made under the auspices of the United States International Cooperation Administration and with the cooperation of the Government of Brazil, the country was divided into seven ground-water provinces. The identification and delineation of...
A formula for computing transmissibility causing maximum possible drawdown due to pumping
G.M. Robinson, Herbert E. Skibitzke
1962, Water Supply Paper 1536-F
By modifying the Theis nonequilibrium formula a relation is found in which the maximum possible drawdown is expressed in terms of a unique value for the aquifer coefficient of transmissibility. The relation is valid for any specified period and rate of pumping, for a given aquifer coefficient of storage, and...
Geology of the Straight Creek tunnel site, Clear Creek and Summit Counties, Colorado, and its predicted effect on tunnel construction
Charles Sherwood Robinson, Fitzhugh T. Lee
1962, Open-File Report 62-111
The purpose of this report is to present the preliminary results of the geologic and geophysical research conducted by the U. S. Geological Survey at the surface over the proposed Straight Creek tunnel. The results are interpreted and predictions are made, based primarily on statistical analyses, as to the probable...
Epigenetic uranium deposits in the United States, exclusive of Alaska and Hawaii
Arthur Pierce Butler, Warren Irvin Finch, William Stephens Twenhofel
1962, Mineral Investigations Resource Map 21
Productive and unproductive deposits of uranium in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. These deposits constitute the actual and some of the potential domestic raw-material sources of uranium. Other potential sources of uranium similar to these known deposits remain to be discovered...
