User's guide to the Radiometric Age Data Bank (RADB)

1976, Open-File Report 76-674
The Radiometric Age Data Bank (RADB) has been established by the U.S. Geological Survey, as a means for collecting and organizing the estimated 100,000 radiometric ages presently published for the United States. RADB has been constructed such that a complete sample description (location, rock type, etc.), literature citation, and extensive...

Preliminary investigations on computational methods for solving the two-point seismic ray-tracing problem in a heterogeneous and isotropic medium
J.P. Yang, William Hung Kan Lee
1976, Open-File Report 76-707
Two-point seismic ray tracing is an important problem in seismology. In this report, we study this problem by first deriving the differential equations governing seismic wave propagation between two end points in a 3-dimensional heterogeneous and isotropic medium. We then formulate three numerical schemes to solve the two-point ray-tracing problem....

CABFAC/USGS, a FORTRAN program for Q-mode factor analysis of stratigraphically ordered samples
David P. Adams
1976, Open-File Report 76-216
This program is a revision of the CABFAC program of Kovan and Imbrie (1971) which incorporates the following improvements: each factor is plotted against depth on the printer; samples are ordered stratigraphically by the program, so that input data need not be ordered stratigraphically; an option has been added to...

The potentiometric surface of the Magothy Aquifer on Long Island, New York, in March 1975
Keith R. Prince
1976, Open-File Report 76-536
A map showing the potentiometric surface of the Magothy aquifer was drawn from water-level measurements made in March 1975. These measurements indicated a range in altitude of the potentiometric surface from more than 25 feet (7.62 metres) below mean sea level in Queens County to more than 80 feet (24.38...
A probabilistic estimate of maximum acceleration in rock in the contiguous United States
Sylvester Theodore Algermissen, David M. Perkins
1976, Open-File Report 76-416
This paper presents a probabilistic estimate of the maximum ground acceleration to be expected from earthquakes occurring in the contiguous United States. It is based primarily upon the historic seismic record which ranges from very incomplete before 1930 to moderately complete after 1960. Geologic data, primarily distribution of faults, have...

1976, Open-File Report 76-580
Dinosaur National Monument, partly in the Rocky Mountain System and partly in the Colorado Plateaus physiographic province, covers an area of 322 square miles (834 square kilometres) in northwestern Colorado and northeastern Utah. The climate is generally cool and pleasant in May, early June, September, and October; winters are cold....

Flood frequency: expected and unexpected probabilities
D. M. Thomas
1976, Open-File Report 76-775
Flood-frequency curves may be defined either with or without an ' expeced probability ' adustment; and the two curves differ in the way that they attempt to average the time-sampling uncertainties. A curve with no adustment is shown to estimate a median value of both discharge and frequency of occurrence,...

Mineral resources of Elko County, Nevada
Roscoe Maurice Smith
1976, Open-File Report 76-56
Of the 66 named mining districts in Elko County, 56 have been productive of one or more of 19 different commodities: 11 metals--copper, gold, silver, lead, zinc, mercury, tungsten, manganese, iron, uranium, and antimony; 8 nonmetals--sand and gravel, stone, barite, diatomite, gems, oil shale, volcanic ash, and clay. In addition...
