In search of a statistical probability model for petroleum-resource assessment : a critique of the probabilistic significance of certain concepts and methods used in petroleum-resource assessment : to that end, a probabilistic model is sketched
Bernardo F. Grossling
1975, Circular 724
Exploratory drilling is still in incipient or youthful stages in those areas of the world where the bulk of the potential petroleum resources is yet to be discovered. Methods of assessing resources from projections based on historical production and reserve data are limited to mature areas. For most of the...

M. E. Yount, editor(s)
1975, Circular 722
This report on the Alaskan activities of the U.S. Geological Survey contains up-to-date accounts of recent results and summaries of plans for the summer of 1975. It is organized in six parts: (1} responsibilities and services of the Geological Survey; (2} organization of the U.S. Geological Survey; (3) U.S. Geological...
A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...
Preliminary report on the use of LANDSAT-1 (ERTS-1) reflectance data in locating alteration zones associated with uranium mineralization near Cameron, Arizona
Charles S. Spirakis, Christopher D. Condit
1975, Open-File Report 75-416
LANDSAT-I (ERTS-I) multispectral reflectance data were used to enhance the detection of alteration around uranium deposits near Cameron, Ariz. The technique involved stretching and ratioing computer-enhanced data from which electronic noise and atmospheric haze had been removed. Using present techniques, the work proves that LANDSAT-I data are useful in detecting...
Test drilling at Soldier Creek, Rosebud Indian Reservation, Todd County, South Dakota
D. G. Adolphson
1975, Open-File Report 75-355
Thirty-six test holes were augered by the U.S. Geological Survey in the vicinity of Sol,,r Creek, Rosebud Indian Reservation, Todd County, South Dakota. Wells prcducing more than S gallons per minute (0.32 litre per second) from the Tertiary deposits are rare. However, as much as 20 feet (6.1 metres) of...
A summary of relative ages of lunar nearside and farside plains
Joseph M. Boyce, Arthur L. Dial, Laurence A. Soderblom
1975, Open-File Report 75-141
This report contains a summary of the moon-wide distribution of relative ages of lunar plains units determined with Apollo and Lunar Orbiter photographs. Relative ages are expressed as the largest diameter of craters (DL, meters) in a mappable unit that are eroded to a slope of 1° by the net...
Abundances of uranium, thorium, and potassium for some Australian crystalline rocks
Carl Maurice Bunker, C. A. Bush, Robert J. Munroe, J.H. Sass
1975, Open-File Report 75-393
This report contains a tabulation of the basic radioelement and radiogenic heat data obtained during an Australian National University (ANU) - United States Geological Survey (USGS) heat-flow project, directed jointly by J. C. Jaeger (ANU) and J. H. Sass (USGS). Most samples were collected during the periods June through September,...
