Two oil types on the North Slope of Alaska: implications for future exploration
Leslie B. Magoon, George Edwin Claypool
1979, Open-File Report 79-1649
Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first type, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age...
Coal resources of southeastern Massachusetts assessed in 1942
Newton Earl Chute
1979, Open-File Report 79-1140
Large easily mined coal deposits of usable quality would be of great value to Massachusetts, particularly in war time. Every effort has been made in this study to evaluate the probable occurrence, quantity, and quality of the coal deposits in southeastern Massachusetts but unfortunately it is impossible from surface observations...
Seismic, magnetic, and geotechnical properties of a landslide and clinker deposits, Powder River basin, Wyoming and Montana
C.H. Miller
1979, Open-File Report 79-952
Exploitation of vast coal and other resources in the Powder River Basin has caused recent, rapid increases in population and in commercial and residential development and has prompted land utilization studies. Two aspects of land utilization were studied for this report: (1) the seismic and geotechnical properties of a landslide...
Variation of alluvial-channel width with discharge and character of sediment
W. R. Osterkamp
1979, Water-Resources Investigations Report 79-15
Use of channel measurements to estimate discharge characteristics of alluvial streams has shown that little agreement exists for the exponent of the width-discharge relation. For the equation Q = aWAb, where Q is mean discharge and WA is active-channel width, it is proposed that the exponent, b, should be of...
Baseline water quality of Iowa's coal region
Larry J. Slack
1979, Open-File Report 79-980
To assist the Iowa Department of Environmental Quality in determining the effects that coal mining and attendant activities will have on the water quality of Iowa streams, the U.S. Geological Survey collected three sets of water-quality samples (representative of high, average, and low streamflow) in the White Breast, English,aand Cedar...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Clear Creek, Monroe County, Indiana
William G. Wilber, Charles G. Crawford, James G. Peters, Frank P. Girardi
1979, Open-File Report 79-1533
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Clear Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality...
Trace metals in surface sediments of the Mid-Atlantic Continental Shelf
Michael H. Bothner
1979, Open-File Report 79-843
The concentrations of 9 trace metals (Fe, Pb,Zn, Ba, Cu, Ni, V, Cr, and Cd) in surficial Continental Shelf sediments are low compared to the concentrations reported for average crustal rocks. No evidence for the accumulation of anthropogenic trace metals was found at the 51 locations sampled in this study....
Mineralogy as a guide for exploration in the Montezuma District, central Colorado
Theodore Botinelly
1979, Open-File Report 79-1177
The Montezuma district of central Colorado is a small base metal-silver mining district containing vein deposits associated with a Tertairy porphyry stock. The distribution of tetrahedrite having large unit-cell edges correlates in part with the distribution of more productive mines and suggests areas favorable for further production. The abundance of...
