Utilization of humus-rich forest soil (mull) in geochemical exploration for gold
Gary C. Curtin, H. W. Lakin, G. J. Neuerburg, A.E. Hubert
1968, Circular 562
Distribution of gold in humus-rich forest soil (mull) reflects the known distribution of gold deposits in bedrock in the Empire district, Colorado. Gold from the bedrock is accumulated by pine and aspen trees and is concentrated in the mull by the decay of organic litter from the trees. Anomalies in...
Geochemical and geophysical anomalies in the western part of the Sheep Creek Range, Lander County, Nevada
Garland Bayard Gott, Charles J. Zablocki
1968, Circular 595
Extensive geochemical anomalies are present along the west side of the Sheep Creek Range in Lander County, Nev. Anomalous concentrations of zinc, arsenic, mercury, silver, copper, lead, and to some extent gold, molybdenum, and antimony occur in iron-rich material along fracture planes and in quartz veins in Paleozoic formations. A...
Frequency curves
H. C. Riggs
1968, Techniques of Water-Resources Investigations 04-A2
This manual describes graphical and mathematical procedures for preparing frequency curves from samples of hydrologic data. It also discusses the theory of frequency curves, compares advantages of graphical and mathematical fitting, suggests methods of describing graphically defined frequency curves analytically, and emphasizes the correct interpretations of a frequency curve....
Estimated use of water in the United States, 1965
Charles Richard Murray
1968, Circular 556
Estimates of water use in the United States for 1965 indicate that an average of about 310 bgd (billion gallons per day) were withdrawn for public-supply, rural domestic and livestock, irrigation, and industrial (including thermoelectric power)uses--that is, about 1,600 gallons per capita per day. This represents an increase of 15...
Chemical quality of surface waters in Devils Lake basin North Dakota, 1952-60
Hugh T. Mitten, C.H. Scott, Philip G. Rosene
1968, Water Supply Paper 1859-B
Above-normal precipitation in 1954, 1956, and 1957 caused the water surface of Devils Lake to rise to an altitude of 1,419.3 feet, its highest in 40 years. Nearly all the water entering the lake flowed through Big Coulee, and about three-fourths of that inflow was at rates greater than 100...
