Geology of the Gore Canyon-Kremmling area, Grand County, Colorado
C.S. Venable Barclay
1968, Open-File Report 68-3
The Gore Canyon-Kremmling area is in the southwestern portion of the Kremmling 15-minute quadrangle, Colorado. Precambrian rocks are biotite gneiss, the Boulder Creek Granodiorite, granophyre dikes, and quartz veins. The Boulder Creek intrudes the biotite gneiss, and both of these units are cut by north-northwest-trending granophyre dikes and quartz veins....

Map showing recently active breaks along the Hayward fault zone and the southern part of the Calaveras fault zone, California
Dorothy H. Radbruch
1968, Open-File Report 68-220
This map is one of a set that shows the traces of the inferred most recently active faults of the San Andreas and related fault zones of the San Andreas fault systems (Cromwell, 1962.) It was compiled primarily to provide information for those concerned with land use and development on...

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...

Gold distribution on the sea floor off the Klamath Mountains, California
George William Moore, Eli A. Silver
1968, Circular 605
Analyses of 82 samples collected from the surface of the continental shelf between the Oregon-California border and Eureka, Calif., indicate that the background gold content on this shelf is about 0.1 ppb (part per billion). Four anomalous tracts, which range in extent from 10 to 30 square kilometers, have gold...
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...
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...
An atomic-absorption method for the determination of gold in large samples of geologic materials
Gordon H. VanSickle, Hubert William Lakin
1968, Circular 561
A laboratory method for the determination of gold in large (100-gram) samples has been developed for use in the study of the gold content of placer deposits and of trace amounts of gold in other geologic materials. In this method the sample is digested with bromine and ethyl ether, the...
