Geologic Settings of Subsidence
Alice S. Allen
David J. Varnes, George Kiersch, editor(s)
1969, Book chapter, Reviews in Engineering Geology
This paper reviews the role of geologic processes that contribute to subsidence in order to aid those starting investigations of ground-surface subsidence. Subsidence occurs, or at least is discovered, only infrequently, and little organized information has been available. In order to assess our present state of knowledge, the author gathered...

The Cloudy Pass epizonal batholith and associated subvolcanic rocks
Fred W. Cater
1969, Book chapter, The Cloudy Pass epizonal batholith and associated subvolcanic rocks
The Cloudy Pass batholith, one of several small epizonal Tertiary batholiths in the Northern Cascade Mountains, discordantly intrudes metamorphic rocks of pre-Late Cretaceous age. The batholith is remarkable for its chilled borders, associated porphyry plugs, and intrusive breccias. The main body of the batholith consists largely of labradorite granodiorite.Part of...
Structural geology of the Quad-Wyoming-Line Creeks area, Beartooth Mountains, Montana
Lawrence C. Rowan
Leonard H. Larsen, Martin Prinz, Vincent Manson, editor(s)
1969, Book chapter, Igneous and Metamorphic Geology
The Quad-Wyoming-Line Creeks area is in the northeastern part of the Beartooth Mountains of Montana. The rocks of the area consist mainly of banded migmatite, granitic gneisses, amphibolite, quartzite, and agmatite; small amounts of biotite schist and biotite gneiss, iron-silicate rocks, ultramafic rocks, mafic dikes, and felsic porphyries are also...

Photogrammetry with surface-based images
Raymond M. Batson
1969, Applied Optics (8) 1315-1322
Stereoscopic pictures returned by surface-based imaging systems can be used to reconstruct the topography of landing sites on Mars and other planets. Large surface relief with respect to distance and the large scale variation inherent in surface-based pictures produce problems in stereoscopic measurement very different from those presented by high...

Fishery survey of U. S. waters of Lake Ontario
LaRue Wells
1969, Technical Report 14
Gill nets and trawls were fished by the Bureau of Commercial Fisheries R/V Cisco during September 19-23, 1964, at several locations and depths in the offshore United States waters of Lake Ontario. Water temperatures were low (3.7-8.3 A?C) at all fishing stations except one (16.4 A?C). Supplementary data were provided...

Survival in wood duck broods
Frank B. McGilvrey
1969, Journal of Wildlife Management (33) 73-76
Mortality of wood ducklings (Aix sponsa) from hatching to 6 weeks of age averaged 47 percent during a 4-year study at the Patuxent Wildlife Research Center. Over 90 percent of the total mortality occurred during the first 2 weeks of life. Brood bonds began to dissolve after the fifth week....
Ecological relationships of breeding blue-winged teal to prairie potholes
Rod C. Drewien, P. F. Springer
1969, Report Series 6
Ecology of breeding blue-winged teal (Anas discors) was studied on the Waubay Study Area in Day County, South Dakota, in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Changes in breeding pair densities and wetland habitat...

Laboratory studies on antimycin A as a fish toxicant
Bernard L. Berger, Robert E. Lennon, James W. Hogan
1969, Investigations in Fish Control 26
Liquid and sand formulations of antimycin A were tested in laboratory waters of various temperature, hardness, pH, and turbidity against 31 species of fresh-water fish of various sizes and life stages. Each formulation of toxicant was lethal under all water conditions to fish eggs, fry, fingerlings, and adult fish. Trouts...

The morphology and chronology of a landslide near Dillon Dam, Dillon, Colorado
E.E. Wahlstrom, T. C. Nichols Jr.
1969, Engineering Geology (3) 149-174
Investigations were made of a landslide at the Dillon Dam site, Dillon, Colo., that included detailed laboratory and field analyses of the mineralogy, chemistry, and physical properties of landslide materials and the bedrock formations from which they were derived. These investigations provide an understanding of the relative importance of various...
The determination of nanogram amounts of Chromium in urine by x-ray fluorescence spectroscopy
K. Beyermann, H. J. Rose Jr., R.P. Christian
1969, Analytica Chimica Acta (45) 51-55
Nanogram amounts of chromium can be extracted as oxinate into chloform. By treatment of the chloroform layer 3 M hydrochloric acid, oxinates of other elements and excess of reagent are removed, leaving a chloroform solution of the chromium chelate only. This solution is concentrated and transferred to...
