Ice ages and the thermal equilibrium of the earth, II
D.P. Adam
1975, Quaternary Research (5) 161-171
The energy required to sustain midlatitude continental glaciations comes from solar radiation absorbed by the oceans. It is made available through changes in relative amounts of energy lost from the sea surface as net outgoing infrared radiation, sensible heat loss, and latent heat...
Elevation changes in the central Transverse Ranges near Ventura, California
Jane M. Buchanan-Banks, Robert O. Castle, Joseph I. Ziony
1975, Tectonophysics (29) 113-125
Profiles of elevation changes developed from repeated levelings in the east-trending Transverse Ranges near Ventura, California, reveal three general types of vertical movements: 1. (1) broadly defined regional tilting; 2. (2) sharply defined differential movements across recently active faults; and 3. (3) differential subsidence centering on producing oil fields. Down-to-the-southeast...

1975, Remote Sensing of Environment (4) 199-209
Emittance spectra in the 7.5 μm to 14 μm wavelength region and chemical compositions of 26 igneous rocks are reported. Experimental measurements on the rocks were made under simulated daytime field conditions. Some surface silicate contaminants, such as clayey silt, significantly...
Al-augite and Cr-diopside ultramafic xenoliths in basaltic rocks from western United States
H. G. Wilshire, J.W. Shervais
1975, Physics and Chemistry of the Earth (9) 257-272
Ultramafic xenoliths in basalts from the western United States are divided into Al-augite and Cr-diopside groups. The Al-augite group is characterized by Al, Ti-rich augites, comparatively Fe-rich olivine and orthopyroxene, and Al-rich spinel, the Cr-diopside group by Cr-rich clinopyroxene and spinel and...
Garnet peridotite xenoliths in a Montana, U.S.A., kimberlite
Hearn B. Carter Jr., F.R. Boyd
1975, Physics and Chemistry of the Earth (9) 247-255
Within a swarm of late middle Eocene subsilicic-alkalic diatremes, one diatreme 270 by 370 m and an associated dike contain common xenoliths of granulite and rare xenoliths of spinel peridotite and garnet peridotite. Six garnet lherzolite xenoliths have been found and these...
Magnitude and frequency of floods in small drainage basins in North Dakota
Orlo A. Crosby
1975, Water-Resources Investigations Report 19-75
This report describes methods for estimating flood-peak discharges having 2- to 50-year recurrence intervals on North Dakota streams draining less than 100 square miles ( 259 square kilometres). For gaged sites, frequency estimates are provided directly. For ungaged sites, flood peaks are estimated from multiple-regression equations using drainage-area size and,...
A summary of selected chemical-quality conditions in 66 California streams 1950-72
George A. Irwin, Michael Lemons
1975, Report
Water from California streams has been analyzed for concentrations of selected chemical constituents since the early 1950's. This summary includes about 1,200 water years of data from 88 sampling sites on 66 streams. Results of this summary show that about 80 percent of the sites had a mean dissolved-solids concentration...
Descriptions and chemical analyses for selected wells in the Tehama-Colusa Canal Service Area, Sacramento Valley, California
Ronald P. Fogelman
1975, Report
The Tehama-Colusa Canal Service Area is in the northwestern part of the Sacramento Valley, in parts of Yolo, Colusa, Glenn, and Tehama Counties. The area includes 450 square miles (1,160 square kilometres). The boundaries are: West, the eastern slopes of the Coast Ranges; north, Elder Creek; northeast, the Sacramento River...

Thermal-infrared images as a basis for structure mapping, front range and adjacent plains in Colorado
Terry W. Offield
1975, Geological Society of America Bulletin (86) 495-502
High-altitude thermal-infrared images, taken at various times of the day over the Front Range and adjacent plains in Colorado, display many linear and circular topographic features. These features are enhanced by thermal shading effects and commonly are better displayed than in photographs. Comparison with geologic maps of a control area...

The geologic story of Arches National Park
Stanley William Lohman
1975, Bulletin 1393
According to former Superintendent Bates Wilson (1956), Prof. Lawrence M. Gould, of the University of Michigan, was the first to recognize the geologic and scenic values of the Arches area in eastern Utah and to urge its creation as a national monument. Mrs. Faun McConkie Tanner told me that Professor...
Optimizing information transfer in a stream-gaging network
Philip Hadley Carrigan Jr., Harold G. Golden
1975, Water-Resources Investigations Report 75-30
Networks of small stream (drainage area less than 50 square miles or 130 square kilometres) flood gages have been operated throughout the country for a number of years to supplement flood information already available for large streams. The goal in operating these networks has been to obtain sufficient data for...
