David Robert Waldbaum, Richard A. Robie
1971, Zeitschrift für Kristallographie — Crystalline Materials (134) 381-420
Heat of solution measurements of the enthalpies of Na-K mixing, Al-Si ordering, and fusion for crystalline solutions and end-member phases in the system Na(AlSi3O8)–K(AlSi3O8) were obtained with a vacuum-jacketed, isoperibolic calorimeter using 20.1 percent hydrofluoric acid at temperatures ranging from 40 to 60°C. Heat of solution data for artificially prepared...

1971, Book chapter, Caribbean geophysical, tectonic, and petrologic studies
Small lenses of detrital serpentinite, completely surrounded by massive serpentinite, occur within a sequence of Mesozoic phyllites and metasiltstones in the Cerros de Parashi area, Guajira Peninsula. These lenses, which are as...
Recharge characteristics of a watercourse aquifer system at Springfield, Ohio
Stanley E. Norris, Herbert B. Eagon Jr.
1971, Groundwater (9) 30-41
An investigation was made of infiltration conditions in the alluvial-filled Mad River valley in the vicinity of the Springfield municipal wells. The study shows that most recharge to the 100-foot thick sand and gravel aquifer is from induced infiltration from the Mad River. Local precipitation and natural, down-valley underflow also...
The water resources of southeast Iowa
R. W. Coble, J.V. Roberts
1971, Iowa Geological Survey Water Atlas 4
Water is vital in the lives of the people and the economy of any area. In order to utilize this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of its sources and the occurrence and potential of each source must be gained. To provide...

Chemical compositions of rock types as factors in our environment
Harry A. Tourtelot
Helen L. Cannon, Howard C. Hopps, editor(s)
1971, Book chapter, Environmental geochemistry in health and disease
The types of rocks that form geologic units in the Earth’s crust supply most of the raw materials from which soils are formed and from which water derives its inorganic constituents. The compositions of what we eat and drink thus depend in part upon the compositions of the source rocks.Igneous...
Magnetic susceptibility and triangular exchange coupling in the tourmaline mineral group
T. Tsang, A. N. Thorpe, G. Donnay, Frank E. Senftle
1971, Journal of Physics and Chemistry of Solids (32) 1441-1448
Magnetic susceptibilities of three iron-rich tourmaline crystals from Mexquitic (Mexico), Pierpont (New York), and Madagascar with different and known chemical compositions have been studied from 8° to 300°K. The iron atoms in the tourmaline crystal structure, space group R3m, a∼15·9, c∼7·2 , are...

Palaeomagnetism and potassium-argon ages of volcanic rocks of Ngorongoro caldera, Tanzania
C. S. Grommé, T. A. Reilly, A. E. Mussett, R. L. Hay
1971, Geophysical Journal International (22) 101-115
Natural remanent magnetization (NRM) has been measured in 21 lava flows and 1 tuff in the south-west wall of Ngorongoro caldera, Tanzania. The lowest three lavas are normally magnetized, the next two have intermediate directions, and the remainder are reversed; potassium-argon dating places the reversal at 2.45 My, corresponding...

1971, Report
Studies of published and unpublished geologic and ground-water data, for an inventory of 6,032 wells and 754 springs in parts of Inyo and Mono Counties, California, and Clark, Esmeralda, Lincoln, and Nye Counties, Nevada, reveal the following information:A complex sequence of granitic, metamorphic, volcanic, and sedimentary rocks of Precambrian to...
Water resources of the Coamo area, Puerto Rico
Ennio V. Giusti
1971, Report
This study, like other similar studies, was made possible by a cooperative water-resources program between the U.S. Geological Survey and the Puerto Rico Water Resources Authority (at the time), representing also the Puerto Rico Aqueduct & Sewer Authority and the Puerto Rico Industrial Development Company.This report covers the hydrologic investigation...
Open-channel integrating-type flow meter
K.C. Koopman
1971, Report
A relatively inexpensive meter for measuring cumulative flow in open channels with a rated control,. called a "totalizer", was developed. It translates the nonlinear function of gage height to flow by use of a cam and a float. A variable resistance element in an electronic circuit is controlled by the...

1971, Conference Paper, International Workshop in Earth Resources Survey Systems
An attempt was made to investigate the potential of airborne, multispectral, line scanner data acquisition and computer-implemented automatic recognition techniques for providing useful information about waterfowl breeding habitat in North Dakota. The spectral characteristics of the components of a landscape containing waterfowl habitat can be detected with airborne scanners. By...

Biology of larval sea lampreys (Petromyzon marinus) of the 1960 year class, isolated in the Big Garlic River, Michigan, 1960-65
Patrick J. Manion, Alberton L. McLain
1971, Technical Report 16
The early life history of the sea lamprey, from hatching to the first capture of metamorphosed individuals, is described from observations on a known-age population isolated in a tributary of southern Lake Superior. The population had its origin in the spring of 1960, when 722 sea lampreys nearing spawning condition...
Geysers
1971, Report
A geyser is a special type of hot spring that from time to time spurts water above ground. It differs from most hot springs in having periodic eruptions separated by intervals without flow of water. The temperature of the erupting water is generally nearly at boiling for pure water (212°F...

1971, Icarus (14) 388-418
The Apollo whole-disk lunar photographs, with spacecraft lunar nadirs about 70° from the center of mean face, have considerable selenodetic potential provided that the requirements of resolution and precision can be met. Uncertainties in the internal camera geometry degrade the precision and make...
Selective food preferences of walleyes of the 1959 year class in Lake Erie
John W. Parsons

Stomachs were examined from 1,473 walleyes (Stizostedion vitreum vitreum) of the 1959 year class collected in western Lake Erie from June 1959 to October 1960. In the same period, the relative abundance and lengths of potential forage species were determined from trawl catches. The walleye fed almost entirely on fish....
