A thermodynamic study of pyrite and pyrrhotite
P. Toulmin III, P. B. Barton Jr.
1964, Geochimica et Cosmochimica Acta (28) 641-671
Through the use of the electrum-tarnish method the following equation has been found to interrelate the composition of pyrrhotite, fugacity of sulfur, and temperature: In this equation fs2 is the fugacity of sulfur relative to the ideal diatomic gas at 1 atm, N is the mol fraction of FeS in pyrrhotite (in the...
Vapor pressure and vapor fractionation of silicate melts of tektite composition
Louis S. Walter, M. K. Carron
1964, Geochimica et Cosmochimica Acta (28) 937-951
The total vapor pressure of Philippine tektite melts of approximately 70 per cent silica has been determined at temperatures ranging from 1500 to 2100°C. This pressure is 190 ± 40 mm Hg at 1500°C, 450 ± 50 mm at 1800°C and 850 ± 70 mm at 2100° C. Determinations were...
Apparatus for continuous extraction of nonpolar compounds from water applied to determination of chlorinated pesticides and intermediates
L. Kahn, C. H. Wayman
1964, Analytical Chemistry (36) 1340-1343
A continuous, multichamber liquid-liquid extractor, with internal solvent recycle, for the extraction of nonpolar contaminants from natural waters is described. The multichamber arrangement makes it possible to judge the completeness of extraction of a given component from the aqueous stream. Recoveries as high as 100% are obtained by applying the...

Life history of lake herring in Lake Superior
William R. Dryer, Joseph Beil
1964, Fishery Bulletin (63) 493-530
The average annual commercial catch of lake herring (Coregonus artedi) in U.S. waters of Lake Superior was nearly 12 million pounds in 1929-61. This production contributed 62.4 percent of the total U.S. take of lake herring for the Great Lakes. About 90 percent of the annual catch is...

The system K2Mg2(SO4)3 (langbeinite)-K2Ca2(SO4)3 (calcium-langbeinite)
G.W. Morey, J.J. Rowe, R.O. Fournier
1964, Journal of Inorganic and Nuclear Chemistry (26) 53-58
The join between the compositions K2Mg2(SO4)3 and K2Ca2(SO4)3 was studied by means of high-temperature equilibrium quenching techniques and by means of a heating stage mounted on an X-ray diffractometer. Complete solid solution exists in the system, but at 25°C members of the solid solution series are isometric only in the composition range...
Fused rock from Köfels, Tyrol
Daniel J. Milton
1964, Tschermaks Mineralogische und Petrographische Mitteilungen (9) 86-94
The vesicular glass from Köfels, Tyrol, contains grains of quartz that have been partially melted but not dissolved in the matrix glass. This phenomenon has been observed in similar glasses formed by friction along a thrust fault and by meteorite impact, but not in volcanic glasses. The explosion of a...
Crystal chemistry and structure refinement of five hydrated calcium borates
J. R. Clark, D.E. Appleman, C. L. Christ
1964, Journal of Inorganic and Nuclear Chemistry (26) 73-95
The crystal structures of the five known members of the series Ca2B6O11·xH2O (x = 1, 5, 5, 7, 9, and 13) have been refined by full-matrix least-squares techniques, yielding bond distances and angles with standard errors of less than 0·01 Å and 0·5°,...
Pentaborate polyanion in the crystal structure of ulexite, NaCaB5O6(OH)6*5H2O
Joan R. Clark, Daniel E. Appleman
1964, Science (145) 1295-1296
Triclinic ulexite crystals contain isolated borate polyanions [B5O6(OH)6]3- related to the well known pentaborate polyanion [B5O6(OH)4]- by addition of two hydroxyl groups to two opposite B-O triangles. The isolated ulexite polyanions form the [B5O7(OH)4]n3n- chains previously found in crystals of the related mineral probertite, NaCaB5O7(OH)4·3H2O....

Geology and ground-water conditions of Clark County, Washington, with a description of a major alluvial aquifer along the Columbia River
Maurice John Mundorff
1964, Water Supply Paper 1600
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local...
Studies of pre-Selma Cretaceous core samples from the outcrop area in western Alabama
Watson Hiner Monroe, Richard E. Bergenback, Norman F. Sohl, Esther R. Applin, Estella B. Leopold, Helen M. Pakiser, Louis C. Conant
1964, Bulletin 1160
In 1954 four core holes were drilled in the pre-Selma Cretaceous strata of the Alabama Coastal Plain in order to get unweathered samples within a few miles of the outcrops. During the next few years several specialists studied the cores, and their reports are published as consecutive parts of this...
