Contribution to the study of the physico-chemical structure of Clais
Remy Hebert, S. E. Britt (translator)
1954, Open-File Report 54-28
The Cormeilles-en-Parisis hill shows one of the best geologic sections of the Paris region. The 80 meter high working face of the quarry exposes the complete section of the "Ludian" [the youngest beds of the Eocene] with its alternations of the marl and gypsum. Above is the sequence of supra-gypseous...
Surface adsorption of Cs137 ions on quartz crystals
Stephen Antkiw, H. Waesche, F. Senftle
1954, Trace Elements Memorandum 862
Adsorption tests were made on four large synthetic and three natural quartz crystals to see if surface defects might be detected by subsequent autoradiography techniques. The adsorbent used was radioactive Cs137 in a solution of Cs 137Cl. Natural quartz crystals adsorbed more cesium than the synthetic crystals. Certain surface defects...
Identification and occurrence of uranium and vanadium minerals from the Colorado Plateaus
A. D. Weeks, M.E. Thompson
1954, Bulletin 1009-B
This report, designed to make available to field geologists and others informa- tion obtained in recent investigations by the Geological Survey on identification and occurrence of uranium minerals of the Colorado Plateaus, contains descriptions of the physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis...
Magnetite deposits at Tuxedni Bay, Alaska
Arthur Grantz
1954, Open-File Report 54-103
The magnetite deposits on an island in Tuxedni Bay occur in contact-metamorphosed volcanic and sedimentary rocks near their contact with a quartz diorite batholith which underlies large areas of the adjacent Aleutian Range. The deposits are pyrometasomatic in origin and are localized along northeast-trending fractures. The eastern deposit is a...
Availability of primary or juvenile water for ordinary uses
C. L. McGuinness, J. F. Poland
1954, Open-File Report 54-178
Progressive depletion of the water supplies of many of the desert valleys of the Southwest, both because of recurrent droughts and because of overdevelopment, has focused increasing attention on the possibilities of developing supplementary water supplies from sources that are immune to drought, or at least whose development will not...
