Analyses and economic potential of monazite in Liberia
Sam Rosenblum
1974, Journal of Research of the U.S. Geological Survey (2) 689-692
Eleven monazite samples from Liberia, including seven from beach sands, were analyzed by the X-ray fluorescence method. The monazite samples, containing only one-half percent impurities, were obtained by use of a hot Clerici-solution procedure for purification which was devised by the author. The percentage of the rare-earth elements in Liberian...
Volcanic hazards on the Island of Hawaii
Donal Ray Mullineaux, Donald W. Peterson
1974, Open-File Report 74-239
Volcanic hazards on the Island of Hawaii have been determined to be chiefly products of eruptions: lava flows, falling fragments, gases, and particle-and-gas clouds. Falling fragments and particle-and-gas clouds can be substantial hazards to life, but they are relatively rare. Lava flows are the chief hazard to property; they are...

Mortimer H. Staatz, Van E. Shaw, James S. Wahlberg
1974, Journal of Research of the U.S. Geological Survey (2) 677-683
Rare earths, although equal to or more abundant than thorium in many thorium veins, are much less abundant than thorium in the veins on Hall Mountain, Idaho. Total rare-earth content of these veins ranges from 0.00111 to 0.197 percent in 12 samples from 10 veins; the thoria (ThO2 ) content,...
An experimental study of the partitioning of a rare earth element (Gd) in the system diopside—Aqueous vapour
Robert A. Zielinski, Frederick A. Frey
1974, Geochimica et Cosmochimica Acta (38) 545-565
The partitioning of Gd in the experimental system diopside-aqueous vapor as a function of temperature, pressure, composition of the phases, time, grain size, solid-liquid ratio and Gd concentration has been investigated. A radioactive tracer measurement was used to determine Gd concentration in the separated phases. Diposides were reacted with aqueous...

Leslie A. Sirkin
1974, Journal of Research of the U.S. Geological Survey (2) 431-440
Palynologic analysis of core samples from Fire Island well, S21,091T, in southern Long Island and of surface samples from Garvies Point in northern Long Island and from eastern Block Island indicates that the Cretaceous of this region includes Raritan, Magothy, Matawan, and Monmouth (as previously defined) strata, and ranges in...
The literature of the California black rail
Sanford R. Wilbur
1974, Special Scientific Report - Wildlife 179
Few birds have remained so little known as the California black rail (Laterallus jamaicensis coturniculus). Although first collected in 1859 or before and reported in 1874 (Ridgway 1874), its life history, distribution, and status have remained so obscure that even a sight record of the bird is deemed worthy of...

C. Ervin Brown
1974, Journal of Research of the U.S. Geological Survey (2) 219-232
The basal beds of the Maquoketa Shale in northeastern Iowa include a basal silty phosphorite layer that is thickest near Dubuque. In Clayton County, Iowa, the bed averages about 1 foot thick (30 centimeters) and contains 22.5 percent P205 . Phosphatic dolomite that is 8 10 feet (2.4 3 meters)...
The California condor in the Pacific Northwest
S.R. Wilbur
1973, The Auk (90) 196-198
The California Condor (Gymnogyps californianus), once found along the Pacific Coast from Baja California to British Columbia, had become very rare north of California by 1850. Koford (1953), summarizing information available on the species in the Pacific Northwest, tentatively concluded that birds seen in that area were wanderers from California,...
Erosional and Depositional Aspects of Hurricane Camille in Virginia, 1969
Garnett P. Williams, Harold P. Guy
1973, Professional Paper 804
Probably the worst natural disaster in central Virginia's recorded history was the flood resuiting from an 8-hour deluge of about 28 inches (710 mm) of rain on the night of August 19-20, 1969. This study examines some of the intensive sediment erosion and deposition that resulted from the storm and...

Chapter E adds 112 described species and subspecies (a few briefly described) to the some 440 covered in preceding chapters : 27 additional gastropods, 18 scaphopods, and 67 pelecypods in 10 families. It is estimated that about 125 species are to be added in chapter F, the final chapter.The Arcidae...

Gold abundance in igneous rocks; bearing on gold mineralization
Robert I. Tilling, David Gottfried, Jack J. Rowe
1973, Economic Geology (68) 168-186
Review of quantitative data, restricted range in gold content (rarely more than 10 ppb, generally below 5 ppb), mafic rocks have more, so do early crystallizing minerals, no use in exploration, factors other than concentration determine mineralization; examples...

Donald E. Lee, Harry J. Rose Jr., Elaine L. Munson Brandt, Richard E. Van Loenen
1973, Journal of Research of the U.S. Geological Survey (1) 267-272
Chemical and physical data are given for five samples of rock-forming apatite from diverse geologic environments in Nevada and Colorado. Four of these apatites contain rare-earth assemblages in which the cerium group is well represented but the yttrium group predominates. The fifth apatite contains a highly fractionated assemblage of the lighter (cerium group) rare earths...

John Van N. Dorr
1973, Economic Geology (68) 1005-1022
Except for recent studies by certain South American governmental and quasi-governmental companies and agencies, little effort has been devoted to study of the iron-formations from which the great iron ore deposits of South America formed. Great gaps in basic information exist. Iron-formation is found in the Guayana and Brazilian Precambrian...
