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...

New activities at the U.S. Geological Survey
Vincent E. McKelvey
1974, Report
As the Nation's principal source of information about the configuration of the land surface, the composition and structure of the rocks at and beneath the surface, the distribution and character of its energy, mineral, and water resources, and the nature of natural geologic processes, the U. S. Geological Survey focuses...
Studying the Earth from space
Water Resources Division, U.S. Geological Survey
1974, Report
Pictures of the Earth's surface obtained from satellites are providing scientists with new tools to investigate tne Earth and its environment. A growing population and an everexpanding technology place demands on our natural resources. However, man can no longer treat his resources strictly according to immediate economic dictates; a balance...
Shore zone land use and land cover: Central Atlantic Regional Ecological Test Site
R. Dolan, B.P. Hayden, C.L. Vincent
1974, Natural Resources Report 8
Anderson's 1972 United States Geological Survey classification in modified form was applied to the barrier-island coastline within the CARETS region.

Presentation and interpretation of chemical data for igneous rocks
T. L. Wright
1974, Contributions to Mineralogy and Petrology (48) 233-248
Arguments are made in favor of using variation diagrams to plot analyses of igneous rocks and their derivatives and modeling differentiation processes by least-squares mixing procedures. These methods permit study of magmatic differentiation and related processes in terms ofall of the chemical data available. Data are presented as they are reported...
