PDF Selenium and stable isotopes of carbon and nitrogen in the benthic clam Corbula amurensis from Northern San Francisco Bay, California: May 1995-February 2010 [More info]
Monthly selenium concentration in this keystone species shows strong spatial and seasonal variation in a five-year series of analyses.
PDF Tellurium: providing a bright future for solar energy [More info]
Explains how we use this extremely rare element, where we obtain it, and describes the global supply and demand situation for the commodity.
PDF The concept of geologic carbon sequestration [More info]
Explains securing carbon dioxide in deep geologic formations to prevent its release to the atmosphere and contribution to global warming as a greenhouse gas.
PDF The future of rare earth elements--will these high-tech industry elements continue in short supply? [More info]
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
PDF The principal rare earth elements deposits of the United States-A summary of domestic deposits and a global perspective [More info]
Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
PDF The rare-earth elements: vital to modern technologies and lifestyles [More info]
Explains where and how deposits of these elements form, trends in supply and demand, how we use them, and how they may affect the environment.
PDF Thermal Properties of Methane Gas Hydrates [More info]
This unusual form of hydrocarbons can alter the thermal properties of host sediments; the analysis presented here helps us understand how those sediments might behave under natural or human-induced changes in the environment.
PDF Tintina gold province study, Alaska and Yukon Territory, 2002-2007 [More info]
New discoveries and modernized extraction methods prompted renewed interest in gold deposits in this part of central Alaska, prompting a variety of studies described here.
PDF Titanium: light, strong, and white [More info]
Titanium is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier.
PDF Trace elements in coal ash [More info]
Describes and explains the material remaining when coal is burned, especially the trace elements present in it which may be concentrated by the burning process.
