Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
Explains securing carbon dioxide in deep geologic formations to prevent its release to the atmosphere and contribution to global warming as a greenhouse gas.
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.
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.
Iron ore containing elevated concentrations of trace metals was smelted here during 113 years of operation (1771-1883). We sampled a variety of materials nearby to determine the amount of metals such as arsenic, chromium, copper, lead, and zinc.
Research findings and examples of application to real problems--chemical reactions between nitrate, iron, and oxygen can affect the mobility of trace amounts of arsenic.
