U.S. mineral dependence—Statistical compilation of U.S. and world mineral production, consumption, and trade, 1990–2010

The report provides insight into the dependence of the United States on foreign supply to meet the country’s mineral needs. This overview highlights the importance of understanding what is happening at each point along the supply chain.

A preliminary full spectrum magnetic anomaly grid of the United States with improved long wavelengths for studying continental dynamics

The long-wavelength (50-2,500 km) content of the regional magnetic anomaly compilation was improved by utilizing a nearly homogeneous a nearly homogeneous set of NURE magnetic surveys flown from 1975 to 1981
