Coulomb 3.3 Graphic-rich deformation and stress-change software for earthquake, tectonic, and volcano research and teaching-user guide
Shingi Toda, Ross S. Stein, Volkan Sevilgen, Jian Lin
2011, Open-File Report 2011-1060
Coulomb is intended both for publication-directed research and for college and graduate school classroom instruction. We believe that one learns best when one can see the most and can explore alternatives quickly. So the principal feature of Coulomb is ease of input, rapid interactive modification, and intuitive visualization of the...

Dating of Pliocene Colorado River sediments: implications for cosmogenic burial dating and the evolution of the lower Colorado River
Ari Matmon, Greg M. Stock, Darryl E. Granger, Keith A. Howard
2011, Geological Society of America Bulletin (124) 626-640
We applied cosmogenic 26Al/10Be burial dating to sedimentary deposits of the ancestral Colorado River. We compared cosmogenic burial ages of sediments to the age of an independently well-dated overlying basalt flow at one site, and also applied cosmogenic burial dating to sediments with less precise independent age constraints. All dated...

Flow studies for recycling metal commodities in the United States
Scott F. Sibley
2011, Circular 1196
As world population increases and the world economy expands, so does the demand for natural resources. An accurate assessment of the Nation's mineral resources must include not only the resources available in the ground but also those that become available through recycling. Supplying this information to decisionmakers is an essential...

Using dissolved gases to observe the evolution of groundwater age in a mountain watershed over a period of thirteen years
Andrew H. Manning
2011, Conference Paper
Baseflows in snowmelt-dominated mountain streams are critical for sustaining ecosystems and water resources during periods of greatest demand. Future climate predictions for mountainous areas throughout much of the western U.S. include increasing temperatures, declining snowpacks, and earlier snowmelt periods. The degree to and rate at which these changes will affect...

Overview of flow studies for recycling metal commodities in the United States
Scott F. Sibley
2011, Circular 1196-AA
Metal supply consists of primary material from a mining operation and secondary material, which is composed of new and old scrap. Recycling, which is the use of secondary material, can contribute significantly to metal production, sometimes accounting for more than 50 percent of raw material supply. From 2001 to 2011,...
