Marine Cretaceous-Tertiary boundary section in southwestern South Dakota
Dennis O. Terry Jr., John A. Chamberlain Jr., Philip W. Stoffer, Paula Messina, Patricia Jannett
2001, Geology (29) 1055-1058
A distinctive zone of disrupted strata, which we interpret as a distal manifestation of the end-Cretaceous Chicxulub impact event, occurs over 300 km2 in southwestern South Dakota. This disrupted zone is within the Fox Hills Formation, ranges from 0.5 to 5 m in thickness, and contains large-scale slump-roll structures, clastic dikes,...

Effects of urban development on stormwater runoff characteristics for the Houston, Texas, metropolitan area
Fred Liscum
2001, Water-Resources Investigations Report 2001-4071
A study was done to estimate the effects of urban development in the Houston, Texas, metropolitan area on nine stormwater runoff characteristics. Three of the nine characteristics define the magnitude of stormwater runoff, and the remaining six characteristics describe the shape and duration of a storm hydrograph. Multiple linear regression...

Gold recycling in the United States in 1998
Earle B. Amey
2001, Circular 1196-A
In 1998, 175 metric tons (t) of refined gold was recovered by U.S. refiners from old and new scrap. The overall recycling rate was 29 percent when scrap consumption was compared with apparent domestic supply. Sources of old scrap includes discarded jewelry, dental materials, plating solutions, and electronic equipment. A...

Origin, extent, and thickness of quaternary geologic units in the Willamette Valley, Oregon
Jim E. O'Connor, Andrei M. Sarna-Wojcicki, Karl C. Wozniak, Danial J. Polette, Robert J. Fleck
2001, Professional Paper 1620
Stratigraphic and chronologic information collected for Quaternary deposits in the Willamette Valley, Oregon, provides a revised stratigraphic framework that serves as a basis for a 1:250,000-scale map, as well as for thickness estimates of widespread Quaternary geologic units. We have mapped 11 separate Quaternary units that are differentiated on the...
