Applications of U.S. Geological Survey digital cartographic products, 1979-1983
Thomas R. Loveland, Benjamin S. Ramey
1986, Bulletin 1583
The U.S. Geological Survey prepares and distributes fundamental, multipurpose cartographic data to a wide range of users throughout the United States. Recognizing that traditional cartographic procedures will eventually be replaced by digital techniques, the USGS is now actively developing computer-based methods to produce digital cartographic products. The digital cartographic products...
Field and laboratory procedures used in a soil chronosequence study
Michael J. Singer, Peter Janitzky, editor(s)
1986, Bulletin 1648
In 1978, the late Denis Marchand initiated a research project entitled "Soil Correlation and Dating at the U.S. Geological Survey" to determine the usefulness of soils in solving geologic problems. Marchand proposed to establish soil chronosequences that could be dated independently of soil development by using radiometric and other numeric...
Geologic and grade-tonnage information on Tertiary epithermal precious- and base-metal vein districts associated with volcanic rocks
Dan L. Mosier, W. David Menzie, Frank J. Kleinhampl
1986, Bulletin 1666
Data on grades, tonnages, and geology of selected Tertiary epithermal precious- and base-metal vein districts associated with volcanic rocks were tabulated for ease of examination and comparison of characteristics between districts. There are 215 districts listed, with a cumulative tonnage of 709 million metric tons and average grades of...
Cost effectiveness of the US Geological Survey's stream-gaging programs in New Hampshire and Vermont
J.A. Smath, F.E. Blackey
1986, Water-Resources Investigations Report 85-4173
Data uses and funding sources were identified for the 73 continuous stream gages currently (1984) being operated. Eight stream gages were identified as having insufficient reason to continue their operation. Parts of New Hampshire and Vermont were identified as needing additional hydrologic data. New gages should be established in these...
