Interactive computer methods for generating mineral-resource maps
James Alfred Calkins, A.S. Crosby, T.E. Huffman, A. L. Clark, G.T. Mason, R.J. Bascle
1980, Circular 815
Inasmuch as maps are a basic tool of geologists, the U.S. Geological Survey's CRIB (Computerized Resources Information Bank) was constructed so that the data it contains can be used to generate mineral-resource maps. However, by the standard methods used-batch processing and off-line plotting-the production of a finished map commonly takes...
In-situ measurements of seismic velocity at 27 locations in the Los Angeles, California region
James F. Gibbs, Thomas E. Fumal, Edward F. Roth
1980, Open-File Report 80-378
Studies conducted in the San Francisco Bay Region (Gibbs, Fumal and Borcherdt, 1980) have shown that average shear-wave velocity can be readily tied to quantitative estimates of ground motion such as ground amplification and earthquake intensity. Furthermore, when certain physical properties of the geologic materials such as texture, hardness and...
Effects of urban runoff and wastewater effluent on Wilsons Creek and James River near Springfield, Missouri
Wayne R. Berkas
1980, Water-Resources Investigations Report 80-27
Statistical analysis on water-quality parameters from James River upstream and downstream from the confluence of Wilsons Creek shows a significant difference for all parameters except temperature and dissolved silica at the 0.05 probability level. Regression analysis shows correlation for discharge with dissolved sodium, dissolved chloride, and dissolved potassium, and for...
Single-channel seismic-reflection profiles and sidescan sonar records collected during May 15-20, 1978, on the southern New England continental shelf
David C. Twichell
1980, Open-File Report 80-177
The U.S. Geological Survey completed a cruise aboard the R/V CAPE HENLOPEN during May 15-20, 1978, to map the surface character, thickness and extent of the fine-grained.sediment deposit that covers an area 100 x 200 km on the southern New England Continental Shelf. The study area lies between Great South...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1980
John B. Townshend, J.E. Papp, E.A. Sauter, S.P. Tilton
1980, Open-File Report 80-300-J
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
