Multichannel seismic-reflection data collected in 1980 in the eastern Chukchi Sea
Arthur Grantz, Dennis M. Mann, Steven D. May
1986, Open-File Report 86-405
The U.S. Geological Survey (USGS) collected approximately 2,652 km of 24-channel seismic-reflection data in early September, 1980, over the continental shelf in the eastern Chukchi Sea (Fig. 1). The profiles were collected on the USGS Research Vessel S.P. Lee. The seismic energy source consisted of a tuned array of five...

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...

A model for the plastic flow of landslides
William Z. Savage, William K. Smith
1986, Professional Paper 1385
To further the understanding of the mechanics of landslide flow, we present a model that predicts many of the observed attributes of landslides. The model is based on an integration of the hyperbolic differential equations for stress and velocity fields in a two-dimensional, inclined, semi-infinite half-space of Coulomb plastic material...
