A mineralogical study of the Guanajuato, Mexico, silver ores
Ivan Franklin Wilson, Charles Milton, Joseph Rollins Houston
1975, Open-File Report 75-70
The silver-gold ores now being worked in the Guanajuato, Mexico, mining district consist chiefly of argentite and native gold-silver, with minor amounts of polybasite, pyrargyrite, and some argyrodite, a silver germanium sulfide. With these are always associated galena, sphalerite, chalcopyrite, pyrite, and minor amounts of marcasite. The gangue is generally...

R.E. Taylor
1975, Open-File Report 75-79
Chemical analyses of 4,269 water samples from wells in 66 counties in Texas have been processed into the National Water Data Storage and Retrieval System by the Gulf Coast Hydrogeology Project of the U. S. Geological Survey. More than 65,000 chemical analyses of saline waters produced by oil test and...
Preliminary report on the reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1975, Open-File Report 75-529
Yakutat, situated about 225 miles northwest of Juneau, Alaska, near the shores of the Gulf of Alaska, has a setting that calls for superlatives. Within the Yakutat region are some of the tallest mountains, some of the heaviest snowfalls, and the largest glacier in North America. Between the abrupt mountain...

This statement is a response to questions raised by personnel of the U.S. Forest Service, Lakeview, Oregon, with respect to the possible effects on Lake Abert and its basin if the propos ed Coffeepot Reservoir is built on Chewaucan River. The responses are keyed to paragraphs in a letter of...
Preliminary map of landslide deposits, Denver 1° by 2° Quadrangle, Colorado
Roger B. Colton, Jeffrey A. Holligan, Larry W. Anderson
1975, Miscellaneous Field Studies Map 705
Areas inferred to be underlain by landslide deposits resulting from landsliding, avalanching, block gliding, debris sliding or flowing, earthflows, mudflows, rocksliding, rockfalls, rotational slides, slab or flake sliding, slumping, talus accumulation, and translational sliding. Rock glacier deposits, colluvium, and solifluction deposits are included in some areas. Some till is mapped...

Water resources of Wisconsin — Upper Wisconsin River basin
Edward L. Oakes, R. D. Cotter
1975, Hydrologic Atlas 536
Runoff is the water in a river or stream that results from precipitation falling on the drainage basin. It is the net discharge into the stream from surface-water and ground-water sources with losses occurring from evapotranspiration and other consumptive uses. Runoff can be expressed by a variety of numerical values,...

Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults
Roger D. Borcherdt, James F. Gibbs, Kenneth R. Lajoie
1975, Miscellaneous Field Studies Map 709
This map shows maximum earthquake intensity predicted at specific sites using the empirical relations derived from the reliable 1906 intensity data (figs. 3 and 4; see text). The numbers 4-0 correspond to letters A-E, respectively, of the San Francisco intensity scale. The predicted intensity value shown for each site is...
