Timothy J. Durbin, W. F. Hardt
1974, Water-Resources Investigations Report 74-17
The channel of the Mojave Rive'r in California is normally dry and is highly permeable over much of its length, and large quantities of water from natural floodflows in the channel infiltrate through the channel bed to the underlying ground-water body. From 1930 to 1972 only 18 floods at The...
Seismic hazards and land-use planning
Donald R. Nichols, Jane M. Buchanan-Banks
1974, Circular 690
Basic earth-science data are necessary for a realistic assessment of seismic hazards and as a basis for limiting corrective land-use controls only to those areas of greatest hazard. For example, the location, character, and amount of likely displacement and activity of surface faulting can be predicted if detailed geologic maps...

Equilibria of cinnabar, stibnite, and saturated solutions in the system HgS-Sb2S3-Na2S-H2O from 150° to 250°C at 100 bars, with implications concerning ore genesis
R. E. Learned, G. Tunell, F. W. Dickson
1974, Journal of Research of the U.S. Geological Survey (2) 457-466
The common occurrence of cinnabar and stibnite in well-defined districts in the same epithermal environments suggests that similar physiochemical processes are responsible for the genesis of the two minerals; however, cinnabar and stibnite tend to be segregated within these districts and also within individual deposits that contain both minerals. Where...
Estimating the “thickness” of the Boulder Batholith, Montana, from heat-flow and heat-productivity data
Robert I. Tilling
1974, Geology (2) 457-460
Estimates of minimum thickness of the Boulder batholith, computed using the linear relation between heat flow and heat productivity and assuming constant heat productivity with depth, are highly nonspecific. They can vary between about 3 and 20 km, depending on values of surface-rock heat productivity and values of assumed contribution...

Adsorption of MBAS from wastewaters and secondary effluents
David A. Rickert, Joseph V. Hunter
1974, Journal of the Water Pollution Control Federation (46) 911-919
On the basis of adsorption behavior, there seems to be three groups of methylene blue active substances (MBAS) in wastewaters and secondary effluents. The first group is observed at low dosages of activated carbon, contains the bulk of the total MBAS, and is readily adsorbable. The second is noted at...
Estimating survival rates from banding of adult and juvenile birds
Douglas H. Johnson
1974, Journal of Wildlife Management (38) 290-297
The restrictive assumptions required by most available methods for estimating survival probabilities render them unsuitable for analyzing real banding data. A model is proposed which allows survival rates and recovery rates to vary with the calendar year, and also allows juveniles to have rates different from adults. In addition to...
Tectonic evolution of the southern Gulf of Mexico
George W. Moore, Luis Del Castillo
1974, GSA Bulletin (85) 607-618
A detailed magnetic survey in the southern Gulf of Mexico shows subdued irregular magnetic anomalies that are similar in wave length to those attributed to sea-floor spreading on present-day oceanic rises. The small amplitude of these anomalies, about 75γ, would be compatible with an oceanic basalt source at a depth...

Preliminary study of rock alteration in the Catheart Mountain molybdenum-copper deposit, Maine
Robert G. Schmidt
1974, Journal of Research of the U.S. Geological Survey (2) 189-194
Studies of drill cores from the Catheart Mountain molybdenum-copper deposit indicate that the deposit is of the porphyry type. Hydrothermal alteration and sulfide mineralization are probably distributed in complex but systematic alteration zones. Most or all mineralization at Catheart Mountain is in a medium-fine-grained quartz monzonite enclosed within a larger...
