Jon J. Connor, John R. Keith, Barbara M. Anderson
1976, Journal of Research of the U.S. Geological Survey (4) 49-59
A reconnaissance study of 28 trace metals in samples of surface soil (0-2.5 cm deep), subsurface soil (15-20 cm deep), and big sagebrush (Artemisia tridentata) that were collected from the Powder River Basin in Wyoming and Montana indicates that little variation occurs in nature at scales greater than about 35...
Age and origin of the Darrough Felsite, southern Toiyabe Range, Nevada
R. C. Speed, E.H. McKee
1976, Journal of Research of the U.S. Geological Survey (4) 75-81
The name Darrough Felsite was originally assigned to a body of fine-grained quartzofeldspathic igneous rock probably greater than 3 km thick that is exposed continuously over 100 km2 in the southern Toiyabe Range of central Nevada. The Darrough was supposed to consist mostly of intrusive rocks of probable Permian age....

Ronald L. Malcolm
1976, Journal of Research of the U.S. Geological Survey (4) 37-40
A detailed procedure incorporating centrifugation, pressure filtration, dialysis, resin exchange, and freeze drying is given for the extraction and purification of fulvic and humic acids from soils and sediments. By use of the procedure humic acids have been prepared which have less than 0.22 percent ash. The isolation of relatively...
Behavior of trace elements during magmatic processes - A summary of theoretical models and their applications
Joseph G. Arth
1976, Journal of Research of the U.S. Geological Survey (4) 41-47
Progress in understanding the behavior of trace elements during the processes that produce igneous rocks has been made possible by the parallel development of theoretical models to describe that behavior and analytical techniques that permit precise measurement of trace-element concentrations in igneous rocks and minerals. The result of this progress...
The source of hydrothermal solutions at Puerto Maunabo and its bearing on the base-metal-potassium feldspar association in Puerto Rico
M. H. Pease Jr.
1976, Journal of Research of the U.S. Geological Survey (4) 61-65
A quartz oligoclase porphyry exposed near Puerto Maunabo may provide evidence to further our understanding of the base-metal-potassium feldspar association known to occur in many of the porphyry-type copper deposits of Puerto Rico. The porphyry appears to be a magmatic differentiate on the border of the San Lorenzo batholith that...

Land subsidence and aquifer-system compaction in the San Jacinto Valley, Riverside County, California - A progress report
Ben Elder Lofgren
1976, Journal of Research of the U.S. Geological Survey (4) 9-18
Widespread subsidence continues in the San Jacinto structural trough as water levels continue to decline. Subsidence is due principally to the compaction of water-bearing deposits as effective stresses are increased by artesian-head decline. Other possible contributory causes of subsidence are (1) local or regional tectonic adjustments and graben downfaulting, (2)...
