Intrusions and intrusive complexes in an ophiolite near San Luis Obispo; a chemical and petrologic study
Jane E. Nielson Pike
1980, Open-File Report 80-185
The San Luis Obispo ophiolite is a sequence of mafic and ultramafic rocks that lie as a thrust-like slice on top of Franciscan melange in the southern California Coast Range. The ophiolite comprises the classic Steinmann Trinity of basal serpentinized ultramafic rocks overlain sequentially by spilitized pillow lavas and cherts....

Annotated bibliography of spectrophotometric studies in the system U-Fe-Se-S-O-H, 1967-78
K.A. McGee, A. Jefferson Sutton, Nicholas John Susak
1980, Open-File Report 80-199
Preparation of this bibliography was originally begun to supply background information on previous ultraviolet and visible spectrophotometric studies on various chemical species thought to be important in the formation of sedimentary uranium deposits; we also thought that preparing the bibliography would help direct experimental efforts to determine the association of...

Mekometer measurements in the Imperial Valley, California, 1980
Ronald G. Mason, C.N. Crook, Perry Rowley Wood
1980, Open-File Report 81-1141
During a six-week period in the Spring of 1980, approximately seven months after the October 15, 1979 earthquake, parts of the Imperial Valley mekometer network (Fig. 1) were re-measured for comparison with measurements made during the twelve months preceding the earthquake and the six weeks following it. The purpose was...
Hole-to-surface resistivity measurements at Salt Valley, Utah
Jeffrey J. Daniels, James H. Scott
1980, Open-File Report 80-981
Evaporites are an important potential medium for the storage of radioactive wastes. In order to ascertain the viability of a proposed waste isolation site, it is necessary to study its geology without extensive drilling that might destroy its structural integrity. Hole-to-surface and hole-to-hole geophysical measurements can be useful in supplementing...

Geophysical-geological analysis of Fairfax County, Virginia
David L. Daniels
1980, Open-File Report 80-1165
Aeromagnetic, aeroradioactivity, and gravity surveys of Fairfax County, Virginia, are interpreted with the aid of existing geologic data and local geophysical measurements. Highly magnetic metasedimentary rocks of the Peters Creek Schist and Sykesville Formation produce most of the magnetic anomalies of Fairfax County. In contrast, the granitoid rocks of the...

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...

Ground-water appraisal of sand plains in Benton, Sherburne, Stearns, and Wright counties, central Minnesota

1980, Open-File Report 80-1285
Surficial-sand aquifers in 960 square miles of central Minnesota have been studied to determine the occurrence, availability, and suitability of the surficial aquifer as a source of water. The aquifer is being increasingly developed for irrigation. During the drought of 1976, nearly 24,000 acre-feet of ground water was withdrawn for irrigation,...

Rates of sedimentation calculated from analyses of 210Pb activities in cores from Upper Klamath Lake and Lake Euwana (Klamath County, Ore.) indicate that the lakes, whose mean depths are 2.4 m, are filling at approximately 3.5 mm/yr. In Upper Klamath Lake, average accumulation rates range from 0.9 mm/yr at a...
