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....

Floods in the Raccoon River basin, Iowa
Albert J. Heinitz
1980, Open-File Report 80-162
Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains requires information on floods. This report provides information on flood stages and discharges, flood magnitude and frequency, bench mark data, and flood profiles for the Raccoon River and some of its tributaries. It covers...

Seismic refraction data for shots recorded in the Coso Range, California, October 1976
A. W. Walter, Craig S. Weaver
1980, Open-File Report 80-186
The Coso Range lies in the southwest corner of the Basin and Range province, east of the Sierra Nevada and north of the Garlock Fault. The range, circular in form, is covered by a thin sequence of late-cenozoic volcanics which overlie highly fractured crystalline basement, similar in composition to the...
Spectrographic and chemical analyses of whole-rock and insoluble-residue samples, Rolla 1° by 2° quadrangle, Missouri: Drill hole No. 22

1980, Open-File Report 80-701
Geochemical studies of the Rolla, Mo., 1° x 2° quadrangle were begun in 1977 as part of a joint multidisciplinary study of the quadrangle by the U.S. Geological Survey and the Division of Geology and Land Survey, Missouri Department of Natural Resources. The study is to access the mineral-resource potential...

1980, Open-File Report 80-1190
At 39 cross sections in a 3.3-kilometer reach of East Fork River Wyo., bed elevations were measured daily during a month-long period that included the peak snowmelt runoff. Elevations were measured at less frequent intervals for a week before and several weeks after peak runoff. Considerable scour and fill was...
Mathematical model of the Tesuque aquifer system underlying Pojoaque River basin and vicinity, New Mexico
Glenn A. Hearne
1980, Open-File Report 80-1023
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...

Reconnaissance of ground-water resources in the vicinity of Gunnison and Crested Butte, West-central Colorado
T.F. Giles
1980, Open-File Report 80-12
Hydrologic data was collected in the Gunnison-Crested Butte area , Colo., to determine the availability and chemical quality of groundwater. Parts of the area have undergone rapid population growth in recent years due to an increase of winter sports activities. This rapid growth has resulted in a demand for additional...
