Geophysical maps and interpretations of the Domeland Wilderness and contiguous Roadless Areas, Kern and Tulare counties, California
Robert C. Jachens
1983, Miscellaneous Field Studies Map 1395-B
Geophysical maps were compiled and constructed from gravity and aeromagnetic surveys of the study area in order to assist the geologic mapping and the mineral resource assessment of the Domeland Wilderness and contiguous roadless areas. The isostatic residual gravity map (fig. 1) primarily reflects lateral density variations within the upper...
Aeromagnetic map and interpretation of geophysical data from the Condrey Mountain Roadless Area, Siskiyou County, California
R.C. Jachens, W.P. Elder
1983, Miscellaneous Field Studies Map 1540-B
The Condrey Mountain Roadless Area lies within the Klamath Mountains geologic province, a province composed of four eastward-dipping imbricate thrust slices or belts consisting predominantly of marine arc-related volcanic and sedimentary rocks, but also including significant amounts of ultramafic and other ophiolitic rocks (Irwin, 1981). From west to east the...
Environmental-stratigraphic cross sections of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and Paleocene Fort Union Formation, Richland and Roosevelt Counties, Montana
R. M. Flores, C.L. Lepp
1983, Miscellaneous Field Studies Map 1554
This study was conducted to determine the stratigraphic, lithofacies, and deopsitional relationships of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and The Paleocene Fort Union Formation. These relationships, shown in sections A-A', B-B', C-C', and D-D', we established form nearly continuous exposures in the Missouri River valley in...
Geologic and aeromagnetic maps and mineral resource potential survey of the Blackjack Springs Wilderness, Vilas County, Wisconsin
Klaus J. Schulz
1983, Miscellaneous Field Studies Map 1592
The mineral resource potential of the Blackjack Springs Wilderness in the Nicolet National Forest, Vilas County, Wisc., was evaluated in 1982.  No bedrock exposures are known in or near the wilderness.  Geophysical data and regional geologic relations suggest that the area consists mostly of recrystallized and deformed mafic volcanic rocks...
Mine and prospect map of the Vermilion Cliffs-Paria Canyon Instant Study Area and adjacent wilderness areas, Coconino County, Arizona, and Kane County, Utah
Michael Lane
1983, Miscellaneous Field Studies Map 1475-C
Vermilion Cliffs-Paria Canyon Instant Study Area and adjacent wilderness areas are mostly in Coconino County Ariz., but extend into Kane County, Utah. The area studied in this report encompasses about 560 mi2 (1,450 km2). The study area includes the established Paria Canyon Primitive and Vermilion Cliffs Natural Areas between U.S....
Mineral resource potential map of the Gee Creek Wilderness, Polk and Monroe counties, Tennessee
Jack B. Epstein, Gertrude C. Gazdik, Paul T. Behum
1983, Miscellaneous Field Studies Map 1474-D
The Gee Creek Wilderness comprises 2,493 acres (nearly 4 square miles) in the Cherokee National Forest, Polk and Monroe Counties, Tennessee, about 4 miles (6 km) southeast of Etowah, Tenn., and about 20 miles northeast of Cleveland, Tenn. All of the surface in the wilderness is in U.S. Government ownership;...
Fortran computer programs to plot and process aquifer pressure and temperature data
J.B. Czarnecki
1983, Water-Resources Investigations Report 83-4051
Two FORTRAN computer programs have been written to process water-well temperature and pressure data recorded automatically by a datalogger on magnetic tape. These programs process the data into tabular and graphical form. Both programs are presented with documentation. Sample plots of temperature versus time, water levels versus time, aquifer pressure...
Projected effects of proposed chloride-control projects on shallow ground water– Preliminary results for the Wichita River basin, Texas
Sergio Garza
1983, Water-Resources Investigations Report 83-4026
The U.S. Army Corps of Engineers' plan to control the natural chloride pollution in the Wichita River basin includes the construction of Truscott Brine Lake on a tributary of the North Wichita River. In connection with the proposed brine lake, the U.S. Geological Survey was requested to: (1) Define the...
Front-tracking model for convective transport in flowing ground water
S. P. Garabedian, Leonard F. Konikow
1983, Water-Resources Investigations Report 83-4034
A finite-difference numerical model that simulates the convective transport of water or tracer particles through porous media is described. It can be applied to one- or two-dimensional problems involving either steady-state or transient flow. The model tracks representative water or tracer particles, initially located along specified lines, as they move...
