DATA ACQUISITION AND APPLICATIONS OF SIDE-LOOKING AIRBORNE RADAR IN THE U. S. GEOLOGICAL SURVEY.
The Side-Looking Airborne Radar (SLAR) program encompasses a multi-discipline effort involving geologists, hydrologists, engineers, geographers, and cartographers of the U. S. Geological Survey (USGS). Since the program began in 1980, more than 520,000 square miles of aerial coverage of SLAR data in the conterminous United States and Alaska have been acquired or contracted for acquisition. The Geo

DISTRIBUTION OF TRACE ELEMENTS IN COAL MINERALS OF SELECTED EASTERN UNITED STATES COALS.
The association of 34 elements with minerals found in coal was determined by a combination of analytical techniques on size and density fractions of low-temperature ash (LTA). Instrumental neutron activation analysis was used to determine the concentrations of the elements, and X-ray diffraction analysis, scanning electron microscopy, and scanning transmission electron microscopy were used to iden

Earthquake hazards to domestic water distribution systems in Salt Lake County, Utah
A magnitude-7. 5 earthquake occurring along the central portion of the Wasatch Fault, Utah, may cause significant damage to Salt Lake County's domestic water system. This system is composed of water treatment plants, aqueducts, distribution mains, and other facilities that are vulnerable to ground shaking, liquefaction, fault movement, and slope failures. Recent investigations into surface faultin

EARTHQUAKE PERFORMANCE OF A BRIDGE DECK AND ABUTMENT.
During the 24 April 1984 Morgan Hill Earthquake (M equals 6. 1), 15 channels of acceleration records were obtained at the site of the I-280-680/US 101 interchange 12 km west of the epicenter. These records include free field measurements as well as the acceleration response at one of the supporting column bases, and at three locations in one of the spans of the three-span continuous post-tensioned

EEZ-SCAN: A U. S. GEOLOGICAL SURVEY SEA-FLOOR IMAGING PROGRAM USING THE GLORIA SIDE-SCAN SONAR SYSTEM.
The U. S. Geological Survey initiated Program EEZ-SCAN in April 1984 in cooperation with the Institute of Oceanographic Sciences (IOS) of the United Kingdom to map the U. S. Exclusive Economic Zone (EEZ) at reconnaissance scale as a first effort to develop a geologic understanding of the new national territory. GLORIA*, a unique side-scan sonar system capable of mapping over 27,000 sq. km per day,

EFFECT OF SANTA ROSA LAKE ON GROUND WATER FLOW TO THE PECOS RIVER, NEW MEXICO.
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa Rosa Lake has caused changes in the ground water flow system, which may cause changes in the streamflow of the Pecos River that cannot be detected at the present streamflow-gaging stations, which are used to admi

EFFECT OF TEMPERATURE ON THE SORPTION OF CHELATED RADIONUCLIDES.
Temperature effects in the near-field radioactive waste disposal environment can result in changes in the adsorptive capacity and character of the substrate and the chemistry of the reacting fluids. This work examines the effect of temperature on 1) the kinetics of radionuclide sorption onto clays from 25 degree -75 degree C and 2) the degradation and metal-binding ability of two organic complexin

EFFECTS OF LITHOLOGY ON TELEVIEWER-LOG QUALITY AND FRACTURE INTERPRETATION.
Representative televiewer logs illustrating natural fractures in such common rock types as granite, gabbro, basalt, schist, sandstone, limestone and shale are presented in addition to photographs of the same fractures in core samples. These examples demonstrate the many difficulties in recognizing fractures on televiewer logs compared to fractures in logs because of the vertical scale distortion o

ELECTROCHEMICAL PROPERTIES OF ROCKS AND MINERALS.
Many phenomena and processes in the earth sciences are a result of the electrochemical properties of rocks and minerals. Examples include formation of mineral deposits and petroleum reservoirs control of drilling muds, and success or failure of toxic waste isolation barriers. Such phenomena can be observed at a distance using geophysical techniques to measure various electrical properties of the e

ESTIMATE OF WORLD HEAVY CRUDE OIL AND NATURAL BITUMEN RESOURCES.
The quantity of heavy hydrocarbons - heavy crude oil and natural bitumens - known or surmised to be present in the earth is large. The total is estimated to fall in the range of 5,879,712-5,942,139 million barrels. The portion of this that may ultimately prove recoverable is small, perhaps on the order of 500,000 million barrels of heavy crude oil and 200,000 million barrels of bitumen.

EVALUATION OF THE EFFECTS OF WEATHERING ON A 50-YEAR OLD RETORTED OIL-SHALE WASTE PILE, RULISON EXPERIMENTAL RETORT, COLORADO.
An oil-shale mine and experimental retort were operated near Rulison, Colorado by the U. S. Bureau of Mines from 1926 to 1929. Samples from seven drill cores from a retorted oil-shale waste pile were analyzed to determine 1) the chemical and mineral composition of the retorted oil shale and 2) variations in the composition that could be attributed to weathering. Unweathered, freshly-mined samples
