Surface and aircraft measurements were obtained during all seasons using a wide variety of active and passive microwave sensors. The surface program obtained passive microwave...
Dislocation substructure of mantle-derived olivine as revealed by selective chemical etching and transmission electron microscopy
S. H. Kirby, M.W. Wegner
1978, Physics and Chemistry of Minerals (3) 309-330
Cleaved and mechanically polished surfaces of olivine from peridotite xenoliths from San Carlos, Arizona, were chemically etched using the techniques of Wegner and Christie (1974). Dislocation etch pits are produced on all surface orientations and they tend to be preferentially aligned along the traces of subgrain boundaries, which are approximately...
Identification and significance of accessory minerals from a bituminous coal
R. B. Finkelman, R.W. Stanton
1978, Fuel (57) 763-768
A scanning electron microscope (SEM) has been used to study the in situ accessory minerals in polished blocks and pellets of petrographically analysed samples of the Waynesburg coal (hvb). Individual grains from the low-temperature ash (LTA) of the same coal were also studied. The visual resolution of the SEM permitted the detection...
Geodimeter measurements and the Southern California uplift
W.H. Prescott, J.C. Savage
1978, Earthquake Information Bulletin (USGS) (10) 131-135
Modern surveying instruments, such as geodimeters, are capable of measuring distances in the range of 1 to 30 kilometers with remarkable precision. Indeed, the present limitation upon the precision of measurement is not the resolution of the instruments themselves but rather the uncertainty introduced by variations in the velocity of...
How often will earthquakes recur on the San Andreas Fault?
R. E. Wallace
1978, Earthquake Information Bulletin (USGS) (10) 76-81
The relationship between magnitude and abundance of earthquakes, called a recurrence curve, has been derived for many regions of the world from seismographic records. AS an example, Clarence Allen and his associates at the California Institute of Technology have obtained recurrence rates for the southern California region by incorporating data...
Applications of the VLF induction method for studying some volcanic processes of Kilauea volcano, Hawaii
C.J. Zablocki
1978, Journal of Volcanology and Geothermal Research (3) 155-195
The very low-frequency (VLF) induction method has found exceptional utility in studying various volcanic processes of Kilauea volcano, Hawaii because: (1) significant anomalies result exclusively from ionically conductive magma or still-hot intrusions (> 800??C) and the attendant electrolytically conductive hot groundwater; (2) basalt flows forming the bulk of Kilauea have...
Geomagnetic paleointensities from radiocarbon‐dated lava flows on Hawaii and the question of the Pacific nondipole low
Robert S. Coe, Sherman Gromme, Edward A. Mankinen
1978, Journal of Geophysical Research B: Solid Earth (83) 1740-1756
Radiocarbon ages have been published for nine basaltic lava flows on the island of Hawaii; the ages range from 2600 to somewhat older than 17,900 years B.P. By using the Thelliers' method in vacuum, geomagnetic paleointensity values were obtained from eight of the lavas; the ninth proved unsuitable. The paleointensities...
Field expectations and the determination of wildcat drilling
Emil D. Attanasi, L. J. Drew
1977, Southern Economic Journal (44) 53-67
There is currently some dissatisfaction with macroeconomic approaches to modeling the supply of domestic crude oil. One problem that has been pointed out is that the estimated supply responses of new discoveries brought about by price increases appear to be unrealistically high. Because data  frequently  used in these models  are...

Combined use of digital aquifer models and field base-flow data to identify recharge-leakage areas of artesian aquifers
Richard H. Johnston, P. Patrick Leahy
1977, Journal of Research of the U.S. Geological Survey (5) 491-496
As a result of continuous pumping since the 1890's, a regional cone of depression encompassing 363 km2 has developed within the artesian Miocene Cheswold aquifer at Dover, Del. The aquifer is not being recharged significantly by leakage near the center of the cone, nor is major recharge induced in the...
High-resolution gamma-ray spectrometry in uranium exploration
Robert M. Moxham, Allan B. Tanner
1977, Journal of Research of the U.S. Geological Survey (5) 783-785
Sedimentary-type uranium deposits accumulate at favorable sites along a migration path which may be kilometers in length. Their source is a large volume of rock from which the uranium has been leached. The geochemical mobilities and half lives of uranium and its daughter products vary widely so that they are...
Application of linear statistical models of earthquake magnitude versus fault length in estimating maximum expectable earthquakes
Robert K. Mark
1977, Geology (5) 464-466
Correlation or linear regression estimates of earthquake magnitude from data on historical magnitude and length of surface rupture should be based upon the correct regression. For example, the regression of magnitude on the logarithm of the length of surface rupture L can be used to estimate magnitude, but the regression of log L on...

S. H. Kirby
1977, Pure and Applied Geophysics PAGEOPH (115) 245-258
The experimental flow data for rocks and minerals are reviewed and found to fit a law of the form {Mathematical expression} where {Mathematical expression} This law reduces to the familiar power-law stress dependency at low stress and to an exponential stress dependency at high stress. Using the material flow law...
Fluid inclusion geothermometry
C.G. Cunningham
1977, Geologische Rundschau (66) 1-9
Fluid inclusions trapped within crystals either during growth or at a later time provide many clues to the histories of rocks and ores. Estimates of fluid-inclusion homogenization temperature and density can be obtained using a petrographic microscope with thin sections, and they can be refined using heating and freezing stages....
