An evaluation of temperature scales for silica diagenesis in diatomaceous sequences including a new approach based on the Miocene Monterey Formation, California
M.A. Keller, C.M. Isaacs
1985, Geo-Marine Letters (5) 31-35
Geologic relations indicate that silica phases transformed in the Monterey Formation in two zones that persist over a narrow depth/temperature range and do not stratigraphically overlap. The wide and overlapping range of reported temperatures of these transformations is mainly a result of the many uncertainties inherent in the different methods...
DISTRIBUTION OF TRACE ELEMENTS IN COAL MINERALS OF SELECTED EASTERN UNITED STATES COALS.
C.A. Palmer, M.-V. Wandless
1985, Conference Paper
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...

NATIONAL WATER INFORMATION SYSTEM OF THE U. S. GEOLOGICAL SURVEY.
Melvin D. Edwards
1985, Conference Paper
National Water Information System (NWIS) has been designed as an interactive, distributed data system. It will integrate the existing, diverse data-processing systems into a common system. It will also provide easier, more flexible use as well as more convenient access and expanded computing, dissemination, and data-analysis capabilities. The NWIS is...

1985, Canadian Mineralogist (23) 233-240
Abhurite is a new mineral species found in blister-like protuberances on the surface of tin ingots submerged at a depth of 35 m in the Red Sea. It forms 1.5 mm diameter hexagonal plates bounded by the negative rhombohedron (0115); is colourless, transparent with opalescent lustre, white streak, hackly fracture,...

A GC-system for the analysis of residual geothermal gases
D.S. Sheppard, A.H. Truesdell
1985, Chromatographia (20) 681-682
The gases evolved from geothermal fields, after condensation of H2O, CO2, H2S and NH3 in caustic solution, contain He, H2, Ar, O2, N2, CH4 and higher hydrocarbons. The analysis for the major components in these residual gas mixtures can be achieved by use of two simple gas chromatographs in parallel,...

1985, Geological Society of America Bulletin (96) 1493-1507
The Ammonoosuc Volcanics and equivalent rocks of Ordovician age are exposed in the Oliverian domes along the Bronson Hill anti-clinorium (BHA) between northern New Hampshire and southern Connecticut. In western New Hampshire and adjacent Vermont and Massachusetts, the Ammonoosuc lithology consists of a...

Managing mapping data using commercial data base management software.
A.A. Elassal
1985, Photogrammetric Engineering and Remote Sensing (51) 1133-1136
Electronic computers are involved in almost every aspect of the map making process. This involvement has become so thorough that it is practically impossible to find a recently developed process or device in the mapping field which does not employ digital processing in some form or another. This trend, which...
Chloride flux out of Yellowstone National Park
D. R. Norton, I. Friedman
1985, Journal of Volcanology and Geothermal Research (26) 231-250
Monitoring of the chloride concentration, electrical conductivity, and discharge was carried out for the four major rivers of Yellowstone National Park from September 1982 to January 1984. Chloride flux out of the Park was determined from the measured values of chloride concentration and discharge. The annual chloride flux from the...
Ring distributions in alkali- and alkaline-earth aluminosilicate framework glasses- A raman spectroscopic study
S.K. Sharma, J.A. Philpotts, D.W. Matson
1985, Journal of Non-Crystalline Solids (71) 403-410
Raman spectra of crystalline polymorphs of a number of tectosilicate minerals having various sizes of smallest rings of TO4 tetrahedra (T = Si, Al) have been investigated to identify the bands that are sensitive indicators of the smallest rings in the network. The information obtained from the Raman spectra of tectosilicate...
Interpretation with a Donnan-based concept of the influence of simple salt concentration on the apparent binding of divalent ions to the polyelectrolytes polystyrenesulfonate and dextran sulfate
J.A. Marinsky, Robert F. Baldwin, M.M. Reddy
1985, Journal of Physical Chemistry (89) 5303-5307
It has been shown that the apparent enhancement of divalent metal ion binding to polyions such as polystyrenesulfonate (PSS) and dextran sulfate (DS) by decreasing the ionic strength of these mixed counterion systems (M2+, M+, X-, polyion) can be anticipated with the Donnan-based model developed by one of us (J.A.M.)....
Geology of the Silsilah ring complex, and associated tin mineralization, Kingdom of Saudi Arabia - a synopsis.
du Bray
1985, American Mineralogist (70) 1075-1086
A tin greisen deposit is associated with an alkali-feldspar granite that forms part of a ring complex at Jabal as Silsilah. The petrological and geochemical characteristics of the Fawwarah alkali-feldspar granite resemble those of granites located elsewhere that are also associated with deposits of Sn, W and rare metals. The...

Gary James H., editor(s)
1985, Conference Paper, Oil Shale Symposium Proceedings
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)...
A uniform technique for flood frequency analysis.
W.O. Thomas Jr.
1985, Journal of Water Resources Planning and Management (111) 321-337
This uniform technique consisted of fitting the logarithms of annual peak discharges to a Pearson Type III distribution using the method of moments. The objective was to adopt a consistent approach for the estimation of floodflow frequencies that could be used in computing average annual flood losses for project evaluation....

Paragenesis and tectonic significance of base and precious metal occurrences along the San Andreas fault at Point Delgada, California
R. J. McLaughlin, D. H. Sorg, J. L. Morton, T. G. Theodore, C.E. Meyer, M.H. Delevaux
1985, Economic Geology (80) 344-359
Studies of sulfide vein mineralization at Point Delgada, California, suggest that the mineralizing process was intimately associated with the San Andreas fault system and/or plate-margin tectonism. The deposits occur along north-south to northeast-southwest-trending tension faults that intersect and cross a major northwest-trending fault previously considered to be a major trace...

1985, Economic Geology (80) 2136-2148
The tectonic setting comprising the West Shasta mining district has often been compared with that of primitive island arcs. Concentrations of uranium, thorium, and lead and lead isotope compositions were determined for Devonian ores and rocks of the West Shasta district, eastern Klamath Mountains, California, to help evaluate the tectonic...
