PROBLEMS AND METHODOLOGY OF THE PETROLOGIC ANALYSIS OF COAL FACIES.
Edward C.T. Chao
1983, Conference Paper
This condensed synthesis gives a broad outline of the methodology of coal facies analysis, procedures for constructing sedimentation and geochemical formation curves, and micro- and macrostratigraphic analysis. The hypothetical coal bed profile has a 3-fold cycle of material characteristics. Based on studies of other similar profiles of the same coal...
Isotopic studies of mariposite-bearing rocks from the south- central Mother Lode, California.
R. W. Kistler, F. C. W. Dodge, M.L. Silberman
1983, California Geology (36) 201-203
Gold-bearing vein formation in the Mother Lode belt of the study area apparently occurred during the Early Cretaceous between 127 and 108 m.y. B.P. The hydrothermal fluids that carried the gold precipitated quartz and mariposite at approx 320oC, similar to the T of precipitation of gold-bearing quartz veins in the...
Helium isotopic variations in volcanic rocks from Loihi Seamount and the Island of Hawaii
M.D. Kurz, W.J. Jenkins, S.R. Hart, David Clague
1983, Earth and Planetary Science Letters (66) 388-406
Helium isotopic ratios ranging from 20 to 32 times the atmospheric 3He 4He(RA) have been observed in a suite of 15 basaltic glasses from the Loihi Seamount. These ratios, which are up to four times higher than those of MORB glasses and more than twice those of nearby Kilauea,...
Heat capacty, relative enthalpy, and calorimetric entropy of silicate minerals: an empirical method of prediction.
G.R. Robinson Jr., J.L. Haas Jr.
1983, American Mineralogist (68) 541-553
Through the evaluation of experimental calorimetric data and estimates of the molar isobaric heat capacities, relative enthalpies and entropies of constituent oxides, a procedure for predicting the thermodynamic properties of silicates is developed. Estimates of the accuracy and precision of the technique and examples of its application are also presented....
PROPOSED SPECIFICATIONS FOR INERTIAL SURVEYING.
William H. Chapman
1983, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
The purpose of this paper is to continue the movement toward placing inertial surveying instruments in the toolbox of the geodetic surveyor. A set of specifications is proposed for performing horizontal geodetic surveys with inertial instruments that will meet the Federal Geodetic Control Committee (FGCC) second- and third-order standards. These...
Geochemistry of the Chattanooga shale, Dekalb County, central Tennessee.
J.S. Leventhal, Paul H. Briggs, J.W. Baker
1983, Southeastern Geology (24) 101-116
This Upper Devonian shale is of interest because of its unusual enrichment in trace elements, especially U; a new chemical analysis for major, minor and trace elements is presented. Stable isotopes of carbon (organic) show delta 13C approx -29per mille and for total sulphur show -21 to -27per mille delta...
LITHOLOGIC MAPPING USING LANDSAT THEMATIC MAPPER DATA.
M. H. Podwysocki, J.W. Salisbury, O. D. Jones, D.L. Mimms
1983, Conference Paper
The paper is in abstract form. It discusses the Landsat-4 Thematic Mapper (TM), with its new near infrared bands centered at 1. 65 mu m and 2. 20 mu m and spatial resolution of 30 m, which has been used to distinguish rocks containing minerals having ferric-iron absorption bands in...
Mapping the earthquake hazards of the Los Angeles region.
J. I. Ziony, J. C. Tinsley
1983, Earthquake Information Bulletin (USGS) (15) 134-141
Discusses examples of fault, shaking and ground-failure hazards taken from recent studies of the Los Angeles region. These should provide an improved basis for delineating geographic variations in local earthquake hazards. -M.Barrett...
Selective preservation and origin of petroleum-forming aquatic kerogen
Patrick G. Hatcher, E.C. Spiker, N.M. Szeverenyi, G.E. Maciel
1983, Nature (305) 498-501
Studies of a marine algal sapropel from Mangrove Lake, Bermuda, by 13C NMR and stable carbon isotopic methods show that precursors of aquatic kerogen (insoluble, macromolecular, paraffinic humic substances) are primary components of algae and possibly associated bacteria and that these substances survive microbial decomposition and are selectively preserved during...
SOME NEW PROCESSING TECHNIQUES FOR THE IMPERIAL VALLEY 1979 AFTERSHOCKS.
A. Gerald Brady
Chung Riley M.Lew H.S.Kovacs William D., editor(s)
1983, Conference Paper, National Bureau of Standards, Special Publication
This paper describes some of the features of the latest processing improvements that the U. S. Geological Survey (USGS) is currently applying to strong-motion accelerograms from the national network of permanent stations. At the same time it introduces the application of this processing to the set of Imperial Valley aftershocks...
Geology of the Devonian black shales of the Appalachian basin
J.B. Roen
1983, Conference Paper, Preprints Symposia
Black shales of Devonian age in the Appalachian basin are a unique rock sequence. The high content of organic matter, which imparts the characteristic lithology, has for years attracted considerable interest in the shales as a possible source of energy. Concurrent with periodic and varied economic exploitations of the black...
ROLES OF REMOTE SENSING AND CARTOGRAPHY IN THE USGS NATIONAL MAPPING DIVISION.
Rupert B. Southard, John W. Salisbury
1983, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
The inseparable roles of remote sensing and photogrammetry have been recognized to be consistent with the aims and interests of the American Society of Photogrammetry. In particular, spatial data storage, data merging and manipulation methods and other techniques originally developed for remote sensing applications also have applications for digital cartography....
Use of nearshore and estuarine areas by gray whales (Eschrichtius robustus) in the eastern Bering Sea
Robert E. Gill Jr., John D. Hall
1983, Arctic (36) 275-281
During spring aerial surveys of the coast of the southeastern Bering Sea significant numbers of gray whales were seen in nearshore waters along the north side of the Alaska Peninsula. Many (50-80%) of these animals were observed surfacing with mud trails or lying on their sides, characteristics both associated with...

Estuaries along the north side of the Alaska Peninsula provide essential habitat for most of the American population of Emperor Goose (Chen canagica) during migration (Petersen and Gill 1982). Most of the population passes through Nelson Lagoon in spring and fall, with over 40,000 birds recorded there (Gill et al...

The fledging of common and thick-billed murres on Middleton Island, Alaska
Scott A. Hatch
1983, Journal of Field Ornithology (54) 266-274
Three species of alcids, Common and Thick-billed murres (Uria aalge and U. lomvia) and the Razorbill (Alca torda), have post-hatching developmental patterns intermediate to precocial and semi-precocial modes (Sealy 1973). The young leave their cliff nest sites at about one quarter of adult weight and complete their growth at sea....
