Variation in surface elevation of the nisqually glacier Mt. Rainier, Washington
A. Johnson
1960, International Association of Scientific Hydrology - Bulletin (5) 54-60
Variation in surface elevations of the Nisqually Glacier has been recorded since 1942 by the annual measurement of three profiles across the glacier, designated as nos. 1, 2, and 3, located 0.5, 1.0, and 1.7 miles respectively from the terminus, at approximate mean elevations of 5,250,6,000, and 6,800 feet. A fourth...
Montana earthquakes noted in pennsylvania mine‐water pools
W.B. Hopkins, T.A. Simpson
1960, Eos, Transactions, American Geophysical Union (41) 435-436
A recent paper by daCosta [1959] reported water‐level fluctuations caused by the Montana earthquake of August 18, 1959, and mentioned the fluctuations registered in three mine‐water pools of the Northern anthracite field in northeastern Pennsylvania, ten miles north of Wilkes‐Barre. This paper will discuss the water‐level phenomena of these pools in more detail. Most...
Chemical equilibrium diagrams for ground-water systems/les graphiques de l'équilibre chimique pour les systèmes des eaux souterrainnes
J.D. Hem
1960, International Association of Scientific Hydrology - Bulletin (5) 45-53
Chemical equilibrium in water in contact with calcite is expressed by means of a pH grid overlay on a log-log plot of activities of bicarbonate vs. calcium ions. Solubility of ferrous iron and the solid-phase minerals that would be stable in a solution containing activities of 10 ppm of sulfate...
Mapping mean areal precipitation
D.R. Dawdy, W. B. Langbein
1960, International Association of Scientific Hydrology - Bulletin (5) 16-23
A method is presented for using point mean precipitation data to estimate areal values in regions of high relief. Variation of precipitation with altitude is determined. Local anomalies from this relationship are mapped, and lines of equal anomaly are drawn. By use of the mean relation corrected for the local anomaly, the mean precipitation at...
Extract ability of humic acid from coalified logs as a guide to temperatures in colorado plateau sediments
Irving A. Breger, J.C. Chandler
1960, Economic Geology (55) 1039-1047
Coalified logs in Triassic and Jurassic sediments of the Colorado Plateau have been exposed to alkaline ground water. Extraction of humic acids under such conditions is temperature dependent. Study of residual humic acids in a suite of coalified logs has indicated that temperatures up to but not over 120° C prevailed in the sediments. This maximum temperature corresponds with that...
The chief oxide-burgin area discoveries, East Tintic district, Utah; A case history
J.B. Bush, D.R. Cook, T. S. Lovering, H. T. Morris
1960, Economic Geology (55) 1116-1147
The Burgin shaft is in the Chief Oxide area of the E. Tintic district, Utah, and is about a mile E. of any previously known ore bodies; workings from it are currently developing a substantial amount of commercial Pb-Zn ore in several blind ore bodies...
Review of paleomagnetism
Allan Cox, Richard R. Doell
1960, GSA Bulletin (71) 645-768
This review is an attempt to bring together and discuss relevant information concerning the magnetization of rocks, especially that having paleomagnetic significance. All paleomagnetic measurements available to the authors are here compiled and evaluated, with a key to the summary table and illustrations in English and Russian. The principles upon...
Deposits of the manganese oxides
Richard G. Petersen
1960, Economic Geology (55) 1-55
One of the problems of the wartime program of studies of domestic manganese deposits concerned the identification of, and modes of origin of the manganese oxide minerals. Of the hundreds of specimens of the oxides collected in the United States, the minerals of about 250...
Stratigraphic and geotectonic relationships in northern Vermont and southern Quebec
W.M. Cady
1960, Economic Geology (71) 531-576
Stratified rocks of early and middle Paleozoic age form a belt of northeast-trending anticlinoria and synclinoria of middle Paleozoic age, in northern Vermont and adjacent parts of southern Quebec. The foreland margin of this belt, in the Champlain and St. Lawrence valleys to the west, is cut by eastward-dipping thrust faults of...
Geobotanical map of the U.S.S.R.
V.B. Sochava
1960, International Geology Review (2) 311-321
A newly compiled geobotanical map of the U.S.S.R. scale 1:4,000,000 is described. Two hundred and ten categories of vegetation are mapped, classified under 15 major groups. The relation of the mapped vegetation units to climate, soil, ground condition (permafrost), watersheds, and major geomorphic features is emphasized....
Part I, the development of the method
I. Friedman, R. Smith
1960, American Antiquity (25) 476-493
A freshly exposed surface of obsidian will take up water from the atmosphere to form a hydrated surface layer. This layer has a different density and refractive index than does the remainder of the obsidian. Using special techniques, a thin section of the obsidian cut at right angles to the...
Ground-water hydrology and glacial geology of the Kalamazoo area, Michigan
Morris Deutsch, K.E. Vanlier, P.R. Giroux
1960, Progress Report 23
The Kalamazoo report area includes about 150 square miles of Kalamazoo County, Mich. The area is principally one of industry and commerce, although agriculture also is of considerable importance. It has a moderate and humid climate and lies within the Lake Michigan “snow belt”. Precipitation averages about 35 inches per...
