Geology and ore deposits of the central York Mountains, western Seward Peninsula, Alaska
C.L. Sainsbury
1965, Open-File Report 65-142
In the central York Mountains, carbonate rocks of Lower and Middle Ordovician age and aggregating at least 8,000 feet thick are thrust northward over slate and argillaceous limestone of pre-Ordovician age which were intruded by gabbro in pre-Ordovician time. Normal faults of four distinct systems cut the thrust plates, and...
Geology of the Romanzof Mountains, Brooks Range, northeastern Alaska
Edward G. Sable
1965, Open-File Report 65-141
This remote 700 square mile area in the Brooks Range is topographically rugged and geologically diverse; it contains a granitic pluton, low-grade metamorphic rocks, sedimentary rocks, and mafic igneous rocks, as well as glacial features.Rocks of sedimentary origin include from oldest to youngest:1.Neruokpuk Formation Middle and Upper Devonian(?), more than...
Fluvial sediment of the Mississippi River at St. Louis, Missouri
Paul Robert Jordan
1965, Water Supply Paper 1802
An investigation of the fluvial sediment of the Mississippi River at St. Louis, Mo., was begun in 1948. Most data have been obtained only to determine the daily suspended-sediment discharge and the particle-size distribution of suspended sediment and bed material, but a few data have been obtained to study the...
Variations in chemical character of water in the Englishtown Formation, New Jersey
Paul R. Seaber
1965, Professional Paper 498-B
This investigation describes the variations in the chemical character of the water in the Englishtown Formation of Late Cretaceous age in the Atlantic Coastal Plain of New Jersey, and demonstrates the application of the concept of hydrochemical mapping to the study and evaluation of water-bearing materials. The chemistry of ground water...
Resource understanding: a challenge to aerial methods
Stewart L. Udall
1965, Photogrammetric Engineering (31) 63-75
Aerial survey methods are speeding acquisition of survey data needed to provide and manage the nation's resources. These methods have been applied to topographic mapping for a number of years and the record clearly shows their advantages in terms of cost and speed in contrast to the ground methods that...
Water resources data for Indiana, 1965
Water Resources Division, U.S. Geological Survey
1965, Water Data Report IN-65-1
The surface-water records for the 1965 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the...
Titanium dioxide in pyroclastic layers from volcanoes in the Cascade Range
G.K. Czamanske, S.C. Porter
1965, Science (150) 1022-1025
Rapid determinations of titanium dioxide have been made by x-ray emission techniques to evaluate the potentiality of using the TiO2 content of samples for checking field correlations and assisting in identification of pyroclastic units from Cascade volcanoes. Preliminary data suggest that the two most widespread units have characteristic ranges of TiO2 content...
The drill‐stem test: The petroleum industry's deep‐well pumping test
J.D. Bredehoeft
1965, Groundwater (3) 31-36
Drill‐stem tests provide the petroleum industry information on three critical properties of subsurface formations —pressure head, permeability, and water chemistry –that the ground‐water hydrologist also seeks in making pumping tests of water wells. As it is increasingly necessary to study the hydraulic and geochemical properties of deep‐lying rocks in order to understand the behavior of ground water,...
Gamma-ray spectrometer studies of hydro-thermally altered rocks
R.M. Moxham, R.S. Foote, C. M. Bunker
1965, Economic Geology (60) 653-671
The uranium, thorium, and potassium content of hydrothermally altered rocks in the vicinity of several copper and copper-lead-zinc deposits in Arizona was determined by chemical analysis. Potassium in the more intensely altered zones is about twice that in unaltered areas. There is no corresponding increase in thorium, so a higher potassium/thorium ratio also results from...
Geology and biology of the sea floor as deduced from simulaneous photographs and samples
K.O. Emery, A.S. Merrill, James V. A. Trumbull
1965, Limnology and Oceanography (10) 1-21
During 1963, 260 paired photographs and large bottom samples were taken on the continental shelf and slope off northeastern United States. The photographs revealed surface characteristics of the sediments and natural attitudes of benthic animals; the samples retrieved specimens for geological and biological examination and identification.Samples are the best source...
Relation of carbon 14 concentrations to saline water contamination of coastal aquifers
B.B. Hanshaw, W. Back, Meyer Rubin, Robert L. Wait
1965, Water Resources Management (1) 109-114
Naturally occurring stable or radioactive isotopes may be used in some places to identify the origin of saline water that contaminates some coastal aquifers. In a recent study to determine the origin of saline water in the Ocala Limestone aquifer near Brunswick, Georgia, the following sources were analyzed for C14 and...
Earthquake magnitudes from hydroseismic data
R.C. Vorhis
1965, Groundwater (3) 12-20
If earthquakes are recorded on your water‐level charts, you can make your own estimate of earthquake magnitudes! As an aid in doing this, this paper presents two graphs: one to calculate distance from well to earthquake epicenter; the other, a nomogram from which to read hydroseismic magnitude plus log C. Examples given show (1) direct computation of...
