Geophysical and geologic studies in southern Mecklenburg County and vicinity, North Carolina and South Carolina
Frederick A. Wilson
1983, Open-File Report 83-93
Geophysical methods consisting of gravity, aeromagnetics and aeroradioactivity have been applied to part of the Charlotte and Carolina slate belts in southern Mecklenburg County and vicinity to help interpret geology, lithology and structure. High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and...

Short-range vertical variation in organic carbon, carbonate carbon, total sulfur contents and Munsell color values in a core from the Upper Pennsylvanian Stark Shale Member of the Dennis Limestone, Wabaunsee County, Kansas
M.R. Stanton, Joel S. Leventhal, Joseph R. Hatch
1983, Open-File Report 83-315
Organic carbon, total sulfur, carbonate carbon and Munsell color value were determined for 21 successive samples from a 53-cm-thick section of drill core. These samples are from the Stark Shale Member of the Dennis Limestone of Upper Pennsylvanian age, Wabaunsee County, Kansas. The data confirm previous results (Hosterman and Whitlow,...
Sand-wave movement on Little Georges Bank
David C. Twichell
1983, Open-File Report 83-746
A 1-x-1.5-km area on Little Georges Bank (centered at 41?08?N., 68?04?W.) was mapped three times during a ten-month period by sidescan sonar and echo-sounding techniques to assess the morphology and mobility of sand waves on Georges Bank. Sand-wave amplitudes in the survey area ranged from 1-11 m although most were...
Evaluation of water-quality characteristics of part of the Spokane Aquifer, Washington and Idaho, using a solute-transport digital model
J. J. Vaccaro, E.L. Bolke
1983, Open-File Report 82-769
The principal dissolved constituents in water in the Spokane aquifer are calcium and bicarbonate. These constituents (as well as dissolved solids, hardness, and magnesium) each correlate well with specific conductance, whereas chloride, sodium, and nitrate each do not. Specific conductance ranges from 73 to 820 micromhos per centimeter throughout the...

Reconnaissance geology of the Al Ufayriyah quadrangle, sheet 20/42 A, Kingdom of Saudi Arabia
Robert C. Greene
1983, Open-File Report 83-295
The Al Ufayriyah quadrangle is located in the Najd Plateau of southwestern Saudi Arabia between lat 20?30' and 21?00' N.,. long 42?00' and 42?30' E. Two-thirds of the quadrangle is underlain by Precambrian metasedimentary, metavolcanic, plutonic, and hypabyssal intrusive rocks; this area is in part mountainous and in part uneven...

Occurrence and use of ground water in the Venice-Englewood area, Sarasota and Charlotte counties, Florida
Horace Sutcliffe, Thomas H. Thompson
1983, Open-File Report 82-700
In a 75-square-mile area of coastal Sarasota and Charlotte Counties, demand for water is increasing. Groundwater, the principal source of supply, is distributed largely by public water systems. Principal water-bearing formations in descending order, include the surficial aquifer, artesian zone 1 in the Tamiami Formation, zone 2 in the upper...
