Summary of Tertiary investigations in western Saudi Arabia, current work by the U.S. Geological Survey and recommended future studies
Donald G. Hadley, Dwight Lyman Schmidt, Robert Griffin Coleman
1983, Open-File Report 83-487
In 1936, geologic work related to the Tertiary System in western Saudi Arabia began with a study of the Umm Gerad barite deposit by K. S. Twitchell. In 1944, a study focusing specifically on Tertiary rocks was conducted by Steineke and others near Jiddah. Small-scale mapping of Tertiary sequences began...
Studies in Tertiary stratigraphy of the California Coast Ranges
Earl E. Brabb, editor(s)
1983, Professional Paper 1213
The correlation of rocks of Paleogene age in California with those in Europe has had a long and complex history that can only be highlighted here. Kleinpell (1938, p. 168-181), in his classic work defining Miocene benthic1 foraminiferal stages of California, attempted to correlate faunas of California with those of...

Altitude and generalized configuration of the top of the Floridan aquifer, St. Johns County, Florida
Rick M. Spechler
1983, Water-Resources Investigations Report 83-4101
The Floridan aquifer is the principal source of freshwater to wells in most of St. Johns County. The aquifer consists of a thick sequence of interbedded limestone and dolomite of Eocene age. The top of the Floridan aquifer, which is irregular throughout St. Johns County, ranges from less than 90...
Preliminary assessment of the geochemistry and mineral favorability of the postorogenic granites of the southeastern Arabian Shield, Kingdom of Saudi Arabia
John S. Stuckless, G. VanTrump, E. H. Christiansen, C. A. Bush, C. M. Bunker, A.J. Bartel
1983, Open-File Report 83-486
Chemical analyses of samples for 19 postorogenic plutons from the southeastern Arabian Shield show that these rocks have average potassium/rubidium ratios (162) and average rubidium/strontium ratios (11.8) characteristic of highly evolved granites. Most of the analyzed samples are peraluminous. Three plutons are physically similar in terms of shape and megascopic...

Regional geohydrology of the northern Louisiana salt-dome basin, part IV, hydraulic characteristics of the Wilcox-Carrizo aquifer
G.N. Ryals
1983, Water-Resources Investigations Report 83-4132
The Wilcox Group of Paleocene-Eocence age and the Carrizo Sand of Eocene age compose the Wilcox-Carrizo aquifer. Results of 25 aquifer tests and permeability determinations from 43 sidewall cores show that the hydraulic characteristics of the aquifer are variable. Studies of the Carrizo showed that hydraulic conductivity increased as sand-bed...

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...

Alteration and vein mineralization, Schwartzwalder uranium deposit, Front Range, Colorado
Alan R. Wallace
1983, Open-File Report 83-417
The Schwartzwalder uranium deposit, in the Front Range west of Denver, Colorado, is the largest vein-type uranium deposit in the United States. The deposit is situated in a steeply dipping fault system that cuts Proterozoic metamorphic rocks. The host rocks represent a submarine volcanic system with associated chert and iron-...

Man-induced channel adjustment in Tennessee streams
C. H. Robbins, Andrew Simon
1983, Water-Resources Investigations Report 82-4098
Channel modifications in Tennessee, particularly in the western part, have led to large-scale instabilities in the channelized rivers and may have contributed to several bridge failures. These modifications, together with land-use practices, led to downcutting, headward erosion, downstream aggradation, accelerated scour, and bank instabilities. Changes in gradient by channel straightening...

Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...

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...
