Purpose: The primary objective of the eastern oil shale drilling was to obtain cores of the Chattanooga shale, from considerable depths and at long distances from its outcrops. Correlation of the cores with outcrop samples showed the effect of weathering on the shale, as well as changes in the stratigraphy. Of secondary interest was acquisition of information on the stratigraphy of the overlying rocks.

From abstract: Perry and Lewis Counties, east of the Tennessee River, in west-middle Tennessee, are underlain by nearly flat-lying rocks of Paleozoic age, with Mississippian cherty limestones forming the greater part of the surface of the western Highland Rim Plateau ridges. Near the summits of the ridges there is a fairly definite horizon in the chert that contains manganese and iron oxides in varying degrees of concentration. Weathering of the mineralized chert has produced widespread float on the hill slopes and in the beds of small spring branches, and the presence of this float, some of it rich enough for metallurgical manganese ore, has encouraged a search for promising deposits in place. In the present study 52 localities where the mineralized beds crop out or have been prospected were examined.

From abstract: Uranium assays of all the samples collected by the Geological Survey from the Chattanooga shale in east-central Tennessee and southern Kentucky from 1947 to 1949 are assembled here, and conclusions are drawn concerning the distribution of the uranium. The 1108 assays from 80 localities provide reasonably reliable information on the stratigraphic and regional variations of the uranium content.

Preface: This report is an attempt to relate the effects of channel modifications to the resulting instabilities in the fluvial system. The primary objective is to provide the Tennessee Department of Transportation with information concerning channel stability in relation to river crossing structures. Several new analytical techniques are presented that can aid in the understanding of channel adjustment to natural and man-induced stress. The methods of analyses presented herein should be applicable to other areas with alluvial, sand-bed channels, especially in the Gulf Coastal Plains States.

From Preface: "The present account summarizes the results of a long investigation of the rocks of the Great Smoky Mountains (1946-55) by geologists of the staff of the U.S. Geological Survey, in collaboration with those of the Tennessee Division of Geology. The technical details of this investigation have already been set forth at length in professional papers of the U.S. Geological Survey. The present account contains the gist of these findings about the rocks of the mountains, and is accompanied by a map and structure sections in which the surface and underground extent of the rocks are displayed."

The following report describes the findings from an investigation of a uranium-bearing strata undertaken in Hickman and adjacent counties in west-central Tennessee during the summer and fall of 1944. The strata contained radioactive elements within the Chattanooga shale and the Maury glauconitic member of the Ridgetop shale.

The following report covers a diamond drilling project in December 1952 that was started in order to obtain geologic and mining information and samples of uranium-bearing Chattanooga shale in the Youngs Bend area, near Smithville, Tennessee. This report presents uranium content discovered within the mines.

The map presented is preliminary and compiled from unpublished soil association map of Anderson County, and soil map of Rosse(?) County.

This report studies the fluvial-terrace deposits in northwestern Tennessee with the intention of establishing a means of correlating disjunct terrace segments along the Obion River that is independent of terrace height, to document the stratigraphy of selected terrace deposits, and to estimate their numerical ages.

From abstract: This report examines and compares "the quality of water discharging from a strip-mined basin and a relatively unmined basin on the Cumberland Plateau in Tennessee." They determine that "the chemical and aesthetic quality of these waters will directly affect the chemical and aesthetic quality of the water flowing through a proposed national river and recreation area." It includes maps, graphs, and tables.

From abstract: This report presents an evaluation and a list of "potential problems associated with increases in pumpage and urban development" in the Memphis area of Tennessee. These problems include "lowered water levels, contamination of the aquifers, and land subsidence."

From explanation: This map is based on water level measurements made in wells screened in the Eocene Memphis Sand (formerly "500-foot sand"). Monthly low-water levels for the month of August, 1978 from USGS maintained recorder equipped wells and supplemental measurements made on August 22 and 23 of private and industrial wells were used as control. Water levels are commonly at their lowest for the year during late August of early September (Criner and Parks, 1976).

This report evaluates and appraises the lignite reserves found in Lauderdale County, Tennessee. It includes maps and tables.

From introduction: This report summarizes information concerning many aspects of the geology and hydrology at Memphis, Tennessee. It also outlines some of the current problems related to the local geology and hydrology or ones that may arise as a result of urbanization and industrialization of the area.

Abstract: Annual pumpage for both the Memphis Sand ("500-foot" sand) and Fort Pillow Sand ("1400-foot" sand) from the time of initial pumping from these aquifers to 1975 is presented in both tabular and graphic forms . The Memphis Sand supplied 188 million gallons per day in 1975 or 95 percent of the total water used in the area . Pumpage from the Fort Pillow Sand has decreased in recent years and in 1975 was about 4 million gallons per day. Pumping increases from the Memphis Sand have caused an almost continual decline of water levels as shown by graphs , tables, and a series of potentiometric-surface maps. Water-level-change maps show the fluctuations in water levels for two periods of high water use. Water levels in the Fort Pillow Sand are also shown by tables and graphs and a potentiometric-surface map . These graphs illustrate a rise of water levels since 1963, coincidental with pumping reductions. The data presented suggest that a constant pumping rate will cause little water-level decline and that the water levels can be altered for efficient resource management by areally varying the distribution of pumping . The references listed support the information presented in this report .

From introduction: The objective of the present study is to test the feasibility of improving upon the regression equations for estimating streamflow in areas affected by coal mining in the Cumberland Plateau of Tennessee by using land-cover information derived from digital processing of Landsat spectral data. The purpose of this report is to summarize the procedures and significant results of this study.

From abstract: The objectives of this study were to define (1) the average 3-day natural low-flow with a 20-year recurrence interval for five low-flow partial-record sites and one continuous record station, (2) losing and gaining reaches of the main stem of the Sulphur Fork Red River and major tributaries, and (3) the quality of water during low-flow. An additional objective was the collection of continuous streamflow and temperature data at selected sites for development of a thermal model for use as a guide in design and management of a small reservoir.

From introduction: The purpose of this report is to present methods for estimating depths of various recurrence interval floods for unregulated streams in Tennessee. Relations between the size of the drainage basin and flood depths for four hydrologic areas of the state are defined.
