From preface: This bulletin is based upon the observations of the Tertiary and Cretaceous strata exposed along the Tuscaloosa, Tombigbee, and Alabama Rivers in the state of Alabama.

Preface: The author of this paper gives a thorough description of a complex of very unusual igneous rocks and associated hydrothermal deposits.

From purpose and scope: The purpose of this study are to derive base flow estimates for representative parts of the Cretaceous and Tertiary clastic outcrop area as an aid in estimating recharge to the sand aquifers; to use base flow relations to estimate aquifer hydraulic parameters; and to relate the lithology of the aquifer to the streamflow duration curves.

Purpose and scope: The purpose of this report is to assemble and present hydrologic and geologic data collected by the U.S. Geological Survey during the drilling and testing of the test well. Hydrogeologic data collected are presented in tables, graphs, and diagrams. These data include lithologic, geophysical, and sample logs, and the results of aquifer tests and chemical analyses of ground water.

From introduction: The objective of this project is to measure the impact coal mining has on the hydrologic system and to develop the capability for predicting the effect of future mining on water resources. To achieve this necessities isolating the problems and measuring the parameters involved before, during, and after mining.

Abstract: Hydrologic data are being collected in four basins in the Warrior coal field to provide baseline information to aid in determining the effect mining will have on water resource Basins monitored are in two different geologic and hydrologic environments. Well yields from the Pottsville Formation generally range from 0 to 0.3 L/s, whereas well yields from the Coker Formation generally range from 0.3 L/s to 6.4 L/s. Streamflow distribute reflects seasonal precipitation. Streams draining basins underlain chiefly by the Pottsville Formation frequently go dry, whereas those draining basins underlain chiefly by the Coker Formation have well sustained low flows. Water in the Pottsville Formation is slightly acidic and moderately hard to very hard. Dissolved solids concentrations ranged from 176 to 268 mg/L. Water in the Coker Formation is soft, far less mineralized and more acidic than water in the Pottsville. Surface water is generally soft, acidic, and low in dissolved solids concentrations. Water in streams draining basins underlain chiefly by the Pottsville Formation was slightly more mineralized and less acidic than water in streams draining the Coker Formation.

From abstract: "In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field work was done to determine the distribution, thickness, and structural setting of the shale." The report contains information regarding location and drainage, geology, the drilling program, subdivisions of the Sequatchie anticline, and unpublished reports.

From abstract: "Sediments of the inner part of the southern Atlantic Coastal Plain have been sampled and examined for monazite." The report provides sections on general geology, field and laboratory methods, distribution of monazite, and other mineral products.

"A detailed estimate of the reserves of coal in Alabama and a description of the stratigraphy of the coal-bearing rocks."

The following report summarizes the locations, resources, and petrophysical data of known bitumen-bearing deposits located primarily in Alabama, California, Kentucky, Texas, and Utah.

"The results of an investigation of the Chattanooga shale along the Sequatchie anticline of Tennessee and Alabama are summarized in this report. The project was of an exploratory nature designed to 1) obtain fresh core samples from areas where analyses of outcrop samples showed uranium contents as high or higher than those of the Youngs Bend area in DeKalb County, Tenn.; 2) learn more about the distribution and thickness of the shale in those areas and, if necessary, do some geologic mapping; 3) observe general topographic, drainage, and geologic conditions that would affect the mining of shale."
