Report discussing earthquake activity in the United States during 1931. The report is broken down by regions and has sections for specific earthquakes.

A report about the fluid inclusions in the upper Mississippi valley zinc-lead district. It discusses the consequences of fluid flow.

Final report analyzing aerial gamma ray and magnetic data in the Baton Rouge quadrangle, including a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

Final report analyzing aerial gamma ray and magnetic data in the Mobile quadrangle, including a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

From introduction: Oil and gas wells and related facilities of the Baxterville field were surveyed to document any physical changes resulting from the Salmon Event. All such structures within a 5-mile radius of Ground Zero were examined and photographed in detail.

Summary: Enid Dam, a unit in the flood-control plan for the Yazoo River, is a rolled-fill structure about 85 ft high and 8400 ft long, and contains about 5-3/4 million cu yd of fill.

This report describes damage to structures by Hurricane Camille in qualitative terms, and with photographs. The investigation was carried out by a team sponsored by the Office of Civil Defense, and it includes conclusions and recommendations.

Summary: "This report provides data on the alluvial aquifer of the Lower Mississippi Valley in the area between Cape Girardeau, Missouri, and Port Gibson, Mississippi. Maps are presented of the Tertiary surface on which the alluvial aquifer rests as well as the geology of this surface and the areas where hydrologic recharge to the alluvial aquifer may occur. A set of piezometric-surface maps, together with hydrographs of observation wells, river stages, precipitation rates, and data on the hydrologic properties of the alluvium, makes it possible to calculate changes which take place in the aquifer. Further data are presented on the chemical quality of groundwater. The relevance of these data to engineering problems is discussed" (p. ix).

Report on model tests related to drainage structures for the Tennessee-Tombigbee Waterway to provide recommendations about construction.

"Approximately 1000 references to published and unpublished items of geologic literature were selected as being pertinent to engineering problems experienced by the Lower Mississippi Valley Division (LMVD) and its districts. Annotations were prepared for about 600 of the references" (p. vii).

Report providing information about experiments performed on core samples taken from the Tatum Salt Dome in Mississippi with an appendix about similar core samples from Louisiana. "All samples were examined petrographically before being subjected to physical tests to develop information on texture, fabric, structure, and composition" (p. vii).

Foreword: This report covers one part of a comprehensive study to determine the relationship between the trafficability of soils and the mobility of military vehicles.

Preface: The study was initiated in early 1951 to develop methods of predicting the moisture content of several soils in the vicinity of Vicksburg, Mississippi.

From abstract: Prototype tests were conducted to comprehensively evaluate the performance of the 84-ft-lift Bay Springs Lock. The evaluation included analysis of the operating characteristics and hydraulic efficiency of the lock as well as a comparison of the physical and analytical model results with the prototype.

From abstract: The Jackson gas field, in Hinds and Rankin Counties, Miss., is in the eastern Gulf Coastal Plain, about 160 miles north of New Orleans and 40 miles, east of the Mississippi River at Vicksburg. The gas is produced from a Cretaceous chalk from 2,088 to 2,236 feet below sea level. Overlying the chalk is the regular sequence of Tertiary rocks found in Mississippi. On the crest of the anticline in the city of Jackson the Cockfield formation of the Claiborne group is exposed, surrounded by the Jackson formation. Some Forest Hill sand of the Vicksburg group is exposed in the northwestern part of the area described. Overlapping these formations are Pliocene and Pleistocene terrace and alluvial deposits, and the entire area is covered by a blanket of less of varying thickness.

From foreword: This report covers one phase of a comprehensive study to determine the relationship between the trafficability of soils and the mobility of military vehicles.

Final report discussing a facility built to test californium-252 in research on moisture, density, and other properties of soil and rock in relation to engineering characteristics.

The following report presents data from the SALMON experiment, an experiment made to study the mechanics of a tamped nuclear detonation in a salt dome in terms of generated shock waves as they are propagated out of the dome and progressively through the crust and mantle of the earth. This experiment was made in the Tatum salt dome, Mississippi, October 22, 1964.

Abstract: "An updated geologic reconnaissance map was prepared of the vicinity of Cypress Creek Dome, Mississippi, at a scale of 1:24,000. Compilaion of previous work, field mapping, and heavy material analyses were used to prepare the map."
