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.

Final report documenting a high-sensitivity airborne gamma ray and magnetic survey of the Helena quadrangle including an analysis of the geology and interpretation of geophysical data.

The following report analyzes the aerial gamma ray and magnetic data taken from the Greenwood quadrangle in southeastern Arkansas that was compiled in 1980. This report contains a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

"The objective [of this report] is to produce an inventory of those important ecological along the lower Mississippi River on which siting of major industrial facilities and land clearing operations could have an impact."

This report presents the results of ground water, stream water, and seam sediment reconnaissance in Arkansas, Louisiana, Missippi, Missouri, Oklahoma, and Texas.
