Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.

"The Purpose of this paper is to present a preliminary discussion of the stratigraphy of the park city and phosphoric formations with special emphasis on the phosphatic parts and to discuss the distribution of phosphate in Utah. The Mississippian deposits are discussed only briefly because of the lack of new data concerning them"

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 purpose and scope: This report describes geohydrologic conditions in the Mississippi salt-dome basin in the area of the Cypress Creek and Richton salt domes. It incorporates data from the area characterization investigations in Mississippi and provides a foundation of technical information for subsequent, more detailed hydrologic investigations.
