The following report covers investigations on sedimentary rocks of Middle Pennsylvanian age in northeastern Oklahoma, southeastern Kansas, and western Missouri. Distribution of uranium and other trace elements in these rocks was studied during 1955 and 1956.

Report discussing the geology of the Rainy Day uranium mine in Garfield County, Utah. From Introduction: "This report describes the relation of the uranium deposit to the local geology and presents several ore and subore analyses which show similarities between this deposit and those in the Shinarump and Moss Back members of the Chinle formation of the Triassic age."

From abstract: The Rainy Day mine in the Circle Cliffs area, Utah, is developed Dn a long slender pod of uranium ore. Ore is localized in siltstone of the Moenkopi formation of Triassic age, on the south edge of a channel about 3,300 feet wide by 40 feet deep that is filled with sandstone of the Shinarump member of the Chinle formation of Triassic age. Shale of the Chinle rests directly on siltstone of the Moenkopi on either side of the channel.

The following report analyzes the contaminant materials found in glaciers and ice caps.

From introduction: The papers comprising the various parts of this report contain the preliminary results of the U. S. Geological Survey investigations in the U12b.02 tunnel at the Nevada Test Site.

The following report describes studies of thermodynamic equilibria of vanadium in aqueous systems as applied to the interpretation of the Colorado Plateau ore deposits.

The following report describes a laboratory sample splitter, the slotted cone splitter, designed in in the form of 60[degree] cone.

The following is a semiannual progress report by the Geological Survey, preliminary in nature, covering the period of June 1 to November 30, 1958, on the subject of radioactive deposits.

From abstract: This report describes the Rainier underground test of September 19, 1957 conducted at the Nevada Test Site with a 1.7 kiloton nuclear device.

From introduction: The information presented in this report is mainly a synthesis of material that has been published on various portions of the northeastern United States underlain by salt deposits.

"This report is a preliminary appraisal of the ground-water conditions in the area southeast of Carlsbad, New Mexico"

The following report is a synopsis of readily available information on the mineralogy, thickness and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas. It's part of a more extensive investigation of salt being carried out by the U.S. Geological Survey in connection with its Investigation of Geologic Processes project on behalf of the Division of Research, U.S. Atomic Energy Commission.

"This report is a synopsis of readily available information on the mineralogy, thickness, and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas."

From abstract: Reconnaissance for radioactive deposits in southeastern Alaska in 1952 was centered in three localities: the northern part of Prince of Wales Island and parts of adjacent islands, the Taku Harbor-Point Astley district, and the Hyder area. Significant concentrations of radioactive minerals were found only in the vicinity of Salmon Bay on the northeastern shore of Prince of Wales Island. In this area radioactive carbonate-hematite veins occur along the coast for about 8 miles. The veins are generally short, irregular, and lenticular, but a few can be traced for more than 300 feet between the low-tide line and the forest cover. The width of the veins normally ranges from less than 1 inch to 2.5 feet; several, however, are 5 to 10 feet wide.

From introduction: A project to use the immense energy concentrated in a nuclear device to construct an experimental deep-water harbor has been proposed by the Atomic Energy Commission and is referred to as Project Chariot; it is one phase of AEC Project Plowshare...During the field conference, Mr. Gerald Johnson of U. C. R. L. requested that the U. S. Geological Survey submit a report on the summer's investigation around the first of November 1958. This preliminary report is in response to Mr. Johnson's request.

A report which refers to a study that indicated there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore.

The following report covers a study of the electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau province where it is indicated that there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore. This report presents the measurements of resistivity trends.

Abstract: "This bibliography supplements the information on salt published in U.S. Geological Survey Bulletin 1019-J, "Annotated Bibliography and Index Map of Salt Deposits in the United States," by Walter B. Lang, 1957. The supplement contains additional information on the salt deposits of the United States and of foreign countries, as well as data on the composition, chemistry, geologic occurrences, geophysical exploration, distribution, technology, and production of salt. Additional supplements will be issued from time to time to keep information on these subjects current."

Preliminary geologic map of the Elk Ridge 3 NE quadrangle, San Juan County, Utah

From abstract: Drilling at the Project GNOME site, which is in the approximate center of sec. 34, T. 23 S., R. 30 E., NMPM, was undertaken in August and September 1958 by the W-W Drilling Company. The purpose of drilling this hole, which is at the precise location of the proposed shaft, was to determine (1) the lithologic and water-bearing characteristics of the rocks of Cenozoic, Mesozoic, and Paleozoic age that lie above the salt-bearing sequence in the Salado formation; (2) the depth to the top of the unleached salt and associated evaporites in the Salado formation; and (3) the local details of the salt-bearing sequence in the Salado formation.
