From introduction: This report deals with ground-water resources of the part of the Branch River basin in northwestern Rhode Island upstream from the U.S. Geological Survey gaging station at Forestdale, Rhode lsland, an area of 79 square miles or 205 square kilometers (figure 1). It is one of a series prepared in cooperation with the Rhode Island Water Resources Board to provide quantitative information on the availability of large supplies of ground water in Rhode Island.

Abstract: Low-flow characteristics of Wisconsin streams at 415 sewage-treatment plants are presented in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow that occurs on the average of once in 2 years and the annual minimum 7-day mean flow that occurs on the average of once in 10 years. The low-flow characteristics at most sewage-treatment plants were determined by correlating baseflow measurements at the sewage-treatment plants to the concurrent daily mean flow at continuous-record gaging stations in the area. The accuracy determined by the standard error of estimate for the 10-year low flow ranged from 18 percent at continuous-record gaging stations to 70 percent when only three base-flow measurements were available. The standard error of 70 percent is larger than anticipated when the project was initiated. This was the result of extremely poor base-flow conditions during the 2-year data collection period. Additional base-flow conditions will be obtained during subsequent years which will improve the standard error somewhere between 29 and 45 percent.

From abstract: This report summarizes the porosity, density, and water content data on about 200 tuff specimens from the Tunnel Beds which compose the lower member of the Oak Spring Formation of Miocene (?) or younger age at the Ul2e tunnel, Rainier Mesa, Nevada Test Site.

A report about thermodynamic properties of several minerals which have been constructed in a form convenient for calculation of chemical equilibria of minerals and of problems related to the heat content of rocks.

The following report covers the effects of the Rainier, Logan, and Blanca explosions on tuff that were determined through observations and measurements on the surface and in drill holes and tunnels.

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.

Report discussing the investigation of possibly commercial amounts of thorium, niobium and rare earths which were found in veins of igneous rock areas in Laughlin Peak, 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.

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.

Abstract: The thermal expansion of NaCl at high pressures and temperatures is estimated by extrapolating high temperature compressibility data to high pressures using finite strain theory. The thermal expansion is apparently negative at pressures over 50,000 bars at 300°C and at higher pressures at other temperatures.

From Introduction: "The primary purpose of this work was to summarize and bring up to date the information on beryl resources as gained from investigations during 1942-45, to examine in detail certain beryl-bearing pegmatites discovered and developed in recent years, and to study other pegmatites and groups of pegmatites known or suspected to contain beryl."

Abstract: "A dioctylphthalate has been isolated from a crude oil by means of adsorption column chromatography. The ester was identified by means of elemental analysis, refractive index, and its infrared adsorption spectrum. Saponification of the isolate and examination of the resultant alcohol by means of infrared adsorption spectra led to the conclusion that the ester is a branched chain dioctylphthalate. This is the first reported occurrence of an ester in crude petroleum."

A report which records the results of experiments dealing with the synthesis of carnotite and its alkali analogues. The work was primarily concerned with the preparation of single crystals suitable for detailed structural analysis, though some insight into the chemistry of the precipitation of carnotite was obtained.
