Regional Geophysical Investigations of the Uravan Area, Colorado

Description: From introduction: Geophysical surveys have been made in the Uravan area, in southwest Colorado, with the aim of providing information on regional geology, especially on those aspects that may not be apparent from surface evidence alone. Aeromagnetic surveys were made in 1952, and regional gravity surveys were made during the summers of 1953 and 1954. Figure 1 shows the area covered. Information on surface geology was obtained from publications, from geologists working on the Colorado Plateau, and from personal observations.

Mineral Resources of the Honeycomb Buttes Wilderness Study Area, Fremont and Sweetwater Counties, Wyoming

Description: From summary: This report includes field investigations to evaluate the mineral resource potential of the Honeycomb Buttes were conducted during the summer of 1984. Geologic mapping, geochemical sampling, geophysical surveys, stratigraphic and sedimentological studies, and surveys of prospects delineated areas of very low grade placer gold deposits in terrace gravels and low and moderate resource potential for additional similar undiscovered placer gold deposits, low and moderate resource potential for small uranium deposits, moderate resource potential for accumulation of oil and gas, and low resource potential for coal and oil shale.

Mineral Resources of the Sand Dunes Wilderness Study Area, Sweetwater County, Wyoming

Description: From summary: In this report the area studied is referred to as the "wilderness study area" or the "study area". Investigations of mineral occurrences in and near the wilderness study area during 1984 and 1985 indicated high mineral resource potential for undiscovered deposits of coal, moderate potential of oil shale and natural gas, low potential for oil, and identified resources of claystone, shale, and sand.

Evaluation of a Proposed Connector Well, Northeastern DeSoto County, Florida

Description: Abstract: At a 24,000-acre citrus grove, a connector well is proposed as a resource management tool for capturing water normally lost through evapotranspiration and by excess runoff. Such a well would connect the surficial sand aquifer with the deep, highly transmissive limestone Floridan Aquifer. Because of natural head differences, water would move by gravity flow from the sand into the Floridan Aquifer, thus replenishing water withdrawn for irrigation from the Floridan Aquifer. A 70-acre marsh was selected as the test site based on analyses of hydraulic conductivity, porosity, and water quality. Recharge rate through the connector well under steady-state conditions is estimated at 160 gallons per minute. The proposed connector well is designed to have 10-inch screens opposite zones in the 45-foot thick sand aquifer, be cased for 400 feet opposite confining beds and a secondary limestone aquifer, and be open hole for about 250 feet in the Floridan Aquifer. A graded-sand filter pack placed around the screened sections of the well will increase its efficiency.

Simulations of Non-Steady Flow in a Glacial Outwash Aquifer, Southern Franklin County, Ohio

Description: From introduction: This report is part of an overall study to model the flow and to describe the water-quality characteristics of the glacial outwash aquifer in part of the Scioto River basin. The purpose of this report is to describe the development of a transient-state digital-computer model and the simulated water-level resulting from anticipated withdrawal by up to six new municipal wells.

Geology of the Mount Katmai Area, Alaska

Description: From abstract: The Mount Katmai area is on the Alaska Peninsula and comprises the Mount Katmai quadrangle, the Cape Douglas area of the adjoining Afognak quadrangle, and parts of the Karluk and Naknek quadrangles. The area, which includes nearly all the Katmai National Monument, is one of high relief and is drained by streams of preglacial origin. At least two ice advances are indicated by the moraine configuration. Present-day glaciation is restricted to numerous alpine glaciers in the mountain areas. Fifteen recently active volcanoes roughly form a line from Mount Douglas to Martin Mountain.

Water-Quality Assessment of White River Lake Between Lake Sequoyah and Beaver Reservoir, Washington County, Arkansas

Description: From abstract: A study was made of the White River between Lake Sequoyah and Beaver Lake to determine the quality of the river under existing conditions and how the effluent from the Fayetteville municipal wastewater-treatment plant, the only point source discharger of waste effluent to the river, affects this quality.

Use of the STORM Model for Estimating the Quantity and Quality of Runoff from the Metropolitan Area of Houston, Texas

Description: From introduction: The purpose of this study, made in cooperation with the Texas Department of Water Resources, was to adapt an existing model to utilize available streamflow and water quality data to compute runoff from the Houston area and to compute the concentrations and loads of selected water-quality constituents contained in the inflow to Galveston Bay.

Optical Calcite Deposits of the Republic of Mexico

Description: From abstract: Many small deposits of optical calcite (Iceland spar) were discovered in the States of Chihuahua, Durango, Sonora, and Sinaloa from early in 1942 to late in 1944. Exploration that began in Sonora led to the discovery of commercial deposits in the eastern part of that State, and subsequently other deposits were found and mined in southwestern and northeastern Chihuahua and in western and central Durango. The largest deposits can be reached by foot or by horse in from 1 to 3 hours from the nearest truck roads, but some of the small deposits are 1 to 3 days by horse from the nearest roads.

Man-Induced Channel Adjustment in Tennessee Streams

Description: Preface: This report is an attempt to relate the effects of channel modifications to the resulting instabilities in the fluvial system. The primary objective is to provide the Tennessee Department of Transportation with information concerning channel stability in relation to river crossing structures. Several new analytical techniques are presented that can aid in the understanding of channel adjustment to natural and man-induced stress. The methods of analyses presented herein should be applicable to other areas with alluvial, sand-bed channels, especially in the Gulf Coastal Plains States.

Trace Elements Reconnaissance of the Southern Highway Belt, South-Central Alaska

Description: Abstract: A radiometric reconnaissance of the areas adjacent to the principal highways and secondary roads of south-central Alaska was carried out during the summer of 1947. The investigation included the examination of nine gold-placer workings, five gold lodes, a gypsum mine, and a copper prospect. Nearly all of the lithologic types outcropping in the highway belt were tested. No significant amounts of radioactive material were found.

The Spectrophotometric Determination of Uranium by Means of the Azide Ion

Description: Abstract: A method has been devised for the spectrophotometric determination of uranium by means of the azide ion. The method possesses several advantages over the various thiocyanate procedures. It has a slightly higher sensitivity, an aqueous medium is used, and the reaction product is more stable. Within the concentration limits tested, Beer's law is obeyed.
