Report issued by the U.S. Bureau of Mines on the drilling for copper deposits near Pinal County, Arizona in 1949. Topographic and geologic mapping, drilling, and field tests were studied. Tables, maps, and illustrations are presented.

Report issued by the Bureau of Mines over tungsten deposits of Arizona. Characteristics of the tungsten deposits are discussed. This report includes tables, maps, and illustrations.

Wells drilled in the county provide evidence of geothermal energy sufficient for process heat and space heating and cooling applications. Annual energy consumption was estimated for industries whose process heat requirements are less than 105/sup 0/C (221/sup 0/F). This information was then used to model the introduction of geothermal energy into the process heat market. Also, agriculture and agribusiness industries were identified. Many of these are located on or near a geothermal resource and might be able to utilize geothermal energy in their operations.

Abstract: Structure drilling under Contract No. AT(05-l)-120 was begun May 13, 1951, and was suspended June 30, 1951, at Red Rock, Arizona with the completion of 12 holes and 2,390.5 feet of drilling. No mineralization was disclosed in the widely spaced holes. The structure and rock composition was found favorable for a potential drilling area.

Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

This is a report on the copper deposits of Ray and Miami, Arizona.

This report discusses the results of a mineral survey of the Superstition Wilderness and contiguous RARE II Further Planning Areas, Tonto National Forest, Gila, Maricopa, and Pinal Counties, Arizona.

A study was undertaken to explore relationships between wetland characteristics which make them efficient water purifiers versus their ability to serve as wildlife habitat. The effects of designing constructed wetlands for improved habitat on water treatment efficiencies were quantified. Results indicate that some sacrifice in treatment efficiency is required and that the degree of efficiency reduction is dependant upon pollutant loading rates. However, sacrifice in efficiency is much smaller than increase in habitat quality, and can be offset by increasing wetland area. A practical, theoretical application was then attempted.

The National Museum of the Pacific War presents an interview with Alan Tanaguchi. Tanaguchi was a Japanese-American internee at the Gila River Camp in Arizona during World War II. At 19 years old, after the attack on Pearl Harbor, Tanaguchi became a part of the internment program of the War Relocation Authority. He provides detail of life growing up in Stockton, California before December 7, 1941 and after, and experiences of bigotry and racism among his peers. He provides detail of his father being in the Justice Department internment group. He served as the dean of the College of Architecture at the University of Texas at Austin, and at Rice University in Houston. He designed an addition to the Nimitz Museum.

From introduction: "The purpose of this report is to show how mapping of discrete units of the valley fill may lead to a broadened understanding of Cenozoic history of intermontane basins in Arizona. The area described is in the vicinity of Mammoth Arizona where deep dissection has exposed a complex sequence of terrestrial deposits and related rocks."

Map and survey information of the the Aravaipa Valley area in Arizona, including information on well depths, irrigated areas, approximate boundaries, and arbitrary boundaries of ground-water area, as well as general hydrologic data and selected references.

From objectives and scope: Project objectives were to synthesize available geologic information; to determine favorability criteria; and to describe, appraise, and delineate favorable areas of the Dripping Spring Quattzite.
