This report presents the results of a mineral survey of the Emmett Wash Wilderness Study Area, Coconino County, Arizona.

From summary: The Harquahala Mountains BLM Wilderness Study Area is in the Basin and Range physiographic province of west-central Arizona. The present study covers 24,735 acres of the 72,675 acre wilderness study area, preliminary recommended as suitable for inclusion in the National Wilderness Preservation System in La Paz and Maricopa Counties, Arizona. During the winter of 1983-84, under authority of the Federal Land Policy and Management Act (Public Law 94-579), the Bureau mapped and sampled mines and prospects in and near the WSA to determine the mineral resources present.

From summary: In January-April 1984, the Bureau of Mines conducted a mineral survey of the Lower Burro Creek Wilderness Study Area as required by Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976). The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona.

From Abstract: "The Bureau of Mines conducted research to provide technical information needed to devise waste management plans for the processing of manganese nodules.Studies included summary descriptions of Pacific manganese nodules, process options and flowsheets, method for characterizing nodules and their tailings, and results of analyses of laboratory and pilot-plant generated tailings. A summary of the extensive literature review is provided for manganese nodule mineralogy, chemistry, processing techniques, and methods of analyses."

This report provides pertinent geologic information for long-range planning of subsurface coal and gas production from the Hartshorne Coalbeds. Problems encountered include the complex distribution of minable and un-minable coal, high methane content and bed pressure, faulting, variations in degree of dip, presence of natural gas fields in associated sandstones, and legal problems.

From Introduction: "This compilation is the second in a series revising and expanding Bureau of Mines Bulletin 605, "Thermodynamic Properties of 65 Elements-Their Oxides, Halides, Carbides, and Nitrides," by C. E. Wicks and F. E. Block, published in 1963, and including data available through 1959."

Bulletin issued by the U.S. Bureau of Mines containing a compilation of thermodynamic data regarding sulfides. There are tables for standard heat capacities (includes equations), standard entropies, high-temperature relative enthalpies (includes equations), Gibbs energy functions, enthalpies of formation (includes equations), Gibbs energies of formation (includes equations) and logarithms of the equilibrium constants. Documentation in the introduction explains how the tables are organized and use of the data.
