The purpose of the AZGS - to assist the wise use of lands and mineral resources in Arizona by providing scientific and IN ARIZONA investigative research and information - was essentially unchanged. The ancestral AZGS began in 1881, when the Office of the Terri­ torial Geologist was established by the Territorial Legislature. The Arizona Bureau of Mines* primary duties were to collect and provide information about mineral resources. In 1893 the University of Arizona established a testing lab­ oratory, known informally as the "Bureau of Mines." From then until Bulletin 168 statehood in 1912, Territorial Geologists were also affiliated with the 1961 "Bureau of Mines" and the university. A 1915 statute formally estab­ lished the Arizona Bureau of Mines as a State agency administered by (reprinted 1981 and 1988) the University of Arizona, continuing, essentially unchanged, the func­ tions of the "Bureau of Mines" and. the Territorial Geologist. Data collection and research activities continued to be· concentrated on mineral resources. Sixty-two years later, in 1977, the Bureau's enabling legislation was modernized and its name was changed to the Arizona Bureau of Geology and Mineral Technology. It continued to be admin­ istered as a diVision of the University of Arizona. The Bureau was charged with investigating geologic hazards and limitations, as well as the geologic framework and mineral resources of Arizona, in anticipil­ tion of population growth and increased competition for and conflict over land, mineral resources, and water. The AZGS publishes maps, books, and reports, which are available for inspection at the AZGS office in Tucson and may be purchased through the mail. The AZGS office includes a library that is open to the public during normal working hours. Arizona Geology, published quarterly by the AZGS, contains summaries of AZGS research, announcements of new publications and theses, and short, general­ interest articles on the geology of Arizona.

  • GEOLOGY and L\1IN"ERAL RESOURCES of ARIZONA

    GEOLOGY AND l\1IN"ERAL RESOURCES OF ARIZONA Arizona Bureau of Mines * . Bulletin 180 (Part I) 1969 (reprinted 1989 and 1991) *currently the Arizona Geological Survey MINERAL AND WATER RESOURCES OF ARIZONA PART I GEOLOGY AND MINERAL RESOURCES PREPARED BY THE UNITED STATES GEOLOGICAL SURVEY AND THE ARIZONA BUREAU OF MINES 36 GEOLOGY AND TOPOGRAPHY (By Philip T. Hayes, U.S. Geological Survey, Denver, Colo.) 3.· INTRODUCTION In order to describe the occurrence and extent of Arizona's mineral and water resources, some knowledge of the geology of the region is fundamental. The character and structure of the rocks near the earth's surface not only control the kinds of resources that may be found, but exert a strong control on the topography which in turn affects the climate, the accessibility, and the probable extent of human activities. The following general outline of Arizona's geology and topography with a brief resume of economic mineral resources IS intended to pro­ vide this background. More detailed resumes of the geology of the State were written by Darton (llJ25) and 'Wilson (1962), and popularized accounts were given by Cross and others (llJ60 ) and Cooley (1961) . Review articles on diverse aspects of the geology of sizable parts of the State are present in guidebooks edited by Shride (1952), Thume (1952), Cooper (1955), Anderson and Harshbarger (1958), Heindl (1959), Weber and Peirce (1%2), Trauger (1961), and Titley (1968). An indexed bibliography (Moore and Wilson, 1965) lists most papers published on the geology and mineral resources of Arizona through 1964, and will aid the reader wishing further details on specific subjects.

Depending on where the gold is found, this may be done by panning or through dry blowing. Each of these methods relies on the property of density. As gold has a very high density compared to the rock, soil and sediments it is contained in, it can be separated out by exploiting this property as it will fall to the bottom of mixtures that are allowed to settle out. The process of panning is used when small pieces of gold are found in creeks and rivers. It involves using a large shallow dish (pan) to scoop out some of the sediments in the riverbed and a small amount of water. You use a swirling motion with the pan tipped away from you and allow small amounts of the sediments and water to spill over the edge of the pan. When you have only a small amount of the sediments remaining in the pan, you will be able to see any gold particles that remain at the bottom of the pan. During the West Australian gold rush, most of the gold was being found in dry areas and water was a scarce commodity.

Plans are published by the U.S. Fish and Wildlife Service, and are sometimes prepared with the assistance of recovery teams, contractors, state agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director, or Director, as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery tasks.

    Tumacacori Potential Wilderness Area Evaluation [PW-05-03-D2-001]

    Tumacacori Potential Wilderness Evaluation Report Tumacacori Potential Wilderness Area Evaluation [PW-05-03-D2-001] Area Overview Size and Location: The Tumacacori Potential Wilderness Area (PWA) encompasses 37,330 acres. This area is located in the Tumacacori and Atacosa Mountains, which are part of the Nogales Ranger District of the Coronado National Forest in southeastern Arizona (see Map 4 at the end of this document). The Tumacacori PWA is overlapped by 30,305 acres of the Tumacacori Inventoried Roadless Area, comprising 81 percent of the PWA. Vicinity, Surroundings and Access: The Tumacacori Potential Wilderness Area is approximately 50 miles southeast of Tucson, Arizona. The Tumacacori PWA is centrally located within the mountain range and encompasses an area from Sardina and Tumacacori Peaks at the northern end to Ruby Road at the southern end and from the El Paso Natural Gas Line on the eastern side to Arivaca Lake on its western side. The PWA is adjacent to the Pajarita Wilderness Area, Arivaca Lake and Peña Blanca Lake. Both Pena Blanca and Arivaca Lakes are managed by the Arizona Game and Fish Department. Interstate 19 (I-19) connects the Tucson metropolitan area to the City of Nogales and the incorporated community of Sahuarita. The unincorporated communities of Green Valley, Arivaca Junction-Amado, Tubac, Tumacacori-Carmen and Rio Rico, Arizona and Sonora, Mexico are within close proximity to the eastern side of the Tumacacori Mountains and the PWA. State Highway 289 provides access from I-19 across private and National Forest System lands into the Tumacacori Ecosystem Management Area to Peña Blanca Lake and Ruby Road (NFS Road 39).

Bunr Department of Geology Arizona State University Tempe, Arizona 85281 Abstract The crystallization sequence and metasomatic alteration of spodumene (LiAlSizOe), montebrasite(LiAIPO4(OH,F)), and lithiophilite (Li(Mn,Fe)PO+)are describedfor nine zoned lithium pegmatitesin the White Picacho district, Arizona. The observedcrystalliza- tion trends suggesta progressiveincrease in the activities of lithium species(spodumene follows microcline as the principal alkali aluminosilicate), as well as an increase in the activities of the acidic volatiles phosphorus and fluorine (montebrasite succeedsspodu- mene as the stableprimary lithium phase).Much of the lithiophilite occurs with columbite, apatite, beryl, zircon, and tourmaline in cleavelanditecomplexes that formed in part at the expenseof quartz-spodumenepegmatite. Fracture-controlledpseudomorphic alteration of the primary lithium minerals is widespread and apparently is the result of subsolidus reactionswith residualpegmatitic fluids. Spodumenehas been replacedby eucryptite, albite, and micas. Alteration products of montebrasite include low-fluorine secondary montebrasite,crandallite (tentative), hydroxylapatite, muscovite, brazilianite, augelite (tentative),scorzalite, kulanite, wyllieite, and carbonate-apatite.Secondary phases identi- fied in altered lithiophilite include hureaulite, triploidite, eosphorite,
