U.S. DEPARTMENT of the INTERIOR U.S.GEOLOGICAL SURVEY ALK.BIB a Selected Bibliography of Alkaline Igneous Rocks and Related Mine U.S. DEPARTMENT OF THE INTERIOR U.S.GEOLOGICAL SURVEY ALK.BIB A selected bibliography of alkaline igneous rocks and related mineral deposits, with an emphasis on western North America compiled by Felix E. Mutschler, D. Chad Johnson, and Thomas C. Mooney Open-File Report 94-624 1994 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. INTRODUCTION This bibliography contains 3,406 references on alkaline igneous rocks and related mineral deposits compiled in conjunction with ongoing studies of alkaline igneous rocks, metallogeny, and tectonics in western North America. Much of the literature on these topics is not readily recovered by searches of current bibliographies and computerized reference systems. We hope that by making this bibliography available, it will help other workers to access this occasionally hard to find literature. The bibliography is available in two formats: (1) paper hardcopy and (2) Apple Macintosh computer-readable 3.5 inch double density diskette. The computer-readable version of the bibliography is a 725 KB WORD (version 5.0) document. Individual literature citations are arranged alphabetically by author(s) and the order of items in each citation follows the standard U.S. Geological Survey format.

  • The Bearhead Rhyolite, Jemez Volcanic Field, NM
    Journal of Volcanology and Geothermal Research 107 32001) 241±264 www.elsevier.com/locate/jvolgeores Effusive eruptions from a large silicic magma chamber: the Bearhead Rhyolite, Jemez volcanic ®eld, NM Leigh Justet*, Terry L. Spell Department of Geosciences, University of Nevada, Las Vegas, NV, 89154-4010, USA Received 23 February 2000; accepted 6 November 2000 Abstract Large continental silicic magma systems commonly produce voluminous ignimbrites and associated caldera collapse events. Less conspicuous and relatively poorly documented are cases in which silicic magma chambers of similar size to those associated with caldera-forming events produce dominantly effusive eruptions of small-volume rhyolite domes and ¯ows. The Bearhead Rhyolite and associated Peralta Tuff Member in the Jemez volcanic ®eld, New Mexico, represent small-volume eruptions from a large silicic magma system in which no caldera-forming event occurred, and thus may have implications for the genesis and eruption of large volumes of silicic magma and the long-term evolution of continental silicic magma systems. 40Ar/39Ar dating reveals that most units mapped as Bearhead Rhyolite and Peralta Tuff 3the Main Group) were erupted during an ,540 ka interval between 7.06 and 6.52 Ma. These rocks de®ne a chemically coherent group of high-silica rhyolites that can be related by simple fractional crystallization models. Preceding the Main Group, minor amounts of unrelated trachydacite and low silica rhyolite were erupted at ,11±9 and ,8 Ma, respectively, whereas subsequent to the Main Group minor amounts of unrelated rhyolites were erupted at ,6.1 and ,1.5 Ma. The chemical coherency, apparent fractional crystallization-derived geochemical trends, large areal distribution of rhyolite domes 3,200 km2), and presence of a major hydrothermal system support the hypothesis that Main Group magmas were derived from a single, large, shallow magma chamber.

Stirewalt Stephen R. Young Kenneth D. Mahrer Center for Nuclear Waste Regulatory Analyses San Antonio, Texas September 1992 ABSTRACT The long-range goal of the Volcanism Research Project is to assess likelihood of volcanic and magmatic activity in the Yucca Mountain area and the potential for disruption of a repository at Yucca Mountain by that activity. To this end, this report discusses extent of available volcanic and tectonic data for the Basin and Range Physiographic Province, assesses usefulness of these data for constraining conceptual models of tectonism and associated volcanism in the Basin and Range, and addresses use of nonlinear dynamics for analyzing patterns of volcanism. Based on data from review of existing literature, the following conclusions and recommendations are drawn to provide guidance for future work in the remaining tasks of this project: (i) middle to late Cenozoic (i.e., less than 55 million years ago) volcanism in the Basin and Range Province can be broadly correlated

  • Geology and Age of the Lac a La Perdrix Fenite, Southern Gatineau District, Quebec
    CA9700383 -4- Geology and age of the Lac a la Perdrix fenite, southern Gatineau district, Quebec D.D. Hogarth1 and Otto van Breemen2 Hogarth, D.D. and van Breemen, 0., 1996: Geology and age of the Lac a la Perdrix fenite, southern Gatineau district, Quebec; inRadiogenic Age and Isotopic Studies: Report 9; Geological Survey of Canada, Current Research 1995-F, p. 33-41. Abstract: The Lac a la Perdrix fenite lies in the Central Metasedimentary Belt of the Grenville Province. This 30 m wide fenite, adjacent to a narrow calciocarbonatite sill, replaces diopside-oligoclase gneiss and is composed of magnesio-arfvedsonite, aegirine, microcline, albite, and fluorapatite. Near the contact with carbonatite, it contains appreciable monazite and barite whereas aegirine virtually disappears. Fenitization probably took place early in the igneous stage of carbonatite development. A Pb/U monazite age of 1026 ± 2 Ma is thought to date fenite formation. Together with published data, this age shows that carbonatite intruded metamorphic rocks near the close of the Grenville Orogeny. Resume : La fenite de Lac a la Perdrix s'observe dans la ceinture metasedimentaire de la Province de Grenville. Cette fenite, mesurant 30 m de largeur et en position adjacente par rapport a un etroit filon-couche de calciocarbonatite, remplace un gneiss a diopside-oligoclase et se compose de magnesio-arfvedsonite, d'aegirine, de microcline, d'albite et de fluorapatite. Pres du contact avec la carbonatite, la fenite contient de la monazite et de la barytine en quantite appreciable, tandis que l'aegirine disparait pratiquement. La fenitisation a probablement eu lieu au debut de l'episode igne durant lequel s'est form6 la carbonatite.

Agpaitic nepheline syenites have complex, Na-Ca-Zr-Ti minerals as the main hosts for zirconium and titanium, rather than zircon and titanite, which are characteristic for miaskitic rocks. The transition from a miaskitic to an agpaitic crystallization regime in silica-undersaturated magma has traditionally been related to increasing peralkalinity of the magma, but halogen and water contents are also important parameters. The Larvik Plutonic Complex (LPC) in the Permian Oslo Rift, Norway consists of intrusions of hypersolvus monzonite (larvikite), nepheline monzonite (lardalite) and nepheline syenite. Pegmatites ranging in composition from miaskitic syenite with or without nepheline to mildly agpaitic nepheline syenite are the latest products of magmatic differentiation in the complex. The pegmatites can be grouped in (at least) four distinct suites from their magmatic Ti and Zr silicate mineral assemblages.
