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. -

E-mail: [email protected] (Submitted 08 November 2006; revision accepted 14 May 2007) Abstract–The Lockne and Tvären craters formed about 455 million years ago in an epicontinental sea where seawater and mainly limestones covered a crystalline basement. The target water depth for Tvären (apparent basement crater diameter D = 2 km) was probably not over 150 m, and for Lockne (D = 7.5 km) recent best-fit numerical simulations suggest the target water depth of 500–700 m. Lockne has crystalline ejecta that partly cover an outer crater (14 km diameter) apparent in the target sediments. Tvären is eroded with only the crater infill preserved. We have line-logged cores through the resurge deposits within the craters in order to analyze the resurge flow. The focus was clast lithology, frequencies, and size sorting. We divide the resurge into “resurge proper,” with water and debris shooting into the crater and ultimately rising into a central water plume, “anti-resurge,” with flow outward from the collapsing plume, and “oscillating resurge” (not covered by the line-logging due to methodological reasons), with decreasing flow in diverse directions. -

The Tennessee Meteorite Impact Sites and Changing Perspectives on Impact Cratering
UNIVERSITY OF SOUTHERN QUEENSLAND THE TENNESSEE METEORITE IMPACT SITES AND CHANGING PERSPECTIVES ON IMPACT CRATERING A dissertation submitted by Janaruth Harling Ford B.A. Cum Laude (Vanderbilt University), M. Astron. (University of Western Sydney) For the award of Doctor of Philosophy 2015 ABSTRACT Terrestrial impact structures offer astronomers and geologists opportunities to study the impact cratering process. Tennessee has four structures of interest. Information gained over the last century and a half concerning these sites is scattered throughout astronomical, geological and other specialized scientific journals, books, and literature, some of which are elusive. Gathering and compiling this widely- spread information into one historical document benefits the scientific community in general. The Wells Creek Structure is a proven impact site, and has been referred to as the ‘syntype’ cryptoexplosion structure for the United State. It was the first impact structure in the United States in which shatter cones were identified and was probably the subject of the first detailed geological report on a cryptoexplosive structure in the United States. The Wells Creek Structure displays bilateral symmetry, and three smaller ‘craters’ lie to the north of the main Wells Creek structure along its axis of symmetry. The question remains as to whether or not these structures have a common origin with the Wells Creek structure. The Flynn Creek Structure, another proven impact site, was first mentioned as a site of disturbance in Safford’s 1869 report on the geology of Tennessee. It has been noted as the terrestrial feature that bears the closest resemblance to a typical lunar crater, even though it is the probable result of a shallow marine impact. -

Handbook of Universal Literature
HANDBOOK OF UNIVERSAL LITERATURE ANNE C. LYNCH BOTTA∗ PREFATORY NOTE TO THE REVISED EDITION. Since the first publication of this work in 1860, many new names have appeared in modern literature. Japan, hitherto almost unknown to Europeans, has taken her place among the nations with a literature of her own, and the researches and discoveries of scholars in various parts of the world have thrown much light on the literatures of antiquity. To keep pace with this advance, a new edition of the work has been called for. Prefixed is a very brief summary of an important and exhaustive History of the Alphabet recently published. PREFACE. This work was begun many years ago, as a literary exercise, to meet the personal requirements of the writer, which were such as most persons experience on leaving school and ”completing their education,” as the phrase is. The world of literature lies before them, but where to begin, what course of study to pursue, in order best to comprehend it, are the problems which present themselves to the bewildered questioner, who finds himself in a position not unlike that of a traveler suddenly set down in an unknown country, without guide-book or map. The most natural course under such circumstances would be to begin at the beginning, and take a rapid survey of the entire field of literature, arriving at its details through this general view. But as this could be accomplished only by subjecting each individual to a severe and protracted course of systematic study, the idea was conceived of obviating this necessity to some extent by embodying the results of such a course in the form of the following work, which, after being long laid aside, is now at length completed.
