Mineralogy of Eudialyte Group Minerals From the East Hill Suite Of the Mont Saint-Hilaire Alkaline Plutonic Complex, Including an Alternative Site-Assignment Algorithm & A Proposed Classification System A Thesis Submitted to the Graduate Faculty of the University of New Orleans in partial fulfillment of the requirements for the degree of Master of Science in The Department of Earth and Environmental Sciences by Peter E. Tice B.Sc. McGill University, 1995 May, 2009 Copyright 2009, Peter E. Tice ii ACKNOWLEDGEMENTS This work greatly benefited from the guidance and assistance of a number of people; to them should be conveyed deep gratitude. Dr. Wm. B. Simmons, Jr. is to be thanked first and foremost for his thoughtful commentary on research methodology, analytical procedures, and petrological and mineralogical interpretations. He deserves a great deal of further appreciation for his dedication and patience. Dr. Simmons was gracious and accommodating in allowing the author to choose and direct the subject of his research; he was tolerant of changes in the direction of research, while still providing guidance and leadership; and he was unwavering in his support of the completion of this study. Dr. Simmons and Mr. Alexander U. Falster, as joint operators of the analytical facilities in the Department of Geology and Geophysics at the University of New Orleans, deserve many collective thanks for providing a laboratory at which students are able, instrumentally and financially, to carry out analyses of both a broad scope and a deep extent. This work required a variety of instruments and a number of instrument-hours that would have made its proper development and completion financially unattainable at virtually any other institution. Dr. Matthew W. Totten lent a valuable alternative perspective to this work and gave constant encouragement to the author in all his endeavours. He helped to develop the author’s breadth of expertise by giving the author the opportunity to collaborate on mineralogical projects in the realm of sedimentary petrology. He was an inspiration and role model throughout their relationship at the University of New Orleans. Dr. Karen L. Webber helped to develop the author’s understanding of mineralogical research in a petrological context, assisted the author in preliminary literature searches, gave iii insightful editorial commentary, and served as an example by whom to measure the standards that characterize research of high quality. Dr. Christopher D. Parkinson provided constructive criticism on the organization of this paper. Dr. Robert F. Martin, of McGill University, first inspired the interest of the author in pegmatites, alkaline igneous rocks, and Mont Saint-Hilaire. As advisor for the author’s undergraduate thesis on the mineralogy and crystallization dynamics of a pegmatite dike at Mont Saint-Hilaire, he accompanied the author on several excursions to the locality, provided expert instruction in scientific writing, and participated in numerous discussions on alkaline melts and mineralogy that shaped that thesis and led to this current work. Monsieur J.G. Poudrette of the Poudrette quarry graciously allows limited access to his property for the collection of aesthetic and research specimens. This beneficence is instrumental in the continuing efforts by all researchers to understand Mont Saint-Hilaire and is deeply appreciated. The author’s Mother and Father nurtured the author’s education and interest in the sciences in school and museums and through talks, both formal and informal. They provided the financial means for the author’s undergraduate education and were unconditionally loving and supportive through challenging and trying times. They were always there; they were true parents. The author’s wife, Sherri, was wonderfully understanding of the author’s needs for private, quiet writing time, spending many hours watching their children and looking after the author’s usual chores so that this work could be completed; although, the children did sometimes get to have a look at what daddy was doing—“Look at all the numbers!” In addition to taking iv care of this practical issue, she was unfaltering in her encouragement to bring this research to its written conclusion. Mr. Alexander U. Falster, although a major contributor to this work, is saved until the end to make more conspicuous his inclusion in this section. Through the entire course of his relationship with the author, he has been as a brother, always ready to offer advice, assistance, laughter, or consolation. Mr. Falster operated the electron microprobe for a total of approximately 150 hours to generate the chemical analyses for this work. He, along with Dr. Simmons, instructed the author on the theoretical and practical aspects of operating the electron microprobe, scanning electron microscope, X-ray diffractometer, and direct-coupled plasma spectrometer. Mr. Falster further assisted, when needed, in the author’s operation of the latter three instruments. Also, Mr. Falster is responsible for maintenance, repairs, and upkeep of all of the instruments used by the author at the University of New Orleans. Without his tremendous efforts, a work of this scope would have been impossible. To any family and friends who gave of themselves but who were not mentioned by name, many thanks. This thesis is dedicated to my chemistry teacher from Wyomissing Area High School, Mr. William C. Dowling, who first showed me the magic of chemistry. v TABLE OF CONTENTS LIST OF TABLES ...........................................................................................................................IX LIST OF FIGURES ..........................................................................................................................

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.

The petrographic relations of EGM change with time and advancing crystallization up from Phase II (differentiated complex) to Phase III (eudialyte complex). EGM is anhedral interstitial in all of Phase II which indicates that EGM nucleated late relative to the main rock-forming and liquidus minerals of Phase II. Saturation in remaining bulk melt with components needed for nucleation of EGM was reached after the crystallization about 85 vol. % of the intrusion. Early euhedral and idiomorphic EGM of Phase III crystalized in a large convective volume of melt together with other liquidus minerals and was affected by layering processes and formation of EGM ore. Consequently, a prerequisite for the formation of the ore deposit is saturation of the alkaline bulk magma with EGM. It follows that the potential for EGM ores in Lovozero is restricted to the parts of the complex that hosts cumulus EGM. Phase II with only anhedral and interstitial EGM is not promising for this type of ore.

  • Minerals of the Eudialyte Group from the Sagasen Larvikite Quarry, Porsgrunn, Norway
    = Minerals of the eudialyte group from the Sagasen larvikite quarry, Porsgrunn, Norway Alf Olav Larsen, Arne Asheim and Robert A. Gault Introduction Eudialyte, aNa-rich zirconosilicate with varying amounts of Ca, Fe, Mn, REE, Nb, K, Y, Ti, CI and F, was first described from the llimaussaq alkaline complex, South Greenland by Stromeyer (1819), Since then, the mineral has been described from many other alkaline deposits, and is a characteristic mineral in agpaitic nepheline syenites and their associated pegmatites. In recent years, eudialyte (sensa lata) has been the subject of extensive studies. The broad compositional variations and new insight into the crystal chemistry of the mineral group resulted in the definition of several new species by the Eudialyte Nomenclature Subcommittee under the Commission on New Minerals and Mineral Names of the International Mineralogical Association (Johnsen et al. 2003b). Brown eudialyte (s. I.) is a common constituent of the agpaitic pegmatites in the Langesundsfjord district in the western part of the Larvik plutonic complex (Br0gger 1890). Recent chemical analyses of the mineral have shown that some localities contain ferrokentbrooksite (Johnsen et al. 2003a). Other localities hold eudialyte (sensa stricto). Ferrokentbrooksite is the ferrous-iron-dominant analogue of kentbrooksite with Fe as the predominant element replacing Mn. Kentbrooksite is the Mn-REE-Nb-F end member in a solid solution series between eudialyte (s. s.) and ferrokentbrooksite, with an extension to oneillite (Johnsen et al. 1998, Johnsen et al. 1999, Johnsen et al. 2003a), as well as to carbokentbrooksite and zirsilite-(Ce) (Khomyakov et al. 2003). Carbokentbrooksite has a significant content of carbonate and Na > REE for the N4 site, while zirsilite-(Ce) has REE > Na (with Ce predominant) for the N4 site.

    747 The Canadian Mineralogist Vol. 43, pp. 747-758 (2005) BOBTRAILLITE, (Na,Ca)13Sr11(Zr,Y,Nb)14Si42B6O132(OH)12•12H2O, A NEW MINERAL SPECIES FROM MONT SAINT-HILAIRE, QUEBEC: DESCRIPTION, STRUCTURE DETERMINATION AND RELATIONSHIP TO BENITOITE AND WADEITE ANDREW M. McDONALD§ Department of Earth Sciences, Laurentian University, Sudbury Ontario P3E 2C6, Canada ¶ GEORGE Y. CHAO Ottawa–Carleton Geoscience Centre, Department of Earth Sciences, Carleton University, Ottawa Ontario K1S 5B6, Canada ABSTRACT Bobtraillite is a new, complex zirconosilicate found in igneous breccias and nepheline syenite pegmatites at the Poudrette quarry, Mont Saint-Hilaire, Quebec. It is associated with a burbankite-group mineral, donnayite-(Y), clinoamphibole, albite, aegirine, pyrrhotite, pyrite, annite, analcime, microcline, a white mica (muscovite?), yellow titanite, clinopyroxene and calcite. Crystals are commonly grey to brown in color, blocky to prismatic, elongate along [001], with a maximum length of 2 mm. It is generally found as isolated single crystals or simple parallel intergrowths with two or three members, rarely in small (<0.1 mm) rosettes.
