  • A Specific Gravity Index for Minerats
    A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951).

  • Vanadium-Bearing Interlava Sediment from The
    VANADIUM-BEARING INTERLAVA SEDIMENT FROM THE CAMPBELL RIVER AREA, BRITISH COLUMBIA BY JOHN LESLIE JAMBOR B.A. University of British Columbia, 1957 THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE In the Department of Geology We accept this thesis as conforming to the required standard THE UNIVERSITY OF BRITISH COLUMBIA April, 1960 In presenting this thesis in partial fulfilment of the requirements for an advanced degree at the University of British Columbia, I agree that the Library shall make it freely available for reference and study. I further agree that permission for extensive copying of this thesis for scholarly purposes may be granted by the Head of my Department or by his representatives. It is understood that copying or publication of this thesis for financial gain shall not be allowed without my written permission-. Department of The University of British Columbia, Vancouver 3, Canada. Date CfMJ X?. ABSTRACT Vanadium is concentrated in laminated, black carbonaceous, siliceous sedimentary rocks at Menzies Bay and Quadra Island, Campbell River area, British Columbia. The vanadiferous rocks are intercalated with amygdaloidal, porphyritic basalts, andesites, and spilites, many of which are pillowform. The writer has correlated the Menzies Bay, Vancouver Island, flows with the Upper Triassic Texada formation volcanic rocks of Quadra Island. A limited petrographic study of the Texada flows in the area has indicated that pumpellyite is copious and widely distributed. Amygdaloidal greenockite is present in trace amounts. The identification of pumpellyite,re• garded as amphibole by earlier writers, marks its first occurrence in British Columbia. In a detailed study of the mineralization assoc• iated with the vanadiferous sedimentary rocks, the first British Columbian occurrences were noted for tenorite, brochantite, and cyanotrichite.

  • IMA–CNMNC Approved Mineral Symbols
    Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Using electron microprobe analysis, X-ray powder diffraction and single-crystal X-ray diffraction with crystal structure determination where possible, it was found that natrobetpakdalite, mendozavilite and melkovite are isostructural with betpakdalite and that obradovicite has a closely related structure. The betpakdalite and obradovicite structure types are based on frameworks containing four-member 3+ clusters of edge-sharing MoO6 octahedra that link by sharing corners with other clusters, with Fe O6 3+ octahedra and with PO4 or AsO4 tetrahedra (T).

BANDV AssrRecr This paper gives the results of a study of the mineralogy of Chuquicamata, euerena, and Alcaparrosa, three sulphate deposits near calama, in Northern chile. The sulphate and chloride minerals, their description, their paragenesis, and the geochemistry of their for- mation, are the primary interest of the paper. The minerals described were collected by the author in 1935. Seventy-six minerals were identified and studied. Eighteen of these minerals are known only from northern chile and twelve are known only from these three deposits. An at- tempt has been made to clear up some of the varietal na:nes and doubtful species that have been described from these mines. Seven new well-defined mineral species were discovered during the research-antofagastite, bandylite, leightonite, ungemachite, and lindgrenite have been described elsewhere; metasideronatrite and parabutlerite are described here. For all of these. complete crystallographic, optical, and chemical data were secured. rm- portant new crystallographic data are presented for the minerals szomolnokite, pickering- ite, rhomboclase, botryogen, lapparentite and natrojarosite. New *+ay data were ob- tained on three minerals and new optical data on sixteen, and nine new chemical analyses are presented. PART I.

  • New Minerals from Lavrion Mining District, Greece
    New Minerals from Lavrion Mining District, Greece Authors: Branko Rieck₁, Uwe Kolitsch₂, Panagiotis Voudouris₃, Gerald Giester₄, Peter Tzeferis₅ (translated from the original “Weitere Naufunde aus Lavrion”, Griechenland, Mineralien Welt, 05/2018) Branko Rieck et al, New Minerals from Lavrion Mining District, Greece, 2018 Already shortly after the finalization of the last comprehensive description of new discoveries from the Lavrion Mining District (KOLITSCH et al. 2014) new finds were made. In parts they could be named in the article mentioned above, most however were made after the publication. It is therefore now time to open a new chapter in the description of this world- famous deposit. In the meantime, new minerals for Lavrion were found especially in polished sections and presented in a short paper for a conference (KOLITSCH et al. 2015). These and many more will be described here. In addition, an uncommon paragenesis of Uranium-bearing minerals was found in the Paleokamariza Mine #18 (SIMON & KAPELLAS 2017, RIECK 2017). And finally, there are four completely new mineral species from Lavrion currently being studied by scientists. Branko Rieck et al, New Minerals from Lavrion Mining District, Greece, 2018 All new discoveries presented here were analyzed by diffraction of X-ray on powders (PXRD) or single crystals (SXRD) and/or by semiquantitative SEM-EDS analysis. Additionally, quantitative Electron Probe and Raman Spectrometry analysis were carried out where it was deemed necessary. Branko Rieck et al, New Minerals from Lavrion Mining District, Greece, 2018 Aeschynite-(Y), (Y,Ln,Ca,Th)(Ti,Nb)2(O,OH)6 At a location discovered by the famous Greek collector Stathis Lazaridis (Lazaridisite) in the Plaka Mine #80 that is well-known for its beautiful anatase crystals in thin “alpinotype” veins also the mineral Aeschynite-(Y) could be identified.

  • MINERAL SPECIES in STOCK -- LIST 2019 This List Is an Alphabetical Listing of All Mineral Species in Stock at the Time of This Printing
    MINERALS UNLIMITED MINERAL SPECIES IN STOCK -- LIST 2019 This list is an alphabetical listing of all mineral species in stock at the time of this printing. Email or write if you need more information about any of the un-priced species. Items with an asterisk * are from the “Type” or original locality. WHAT HAS CHANGED: The 2.5cm (1”) size, as well as most other sizes shown in this list, is generally the size of the matrix, not necessarily the size of the species, with exceptions indicating (micro) with a matrix size given. Sizes with a dash (i.e. 2-3cm) indicates a range of sizes possible, and the best one will be selected from that range. If XL (or xl) is indicated, it may mean a crystal/crystal portion in the size indicated. There may be other size/price options available, ask if I haven’t listed what you want. Some species show more than one price: the higher price indicates another quality or possibly a different locality, not a larger size. Vial is 5/8-dram (about 1/2x1/2-inch area, but a smaller opening.) Where “up” follows a price, other quality specimens are available, please ask for more details. Some mineral groups have been cross-referenced, i.e., TOURMALINE, GARNET, QUARTZ, etc. For example, while the price for almandine will be found under GARNET, you will be directed to the GARNET section if you look up almandine—there you will find “Almandine—see GARNET.” Amphiboles, pyroxenes, micas, feldspars and such are listed only under their mineral names, i.e., ALBITE, BIOTITE, etc.
