  • The Crystal Structure of Klyuchevskite, K3cu3(Fe,A1)O2(SO4)4, a New Mineral from Kamchatka Volcanic Sublimates
    The crystal structure of klyuchevskite, K3Cu3(Fe,A1)O2(SO4)4, a new mineral from Kamchatka volcanic sublimates M. G. GORSKAYA*, S. K. FILATOV*, I. V. ROZHDESTVENSKAYA'~AND L. P. VERGASOVA~ State University,* LPO 'Burevestnik't St.-Petersburg Institute of Volcanology, Academy of Sciences, Petropavlovsk-Kamchatsky:~, Russia Abstract The crystal structure of klyuchevskite, K3Cu3(Fe3+,A1)O2(SO4)4, was determined in space group 12 using the total of 715 independent reflections up to R 0.12. Klyuchevskite is a structural analogue of piypite (caratiite) K4Cu402(SO4)4MeC1 with the substitution K + + Cu 2+ ~ (Fe3+,A1) + MeC1. Compared to piypite, the ordering of Cu 2+ and Fe 3+ cations in the klyuchevskite structure results in the distortion of the unit cell and in lowering the symmetry of the chains to 1. This brings about a more compact packing of the chains. The chain-like arrangement of the structure determines physical properties of the mineral, its acicular habit, perfect cleavage, strong anisotropy of optical properties and orientation of optical indicatrix. KEYWORDS: klyuchevskite, crystal structure, piypite, Tolbachik volcano, Russia. THE systematic study of the products of fumarolic described (Effenberger, 1985b). The similarity of activity of Tolbachik Main Fracture Eruption (the crystal chemical formulae, and certain physical Kamchatka Peninsula 1975-1976) resulted in the properties of piypite and klyuchevskite (Table 1) discovery of a series of new minerals. One of them and their forms of occurrence indicates that these is klyuchevskite (Vergasova etal., 1989). The minerals are structurally related. The structural mineral fills cavities and small joints in the data obtained for klyuchevskite support this massive sublimates.

    STRONG AND WEAK INTERLAYER INTERACTIONS OF TWO-DIMENSIONAL MATERIALS AND THEIR ASSEMBLIES Tyler William Farnsworth A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemistry. Chapel Hill 2018 Approved by: Scott C. Warren James F. Cahoon Wei You Joanna M. Atkin Matthew K. Brennaman © 2018 Tyler William Farnsworth ALL RIGHTS RESERVED ii ABSTRACT Tyler William Farnsworth: Strong and weak interlayer interactions of two-dimensional materials and their assemblies (Under the direction of Scott C. Warren) The ability to control the properties of a macroscopic material through systematic modification of its component parts is a central theme in materials science. This concept is exemplified by the assembly of quantum dots into 3D solids, but the application of similar design principles to other quantum-confined systems, namely 2D materials, remains largely unexplored. Here I demonstrate that solution-processed 2D semiconductors retain their quantum-confined properties even when assembled into electrically conductive, thick films. Structural investigations show how this behavior is caused by turbostratic disorder and interlayer adsorbates, which weaken interlayer interactions and allow access to a quantum- confined but electronically coupled state. I generalize these findings to use a variety of 2D building blocks to create electrically conductive 3D solids with virtually any band gap. I next introduce a strategy for discovering new 2D materials. Previous efforts to identify novel 2D materials were limited to van der Waals layered materials, but I demonstrate that layered crystals with strong interlayer interactions can be exfoliated into few-layer or monolayer materials.

  • 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.

    Rdosdladq1//1Lhmdq`knesgdLnmsg9Bnmhbg`kbhsd Our featured mineral comes from the most famous mining district in Mexico, first worked for silver ore by the Spanish conquerors more than four hundred years ago. The write-up will examine this mineral with its unique composition and color. OGXRHB@K OQNODQSHDR 2+ Chemistry: CaCu (AsO4)(OH) Calcium Copper Arsenate Hydroxide (or Basic Calcium Copper Arsenate) Class: Phosphates Subclass: Arsenates Group: Adelite Crystal System: Orthorhombic Crystal Habits: Crystals rare, equant to short prismatic; as compact crusts and reniform masses, sometimes radiating; botryoidal coatings; also massive consisting of uniformly indistinguishable crystals Color: Usually grass green, sometimes yellowish green, occasionally bluish green Luster: Vitreous to greasy Transparency: Transparent and subtransparent to translucent Streak: Light green Refractive Index: 1.73-1.84 Cleavage: None Fracture: Uneven; brittle Hardness: 4.5 Specific Gravity: 4.33 Luminescence: None Distinctive Features and Tests: Best field marks are the vivid, grass-green color which is somewhat distinctive among green minerals; relatively high density; lack of fluorescence; and occurrence only in oxidized zones of copper-rich mineralization Dana Classification Number: 41.5.1.2 M @L D The name conichalcite derives from the Greek words konis, meaning “powder,” and chalx, or “lime,” in reference to its common occurrence in powder-like crusts and to its basic, or lime-like, chemical properties. Its correct pronunciation is cone-eh-CAL-site. In the past, conichalcite has also been informally known as “higginsite.” BNL ONRHSHNM 2+ As is evident by its chemical formula CaCu (AsO4)(OH), conichalcite consists of the elements calcium (Ca) and copper (Cu), both with ionic +2 charges, drawn to the combined -3 charge of the arsenate (AsO4) radical and the -1 charge of the hydroxyl (OH) radical.
