  • Observation of Quadrupole Helix Chirality and Its Domain Structure in Dyfe3(BO3)4
    ARTICLES PUBLISHED ONLINE: 6 APRIL 2014 | DOI: 10.1038/NMAT3942 Observation of quadrupole helix chirality and its domain structure in DyFe3(BO3)4 T. Usui1, Y. Tanaka2, H. Nakajima1, M. Taguchi2, A. Chainani2, M. Oura2, S. Shin2, N. Katayama3, H. Sawa3, Y. Wakabayashi1 and T. Kimura1* Resonant X-ray diraction (RXD) uses X-rays in the vicinity of a specific atomic absorption edge and is a powerful technique for studying symmetry breaking by motifs of various multipole moments, such as electric monopoles (charge), magnetic dipoles (spin) and electric quadrupoles (orbital). Using circularly polarized X-rays, this technique has been developed to verify symmetry breaking eects arising from chirality, the asymmetry of an object upon its mirroring. Chirality plays a crucial role in the emergence of functionalities such as optical rotatory power and multiferroicity. Here we apply spatially resolved RXD to reveal the helix chirality of Dy 4f electric quadrupole orientations and its domain structure in DyFe3(BO3)4, which shows a reversible phase transition into an enantiomorphic space-group pair. The present study provides evidence for a helix chiral motif of quadrupole moments developed in crystallographic helix chirality. t is well known that chirality often plays a critical role in various detect not only crystallographic helix handedness but also the disciplines, such as biology, organic chemistry and particle chirality ascribed to the periodic motif of multipole moments, such Iphysics1,2.

Rossman Division of Geological and Planetary Sciences California Institute of Technology Pasadena, California 91125-2500, U.S.A. grr@ gps.caltech.edu INTRODUCTION Optical spectroscopy is concerned with the measurement of the absorption, reflection and emission of light in the near-ultraviolet (-250 nm) through the mid-infrared ( -3000 nm) portions of the spectrum. The human interface to the geological and mineralogical world is primarily visual. Optical spectroscopy is, in particular, well suited to investigating the origin of color in minerals. The reflection spectroscopy of minerals has been motivated to a large extent by interest in remote sensing. Emission spectra are usually studied in reference to luminescence phenomena. Studies of mineral color, metal ion site occupancy, oxidation states and concentrations have generally been done with absorption spectroscopy. This chapter concentrates on single crystal absorption spectroscopy. Absorption of light by crystals can occur for a number of reasons. For many minerals, the presence of ions of transition elements (e.g., Ti, V, Cr, Mn, Fe, Co, Ni, Cu) in their various oxidation states is the cause of light absorption. In some minerals, the individual ions cause the light absorption while in others it is the interaction between ions such as between Fe2+ and Fe3+ that causes color. In some minerals, rare-earth elements are an important source of color. 2 Some minerals are colored by small molecular units involving metal ions (UOl+, Cr04 -) or anions (S 3- in sodalites). Many sulfide minerals such as cinnabar (HgS) and realgar (As4S4) owe their color to band gaps in the semiconducting sulfides.

  • Cavansite, a Calcium and Vanadium Silicate of Formula Ca(VO)(Si4o1o
    .. ,., Cavansite, a calcium and vanadium silicate of formula Ca(VO)(Si4O1o).4H.P, occurs as sky-blue to greenish-blue radiating prismatic rosettes up to~mm in size associated with its dimorph, pentagonite, in a roadcut near Lake Owyhee State Park in Malheur County, Oregon. Discovery of these two minerals is attributed to Mr. and Mrs. Leslie Perrigo of Fruitland, Idaho, (at this locality in 1961), and to Dr. John Cowles at the Goble locality in 1963 (see below). Associated with the cavansite and pentagonite are abundant colorless analcime, stilbite, chabazite, thomsonite and heulandite, as well as colorless to pale yellow calcite, and rare green or colorless apophyllite. This occurence and a similar emplacement (of cavansite only) near Goble, Columbia County, Oregon (co-type localities), represent the only known deposits of these two minerals in the United States. As determined by X-ray fluorescense and crystal stfiucture analysis, cavansite is orthorhombic, conforms to space group Pcmn (D2h 6), has a unit cell with a=lO.298(4), b=l3.999(7), c=9.6O1(2) Angstroms, contains four formula units, is optically biaxial positive and strongly pleochroic. Pentagonite, the dimorph, occurs as prismatic crystals twinned to form fivelings with a star­ shaped cross section. Also orthorhombic, it belongs to space group 12 Ccm21(C2v ), and has a unit cell with a=lO.298(4), b=13.999(7), and c=B.891(2) Angstroms, and also contains ··four formula units. The pentagonite crystals are optically very similar to cavansite, but are biaxially negative. The cell dimensions given tend to vary· to a small degree, presumably because of varying zeolitic water content.

ABSTRACT Minerals containing cobalt as an essential element display systematic trends in their diversity and distribution. We employ data for 66 approved Co mineral species (as tabulated by the official mineral list of the International Mineralogical Association, http://rruff.info/ima, as of 1 March 2016), represent- ing 3554 mineral species-locality pairs (www.mindat.org and other sources, as of 1 March 2016). We find that cobalt-containing mineral species, for which 20% are known at only one locality and more than half are known from five or fewer localities, conform to a Large Number of Rare Events (LNRE) distribution. Our model predicts that at least 81 Co minerals exist in Earth’s crust today, indicating that at least 15 species have yet to be discovered—a minimum estimate because it assumes that new minerals will be found only using the same methods as in the past. Numerous additional cobalt miner- als likely await discovery using micro-analytical methods.

  • The Metamorphosis of Metamorphic Petrology
    Downloaded from specialpapers.gsapubs.org on May 16, 2016 The Geological Society of America Special Paper 523 The metamorphosis of metamorphic petrology Frank S. Spear Department of Earth and Environmental Sciences, JRSC 1W19, Rensselaer Polytechnic Institute, 110 8th Street, Troy, New York 12180-3590, USA David R.M. Pattison Department of Geoscience, University of Calgary, 2500 University Drive NW, Calgary, Alberta T2N 1N4, Canada John T. Cheney Department of Geology, Amherst College, Amherst, Massachusetts 01002, USA ABSTRACT The past half-century has seen an explosion in the breadth and depth of studies of metamorphic terranes and of the processes that shaped them. These developments have come from a number of different disciplines and have culminated in an unprece- dented understanding of the phase equilibria of natural systems, the mechanisms and rates of metamorphic processes, the relationship between lithospheric tecton- ics and metamorphism, and the evolution of Earth’s crust and lithospheric mantle. Experimental petrologists have experienced a golden age of systematic investigations of metamorphic mineral stabilities and reactions. This work has provided the basis for the quantifi cation of the pressure-temperature (P-T) conditions associated with various metamorphic facies and eventually led to the development of internally con- sistent databases of thermodynamic data on nearly all important crustal minerals. In parallel, the development of the thermodynamic theory of multicomponent, multi- phase complex systems underpinned development of the major methods of quantita- tive phase equilibrium analysis and P-T estimation used today: geothermobarometry, petrogenetic grids, and, most recently, isochemical phase diagrams. New analytical capabilities, in particular, the development of the electron micro- probe, played an enabling role by providing the means of analyzing small volumes of materials in different textural settings in intact rock samples.

They are thermally metamorphosed due to the Cretaceous Hirao granodiorite intrusion. As a result, neither the fossil record nor the record of the regional (Sangun) metamorphism has been preserved. We investigated the geologic relationships among these units. The tectonic collage model associated with ac- cretionary processes proposed by Kanmera and Nishi (1983) seems the most reasonable. The Hirao Limestone and the uppermost part of the Tagawa metamorphic rocks may be a large olistolith formed during the accretion of the Palaeozoic formation. Petrological studies show that the area was thermally metamorphosed as revealed by widespread occur- rences of biotite in pelitic rocks both in the Tagawa metamorphic rocks and in the Kagumeyoshi Formation. Garnet occurrences in the pelitic schists close to the Hirao granodiorite suggest about 700°C for the peak meta- morphic temperature of contact metamorphism, based on garnet－biotite geothermometers.
