  • Glide and Screw

    Glide and Screw

    Space Groups •The 32 crystallographic point groups, whose operation have at least one point unchanged, are sufficient for the description of finite, macroscopic objects. •However since ideal crystals extend indefinitely in all directions, we must also include translations (the Bravais lattices) in our description of symmetry. Space groups: formed when combining a point symmetry group with a set of lattice translation vectors (the Bravais lattices), i.e. self-consistent set of symmetry operations acting on a Bravais lattice. (Space group lattice types and translations have no meaning in point group symmetry.) Space group numbers for all the crystal structures we have discussed this semester, and then some, are listed in DeGraef and Rohrer books and pdf. document on structures and AFLOW website, e.g. ZnS (zincblende) belongs to SG # 216: F43m) Class21/1 Screw Axes •The combination of point group symmetries and translations also leads to two additional operators known as glide and screw. •The screw operation is a combination of a rotation and a translation parallel to the rotation axis. •As for simple rotations, only diad, triad, tetrad and hexad axes, that are consistent with Bravais lattice translation vectors can be used for a screw operator. •In addition, the translation on each rotation must be a rational fraction of the entire translation. •There is no combination of rotations or translations that can transform the pattern produced by 31 to the pattern of 32 , and 41 to the pattern of 43, etc. •Thus, the screw operation results in handedness Class21/2 or chirality (can’t superimpose image on another, e.g., mirror image) to the pattern.

  • The Håkåneset Rockslide, Tinnsjø

    The Håkåneset Rockslide, Tinnsjø

    The Håkåneset rockslide, Tinnsjø Stability analysis of a potentially rock slope instability. Inger Lise Sollie Geotechnology Submission date: June 2014 Supervisor: Bjørn Nilsen, IGB Norwegian University of Science and Technology Department of Geology and Mineral Resources Engineering I II ABSTRACT The Håkåneset rockslide is located on the west shore of Lake Tinnsjø (191 m.a.s.l), a fjordlake stretching 32 km with a SSE-NNW orientation in Telemark, southern Norway. The instability extends from 550 m.a.s.l. and down to approximately 300 m depth in the lake, making up a surface area of 0.54 km2 under water and 0.50 km2 on land. The rockslide comprises an anisotropic metavolcanic rock that is strongly fractured. Five discontinuity sets are identified with systematic field mapping supported by structural analysis of terrestrial laser scan (TLS) data. These are interpreted as gravitationally reactivated inherited tectonic structures. At the northern end the instability is limited by a steep south-east dipping joint (JF3 (~133/77)) that is one direction of a conjugate strike slip fault set (JF3, JF2 (~358/65)). Towards the south the limit to the stable bedrock is transitional. A back scarp is defined by a north-east dipping J1 (~074/59) surface that is mapped out at 550 m.a.s.l. Kinematic analysis indicates that planar sliding, wedge sliding and toppling are feasible. However, because the joint sets are steeply dipping these failure mechanisms can only occur for small rock volumes and are limited to steep slope sections only. Large scale rock slope deformation can only be justified by assuming deformation along a combination of several anisotropies.

Content writer: Dr.AvishekBhattacharjee, Central National Herbarium, Botanical Survey of India, P.O. – B. Garden, Howrah – 711 103. Module – 15; Content writer: AvishekBhattacharjee Botanical Nomenclature:Concept – A name is a handle by which a mental image is passed. Names are just labels we use to ensure we are understood when we communicate. Nomenclature is a mechanism for unambiguous communication about the elements of taxonomy. Botanical Nomenclature, i.e. naming of plants is that part of plant systematics dealing with application of scientific names to plants according to some set rules. It is related to, but distinct from taxonomy. A botanical name is a unique identifier to which information of a taxon can be attached, thus enabling the movement of data across languages, scientific disciplines, and electronic retrieval systems. A plant’s name permits ready summarization of information content of the taxon in a nested framework. A systemofnamingplantsforscientificcommunicationmustbe international inscope,andmustprovideconsistencyintheapplicationof names.Itmustalsobeacceptedbymost,ifnotall,membersofthe scientific community. These criteria led, almost inevitably, to International Botanical Congresses (IBCs) being the venue at which agreement on a system of scientific nomenclature for plants was sought. The IBCs led to publication of different ‘Codes’ which embodied the rules and regulations of botanical nomenclature and the decisions taken during these Congresses. Advantages ofBotanical Nomenclature: Though a common name may be much easier to remember, there are several good reasons to use botanical names for plant identification. Common names are not unique to a specific plant.

We start with a primitive lattice, having points at rabcuvw uvw, where uvw,, ¢ . So lattice points exist at (0,0,0) and all equivalent positions. If we have a lattice point at xyz,, , then we also have a lattice point at xuyvzw,, . Suppose two lattice points exist at xyz111,, and xyz222,, . If xyz,, is a lattice point, then xyz,, x212121 x , y y , z z is also a lattice point. But this does not imply that for all xyz,, representing lattice points, the values of xyz,, are integers. In particular, it is often useful to represent some of them by half integers. A primitive cell has lattice points at 0,0,0 .

As members of the quartz group, tiger's eye and the related blue-coloured mineral hawk's eye gain their silky, lustrous appearance from the parallel intergrowth of quartz crystals and altered amphibole fibres that have mostly turned into limonite. Tiger iron is an altered rock composed chiefly of tiger's eye, red jasper and black hematite. The undulating, contrasting bands of colour and lustre make for an attractive motif and it is Tigers Eye used for Tigers Eye and ornamentation. Tiger iron is a popular ornamental material Tigers Eye in a variety of applications, from beads to knife hilts. Tiger iron is mined primarily in South Africa and Western Australia. Tiger's eye is composed chiefly of silicon dioxide SiO 2 and is coloured mainly by Tigers Eye oxide. The specific gravity ranges from 2. Serpentine deposits in which are occasionally found chatoyant bands of chrysotile fibres have been found in the US states of Arizona and California. These have been cut and sold as "Arizona tiger-eye" and "California tiger's eye" gemstones. In some parts of the world, the stone is believed to ward off the evil eye. Gems are usually given a cabochon cut to best display their chatoyance.

    1469 The Canadian Mineralogist Vol. 43, pp. 1469-1487 (2005) BORATE MINERALS OF THE PENOBSQUIS AND MILLSTREAM DEPOSITS, SOUTHERN NEW BRUNSWICK, CANADA JOEL D. GRICE§, ROBERT A. GAULT AND JERRY VAN VELTHUIZEN† Research Division, Canadian Museum of Nature, P.O. Box 3443, Station D, Ottawa, Ontario K1P 6P4, Canada ABSTRACT The borate minerals found in two potash deposits, at Penobsquis and Millstream, Kings County, New Brunswick, are described in detail. These deposits are located in the Moncton Subbasin, which forms the eastern portion of the extensive Maritimes Basin. These marine evaporites consist of an early carbonate unit, followed by a sulfate, and fi nally, a salt unit. The borate assemblages occur in specifi c beds of halite and sylvite that were the last units to form in the evaporite sequence. Species identifi ed from drill-core sections include: boracite, brianroulstonite, chambersite, colemanite, congolite, danburite, hilgardite, howlite, hydroboracite, kurgantaite, penobsquisite, pringleite, ruitenbergite, strontioginorite, szaibélyite, trembathite, veatchite, volkovskite and walkerite. In addition, 41 non-borate species have been identifi ed, including magnesite, monohydrocalcite, sellaite, kieserite and fl uorite. The borate assemblages in the two deposits differ, and in each deposit, they vary stratigraphically. At Millstream, boracite is the most common borate in the sylvite + carnallite beds, with hilgardite in the lower halite strata. At Penobsquis, there is an upper unit of hilgardite + volkovskite + trembathite in halite and a lower unit of hydroboracite + volkov- skite + trembathite–congolite in halite–sylvite. At both deposits, values of the ratio of B isotopes [␦11B] range from 21.5 to 37.8‰ [21 analyses] and are consistent with a seawater source, without any need for a more exotic interpretation.
