    The Marl Slate: a model for the precipitation of calcite, dolomite and sulphides in a newly formed anoxic sea (1987)

    Notes: Detailed studies of a new, complete Marl Slate core in South Yorkshire have provided information on isotopic (δ13C, δ18O, δ34S) and geochemical variations (trace elements and C/S ratio) which enable the formulation of a model for carbonate and sulphide precipitation in the Late Permian Zechstein Sea. Calcite and dolomite are intimately associated; the fine lamination, organic character and absence of benthos in the sediments are indicative of anoxic conditions. Lithologically the core can be divided into a lower, predominantly sapropelic Marl Slate (2 m) and an upper Transition Zone (0·65 m) of alternating sapropel and calcite-rich and dolomite-rich carbonates.C/S ratios are 2·22 for the Marl Slate and 1·72 for the Transition Zone respectively, both characteristic of anoxic environments. δ18O in the carbonates shows a large and systematic variation closely mirrored by variations in calcite/dolomite ratio. The results suggest a fractionation factor equivalent to a depletion of 3·8% for 18O and 1·5% for 13C in calcite. The δ34S values of pyrite are isotopically light (mean value = - 32·7%) suggesting a fractionation factor for the Marl Slate of almost 44%, typical of anoxic basins.The results are related to stratification in the early Zechstein Sea. Calcite was precipitated in oxic upper layers above the halocline. Below the oxic/anoxic boundary framboidal pyrite was precipitated, resulting in lower sulphate concentration and elevated Mg/Ca ratio (due to calcite precipitation). As a result of this, dolomite formation occurred below the oxic/anoxic interface, within the anoxic water column and in bottom sediments. Variations in calcite/dolomite ratios, and isotopic variations, are thus explained by fluctuations in the relative level of the oxic/anoxic boundary in the Zechstein Sea.

    A vapour phase preservative treatment of manufactured wood based board materials (1989)

    Notes: Summary The preservative treatment of four different wood based board materials using an esterified borate applied in the vapour phase was investigated. Under optimum conditions complete impregnation via the board faces was achieved in all boards treated. Board moisture content and treatment time had a major influence on retention and depth of penetration of the borate vapour.

    Notes: Kinematic X-ray and electron scattering factors, found with the use of relativistic Hartree–Fock atomic fields, are tabulated for 76 atoms and ions. Parametric fits to these are given in the range of sin θ/λ from 0.0 to 2.0 Å−1. A method is developed to obtain the electron structure factor for forward scattering for a crystal containing ionized atoms.

    Reciprocity in electron diffraction and microscopy (1968)

    Notes: The Reciprocity Theorem of scattering theory is shown to hold generally for electrons scattered elastically in an absorbing medium, and also for inelastically scattered electrons, to a certain approximation. Two scattering symmetry conditions are defined by applying the theorem to crystals having mirror symmetry parallel to the crystal surface, and to centrosymmetric crystals. These are general forms of conditions demonstrated by Fukuhara (J. Phys. Soc. Japan (1966), 21, 2645). A number of symmetry effects observable in electron microscope images of crystals result from one or other of these conditions. The variation of intensity of diffracted beams as a function of angular deviation from the Bragg condition is considered in detail. The symmetry of bright-field images of defects lying at equal distances from the crystal surfaces was first explained by Howie & Whelan (Proc. Roy. Soc. (1961), A 263, 217); such symmetry properties can be conveniently classified and explained by the reciprocity theorem. A method of obtaining high-resolution dark-field images, due to Cowley, is based on the use of the reciprocity theorem. Examples of its application for both Bragg and diffusely scattered electrons are given.

    The effects of n-beam dynamical diffraction on electron diffraction intensities from polycrystalline materials (1969)
    [S.l.] : International Union of Crystallography (IUCr)

    Notes: Calculations based on n-beam dynamical diffraction theory have shown that the intensities of rings and arcs in diffraction patterns from polycrystalline materials are strongly dependent on the experimental conditions. For arc patterns from BiOCl, calculations confirm a revised formula for the intensities from very thin crystals and indicate dependences on the distributions of orientation, thickness and bending of the crystals which are sufficient to account for the wide deviations of recent experimental results from the predictions of the primary extinction formula, based on the two-beam approximation. Inferences regarding the possible errors in electron diffraction analysis of crystal structures, especially for materials containing heavy atoms, are drawn from calculations relating to the intensities of arc patterns from AgTISe2. It is suggested that n-beam calculations should be made in order to avoid serious error in the refinement stages of a structure analysis.
