    Phase equilibria in the hornblende-bearing basic gneisses of the Uvete area, central Kenya (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of metamorphic geology 2 (1984), S. 0 
    Details
    ISSN: 1525-1314
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: Abstract The hornblende-bearing basic gneisses in the Uvete area, central Kenya, were metamorphosed under a narrow range of P and T (6.5 ± 0.5kbar and 530 ± 40°C) of the staurolitekyanite zone in the Mozambique metamorphic belt. They show a wide variety of divariant and trivariant mineral assemblages consisting of hornblende, cumminatonite, gedrite, anthophyllite, chlorite, garnet, epidote, clinopyroxene, plagio-clase and quartz. The bulk and mineral chemistries and the graphical representation of phase relations show that each mineral assemblage approaches chemical equilibrium and defines a unique composition volume in the A′(Al + Fe3+− (13/7)Na)-F(Fe2+)-M′(Mg)-C′(Ca-(3/7)Na) tetrahedron. The composition volumes are distributed quite regularly and do not overlap each other.The phase relations in the Uvete area are in contrast with those in the staurolite-kyanite zone amphibolites in the Mt. Cube quadrangle, Vermont. The amphibolites there contain low-variance mineral assemblages formed under different values of μH2O and μCO2. These assemblages define overlapping composition volumes in the A′-F′-M′-C’tetrahedron.The mineral assemblages in the Uvete area are interpreted as having formed in equilibrium with fluid at a high and nearly constant μH2O value. Such a fluid composition was externally controlled by the supply of H2O-rich fluid expelled from the surrounding pelitic and psammitic rocks. The body size of the basic gneisses in the Uvete area (less than 400m in thickness) was small enough for the fluid to migrate completely.

    Effect of the Ionic Size on Thermal Expansion of Low Cordierite by Molecular Dynamics Simulation (2005)
    Oxford, UK : Blackwell Science Inc
    Journal of the American Ceramic Society 88 (2005), S. 0

    Notes: The effect of ionic size of each cation, Mg, Al, and Si, on the thermal expansion of cordierite, Mg2Al4Si5O18, was systematically investigated by using molecular dynamics simulations. The cell parameter and the thermal expansion are influenced by the ionic size. The ionic size of Al/Si ion has an opposite effect on the thermal expansion along the c-axis to that of Mg ion, i.e., the negative thermal expansion along the c-axis shifts to positive expansion with increasing ionic size of Mg ion and with decreasing ionic size of Al/Si ion.

    Effects of Ionic Size in the Tetrahedral and Octahedral Sites on the Thermal Expansion of Low-Temperature Cordierite (2005)

    Notes: The effects of ionic size in octahedral and two kinds of tetrahedral sites (M, T1, and T2) on the thermal expansion of cordierite were systematically investigated by means of molecular dynamics simulations. Thermal expansion along the a axis could be controlled by varying the ionic size in the M-site, and expansion along the c axis could be controlled by varying the ionic size in the M- and T2-sites. However, the ionic sizes in the M- and T2-sites had opposite effects.

    Monte Carlo simulation of normal grain growth in 2- and 3-dimensions: the lattice-model-independent grain size distribution (1998)
    Springer
    Contributions to mineralogy and petrology 130 (1998), S. 121-133

    Notes: Abstract The phenomenon of normal grain growth in pure single phase systems is modeled with the Monte Carlo technique and a series of simulations are performed in 2- and 3-dimensions. The results are compared with natural and experimental monomineralic rock samples. In these simulations various lattice models with different anisotropic features in grain boundary energy are examined in order to check the universality of the simulation results. The obtained microstructure varies with the artificial parameter T ′ in each lattice model, where T ′ means scaled temperature and controls thermal fluctuation on grain boundary motion. As T ′ (thermal fluctuation) increases, the boundary energy anisotropy characterizing each lattice model becomes less important for the evolution of the microstructure. As a result the difference in the grain size distribution among the lattice models, which is significantly large for low T ′, is reduced with increasing T ′. The distribution independent of both the lattice model and the dimension is obtained at sufficiently high T ′ and is very close to the normal distribution when carrying out the weighting procedure with a weight of the square of each grain radius. A comparison of the planar grain size distribution of the natural and experimental rock samples with the 3-D simulation results reveals that the simulations reproduce very well the distributions observed in the real rock samples. Although various factors such as the presence of secondary minerals and a fluid phase, which are not included in the simulation modeling, are generally considered to influence the real grain growth behavior, the good agreement of the distribution indicates that the overall grain growth behavior in real rocks may still be described by the simplified model used in the present simulations. Thus the grain size distribution obtained from the present simulations is possessed of the universal form characterizing real normal grain growth of which the driving force is essentially grain boundary energy reduction through grain boundary migration.

    Dendritic cordierite in argillaceous hornfels from the Toki area, Gifu Prefecture, central Japan (1990)
    Springer
    Contributions to mineralogy and petrology 104 (1990), S. 390-396

    Notes: Abstract Dendritic cordierite occurs in argillaceous hornfels from the Toki area, Gifu Prefecture, Japan. The cordierite crystal consists of ‘c-arms’ elongated parallel to the c-axes and ‘a-arms’ perpendicular to the c-axis. The latter arms could be divided into six kinds of untwinned ‘a-arms’ with different growth directions elongated parallel to the respective a-axis and twinned ‘a-arms’ elongated parallel to the (110) twin plane. ‘A-arms’ branch out from ‘c-arms’ or other ‘a-arms’ with different growth directions and ‘c-arms’ sometimes branch out from a-arms, leading to a tree-like structure. Each of the ‘c-arms’ contains three kinds of domains related by a three-fold axis about the c-axis. These domains are irregularly distributed without any relation to the shape of the ‘c-arm’ and the domain boundaries are of zigzag shape. This domain arrangement suggests that ‘c-arms’ grew as hexagonal cordierite and were later transformed into orthorhombic cordierite. The fact that each untwinned ‘a-arm’ has a fixed growth direction to its orientation suggests that the ‘a-arms’ grew as an orthorhombic cordierite. From the growth directions of ‘c-’ and ‘a-arms’, orthorhombic and hexagonal phases are considered to grow preferentially along the c- and a-axes, respectively. The branching of a new arm is explained by nucleation on an old arm with a different preferred growth direction. The preferential growth is discussed in terms of a significant chemical potential gradient of the cordierite component. This has been preserved in the mineral zoning observed in the matrix around the cordierite porphyroblast.
