The Synthesis of Opalin Materials Takajiro Shimohira, Tsutomu Hiroshima: National Institute for Researches in Inorganic Materials, Sakura-mura, Niiharigun, Ibaraki Opalin materials which show some of the characteristics of natural precious opal have been synthesized. The process of making the materials was as follows;1) Monodispersed suspensions of spherical silica particles of colloidal size were produced by means of hydrolysis of ethyl silicate.2) An ordered close-packed array of hydrated silica particles has been achieved by sedimentation over a period of several months.3) Sintering and impregnation method were used to harden the arrays of stacked spheres.

自然科学成立の根拠やその方法・分類などを批判哲学の立場から論じることは,カント以来多くの哲学者や科学者によって試みられているが,それらの中で鉱物学の地位というものは,かならずしも充分に論じ尽くされてはいないようである。鉱物学の過去における役割りはともかくとして,少くとも現在の鉱物学は,一つの境界領域科学として位置づけられる― と著者は考える。そして,鉱物学がどのような境界領域を占めているかを明らかにするためには,まずいわゆる地学の位置づけを論じなければならない。

Geologic minerals have their own characteristic features in the ultraviolet (UV), visible (Vis), and near infrared (NIR) wavelength regions (e.g., 0.3 to 2.6 μm) of their reflectance spectra. Therefore, meteorites and rocks, which are mixtures of many different minerals, show various, complex, overlapping features in their spectra. Reflectance spectra of asteroids indicate varying surface mineral compositions, some of which are similar to but others are different from meteorites. By classifying asteroids based on their reflectance spectra, their surface materials are shown to vary from high to low temperature materials as they go farther from the Sun. This may imply both that planetesimals in the early solar system had such zoned distribution by (electromagnetic) heating from the Sun or that the inner asteroids grew rapidly enough to make use of short-life radioactive nuclides such as 26Al as a heat source. If we look into the details, however, there are many unresolved questions as to the relationship between asteroids and meteorites such as the issues on the S asteroids and ordinary chondrites.

The characteristic feature of mineral structures strongly depends not only on the space symmetry, but also on the bonding relation of them. The implication of graph theoretical approach for understanding the mineral structures on the above view point is discussed with special refence to three dimensioanl frameworks of tectosilicates.

Rheology of the Earth's crust and mantle is simulated by the plastic behaviour of the polycrystalline quartz and plagioclase, olivine, spinel and perovskite, respectively. To infer the dynamics of the Earth's interior reaching the core-mantle boundary, it needs to study the constitutive flow laws and preferred lattice orientation formation of these crustal and mantle materials. The aim of this paper is to review the recent development of the rheological study of these processes and to add the new constraints on the seismically anisotropic convective mantle.

This is to review some phases in the history of petrography and petrology. Petrology has developed on a deep understanding that a rock is not a rock-fragment in any sample case but an important constituent of the earth and planets. Some recent works on some rock-forming minerals done in my laboratory are introduced in this paper. Some random thoughts on amalgamators of mineralogy and petrology are presented. Mineralogy has developed recently as mineralogical science. It has two main aspects: (a) earth and planetary science, and (b) material science. Mineralogical science as material science should consider the earth and planets to develop further.

Until the middle of the seventeenth century, studies on crystal have been made in mineralogy. At the end of the eighteenth, the classical crystallography as one part of mineralogy has been taken up into the academic system. On and after the nineteenth century, the crystallography has formed the own originl system, andhas developed in an intimate mutual relation with physics and chemistry as basicsciences. In the middle of the nineteenth century, the cristallography has developed as amodern science, and was differentiated into structural crystallography or mathematical crystallography, physical crystallography or crystal physics, and chemical crystallography or crystal chemistry. In these mutual relations, the synthesis of the branches has assumed the character of crystal sciences, and was permited in physics, chemistry and material science as a basic science and also in metallurgy, material technology, pharmancy and agricalture as applied sciences. The crystal science has developed as an interdisciplinary science and has grown into an intimate relation with other sciences. In this paper, we sum up the aspect of the progress by describing the epoch-making events and historical consideration of modern crystallography, concerned with other sciences, during the early nineteenth century up to the first half of the twenteenth century. Besides, we try to show the results of research summing them up in a chronological table as an additional remark.

Comprehension of metastable states in the course of phase transition, decomposition, melting, crystallization is one of significant subjects in the solid state earth dynamics. The following categories in the electronic, atomic or lattice transformation must be taken into account for the metastable phenomena of the above structure changes; (A) kinetic factor such as nucleation rate, growth rate, rate of compression and depression, heating rate and reaction duration, (B) environmental physical and thermodynamical parameters. In addition to experimental approaches to clarify metastable states, atomistic computer simulations offer informations of the precursor phenomena of structure changes under the desired physical conditions. For an example of these calculations, present MD calculation simulates the mechanism of pressure-induced amorphization of GeO2 and its polymorphic phase transformation of post-rutile phase under hydrostatic and nonhydrostatic conditions.

It is worthwhile to note that hydrogen atoms sructually bound to minerals can interact with network-forming oxygen atoms in minerals through hydrogen-bonding. This suggests the significance of chemical state of hydrogen on studying the role of hydrogen to the change in physicochemical and elastic properties of materials in the mantle. IR spectroscopy provides us with much information on the chemical states of OH species contained in these H-carrying minerals. This paper reviews the advantages of IR spectroscopy to the speciation of OH in minerals, quantitative analysis of hydrogen and determination of direction of OH dipole moment in a single crystal along with the several attentions to be paid on thepractical experimantal procedures. Furthermore, speciation of OH in the olivine-wadsleyite-ringwoodite system and its potential role on mantle dynamics is mentioned in detail. It is a definite fact that IR spectroscopy is one of the most promising method to study properties of hydrogen in minerals, but a complementarity use of other methods such as neutron diffraction will be necessary for thorough understanding of hydrogen in minerals.
