项目摘要

This year is the last of the three years project. New techiniques developed in the field of material science have been applied to investigate the formation processes of minerals which are recorded in the macroscopic textures, mineral assembrages, variation of chemical compositons, submicroscopic structures and higher order structures of minerals. The objects of our researches are not only restricted to the materials of the Earth's surface but also the Earth's mantle materials, meteorites and lunar samples. A principle of the material evolutin in the solar system is our goal of this project. In this year's research, we carried out the comprehensive and precise studies on the formation conditions and cooling histories of the earth and planetary materials using the comventional mineralogical methods combined with highly advanced technologies in the modern material science. To promote progresses of their cooperative works, we organized a meeting in Kyoto. In the meeting we discussed on the … More current problems such as ; what kinds of interesting problems we can effectively solve in the field of the earth and planetary science by means of what kinds of methods in the material science. The themes discussed include : 1. distribution of noble gas isotopes in meteorites (by Takaoka), 2. domain structure in kaliophilite and its dependency on the chemical composition (by Kawahara), 3. the chemical composition of Mars ; an estimation from the high pressure experimentsh (by Kamaya, Onuma), 4. application of Gandolfi-camera on the precise determination of the lattice constants (by Nakamuta, Aoki), 5. Local structure of minerals ; application of EXAFS-method on the study of thermal vibration (by Yoshiasa), 6. crystallinity of radiolaria and the geological applications (by Koto), 8. diffusion of elements in olivine under high temperature and high pressure (by Mori), 9. material evolution in the early stages of earth-type planet (by Takeda). Through these presentations we discussed the possibilities how we can effectively develop powerful methods to the various research objects. Less

今年是三年项目的最后一个。在材料科学领域开发的新技术已应用于研究矿物质的形成过程，这些过程记录在宏观纹理，矿物质组装，化学复合材料的变化，亚显微镜结构和矿物质的高阶结构中。我们研究的对象不仅限于地球表面的材料，还限于地球的地幔材料，陨石和月球样品。太阳系中材料的原则是我们的目标。在今年的研究中，我们使用常规矿物学方法与现代材料科学中高级技术相结合的常规矿物学方法进行了有关地球和行星材料的形成条件和冷却历史的全面和精确研究。为了促进其合作工作的进步，我们在京都组织了一次会议。在会议上，我们讨论了……更多当前问题，例如；我们可以通过材料科学中的哪些方法有效地在地球和行星科学领域中有效解决什么样的有趣问题。讨论的主题包括：1。贵族同位素在陨石中（由Takaoka）的分布，2。kaliophilite中的域结构及其对化学成分的依赖性（由Kawahara），3。火星的化学成分；从高压实验（由Kamaya，Onuma）中进行的估计，4。甘道夫 - 相机在晶格常数的精确测定中应用（由Nakamura，Aoki，Aoki），5。矿物质的局部结构； EXAFS方法在热振动研究中的应用（Yoshiasa），6。放射性虫和地质应用的结晶度（由Koto），8。在高温和高压下橄榄石中元素在高温和高压下的扩散（由MORI），9。材料进化的早期阶段（由地球型Planet）（通过Takeda）。通过这些演讲，我们讨论了如何有效地为各种研究对象开发强大的方法的可能性。较少的
