1. Tagiri calculated the relationship between the strength of wavy extinction of quartz and the rotation angle of quartz-lattice in mylonites. Then, Tagiri researched the relationship between the deformation degree and the infiltration speed of fluid in mylonites.2. We found the silicate gel in Miocene subaqueous lava flow. The gel has oxidized very quickly at speed per second. It concluded that fluid and oxygen diffusion was almost zero during 15My in this sample.3. Tagiri and Fujinawa studied the petrochemical transformation of migmatites, and described the melt-separation from restitic material in migmatites.4.We observed the crystal growth of tourmaline in ultra-high pressure metamorphic rocks in Kyrgyzstan, Tienshan, and reported the boron infiltration at 70 km depth mantle.5. Fujinawa reported the metasomatism of mantle fluid in tholeiitic magma of Iwate Vol., Akita-Komagatake Vol. and Minami-Zao Vol.6. Kimura indicates the classification method based on the thermal history on parent body.7. Noguchi studied the hydration of cosmic dust using TEM, SEM and Neutron X-ray diffraction method, and found hydrous sheet silicate (saponite and serpentine).

1.Tagiri计算了糜棱岩中石英波状消光强度与石英晶格旋转角的关系。然后，Tagiri研究了变形程度与流体在糜棱岩中的渗透速度之间的关系。我们在中新世水下熔岩流中发现了硅酸盐凝胶。凝胶以每秒的速度迅速氧化。得出的结论是，在本样本的15 My期间，流体和氧气的扩散几乎为零。Tagiri和Fujinawa研究了混合岩的岩石化学转化，描述了混合岩中的熔融分离作用。4.观察了吉尔吉斯斯坦天山超高压变质岩中电气石的晶体生长，报道了70公里深地幔中硼的渗入。Fujinawa报道了岩浆中的地幔流体交代作用。和南早第6卷。木村提出了基于母体热历史的分类方法。野口用透射电子显微镜、扫描电子显微镜和中子X射线衍射法研究了宇宙尘埃的水化过程，发现了含水的片状硅酸盐(皂石和蛇纹石)。
