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计算了石英的波浪形灭绝强度与肌lon虫中石英晶体的旋转角之间的关系。然后，塔吉里研究了甲状腺菌中流体的变形度与渗透速度之间的关系。2。我们在中新世下湖中发现了硅酸盐凝胶。凝胶以每秒速度氧化很快。它得出结论，在该样品中15My期间流体和氧扩散几乎为零。3。 Tagiri和Fujinawa研究了Migmatites的石化转化，并描述了Migmatites中恢复材料的融化分离。4。我们观察到了超高压变态岩石在吉尔吉斯斯坦，Tienshan，Tienshan和Tienshan，tienshan和Tieenshan和Tieenshan，Tienshan，and Tienshan及其报告中的高压变态岩石中tourmaline的晶体生长，并报道了在70 kmmeron的渗漏量。藤原报道了ikita-komagatake vol。和Minami-Zao第6卷。木村指示基于母体的热史的分类方法7。 Noguchi使用TEM，SEM和中子X射线衍射方法研究了宇宙粉尘的水合，并找到了含水片硅酸盐（皂石和蛇纹石）。
