项目摘要

Co-operative field survey in the Bohemia massif Czech Republic, has been carried out three times as the joint project between Kyoto University and Charles University from 2002 to 2004, and the field relationships of the representative root zone materials, such as peridotite, acidic-intermediate granulite, pelitic gneiss and various type xenoliths mainly hosted by granulite, have been revealed.In-door work for more than 600kg rock specimens collected by the field survey mentioned above revealed following facts and following 5 topics of them were shown in the annual meeting of Japanese Geological Society at Shizuoka University in 2003 : 1)Re-evaluation of Peak pressure conditions for granulite by Hirajima et al., 2)Finding of UHF eclogite from Nave Dvory peridotite body by Nakamura et al., which issue has been published in Journal of metamorphic Petrology in 2004, 3)Metamorphic history of garnet peridotite at Plesovice quarry by Naemura et al., 4)A significance of un-symmetric diffusion … More texture observed in acidic granulite by Usuld et al., and 5)Transformation of Al2SiO5 phases enhanced by shear stress and its significance by Hiroi. et al. Further In-door work done in 2004 revealed following facts ; 6)Petrological aspect of kinzigite and migmatite at Ktis by Kobayashi, 7)P-T history of calc-silicate nodule at Horny Bory and the finding of fluid inclusion by Hisashima, and 8)P-T history of Mohelno Grt-peridotite by Kamei et al.. Hirajima showed a paper on the P-T history of Grt peridotite at IGC32 held in Florence and discuss the exhumation mechanism of the root zone materials.Fluid inclusion study using the heating stage system purchased by this financial support revealed 9)Multi-stage fluid activities took place in the P-T history of Horny Bory calc-silicate nodule and 10)Quartz eclogite derived from crustal materials in the Sanbagawa belt contains H2O-rich fluid. The tuning of H2O-rich fluid activity have been constrained by the combination of detailed petrological study by Ohtsuka and Hirajima Steering meeting was held in March 2004 including Martin Svojtka at Kyoto and determined the active plan in summer of 2004. Summarizing meeting was held in March 2005 at Kyoto and discussed future plan. Less

波西米亚地块捷克共和国的合作现场调查是在2002年至2004年的京都大学查尔斯大学之间的联合项目中进行的，并且代表了根部区域材料，例如橄榄岩，橄榄岩，橄榄石，野生矿石经过以下事实所述的现场调查收集的花岗岩，鞘岩和各种K标本，并在2003年在Shizuoka University的日本地质学会的年度肉类肉类肉类上进行了5个主题：1）重新评估Hirajima颗粒的峰值压力条件的重新评估等等。 usuld等人，以及5）Al2SIO5阶段的转化是通过hiroi及其在Kobayashi的kinzigite和Migmatite方面增强的。 8）Kamei等人的p-Thelno grt-卵石。在角质Bory的P-T历史上计算硅酸盐结节10）源自Sanbagawa Belt中的地壳的石英纤维岩含有富含H2O的液体的含量。 2004年3月在京都举行的包括马丁·斯沃伊特卡（Martin Svojtka），并确定2004年夏季的积极计划在2005年3月在京都举行，并讨论了未来的计划
