The root zone dynamics under the continent collision zone. The role of crustal melting at extremely high pressure and high temperature conditions.

2002年至2004年，作为京都大学和查尔斯大学的联合项目，在捷克共和国波希米亚地块进行了三次合作野外调查，揭示了具有代表性的根带物质，如橄榄岩、酸性中麻粒岩、泥质片麻岩和以麻粒岩为主的各种类型包体的野外关系。通过上述野外调查收集的600多公斤岩石标本的室内工作揭示了以下事实和以下5个主题：1)Hirajima等人对麻粒岩峰压条件的重新评价，2)Nakamura等人于2004年在《变质岩石学杂志》上发现的超高频榴辉岩；3)Naemura等人发现的闪长石榴石橄榄岩的变质历史；4)非对称扩散…的意义Usuld等人在酸性麻粒岩中观察到了更多的织构；5)Hiroi等人观察到了剪切应力增强的Al2SiO5相的转变及其意义。等人的研究。2004年所做的进一步室内工作揭示了以下事实：6)小林在ktis的钾辉橄榄岩和混合岩的岩石学方面，7)Horny Bory的钙硅酸盐结核的P-T历史和Hisashima发现的流体包裹体，以及8)Kamei等人的Mohelno GRT-橄榄岩的P-T历史。Hirajima展示了一篇关于在佛罗伦萨举行的IGC32会议上GRT橄榄岩的P-T历史的论文，并讨论了根带物质的折返机制。利用该资金支持购买的加热台系统进行的流体包裹体研究表明，在Horny Bory钙硅酸盐结核的P-T历史中发生了多阶段的流体活动，10)Sanbagawa带地壳物质来源的石英榴辉岩含有富H2O的流体。富含H2O流体活动性的调整受到大冢和广岛详细岩石学研究的结合，2004年3月在京都召开了包括Martin Svojtka在内的指导会议，并于2004年夏季确定了活动计划。2005年3月在京都举行了总结会议，讨论了今后的计划。较少

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
