<▼1><P>HIZEN celadon glazes produced in 1630's to 1790's (Edo period, Japan) have been investigated by means of X-ray absorption spectra (XAS) near a Fe-K edge by using synchrotron radiation and a Mössbauer spectrum. The XAS suggest that the local structure around Fe2O3 fine powders is slightly different between the Izumiyama ceramics of mainly the Quartz-SiO2 and Ohkawachi ceramics of mainly the feldspar of (K,Na)Si3O8 (Sanidine), and that the glazes of the HIZEN celadons include the Fe2O3 fine powders in the glassy state, though the X-ray diffraction patterns of the glassy celadon glazes do not show any peaks of the Fe2O3 structure. The Mössbauer spectrum suggests that the celadon glaze of Seiji (m) includes only Fe3+ ions, but not Fe2+ ions. This indicates the existence of Fe2O3 in the celadon glaze. It is interpreted that the colored brightness of the HIZEN celadons is induced by the structural properties of the used raw celadon ceramics and the other transition-metal ions of Cr, Cu, Zn in the celadon glazes, but not by the chemical reaction from Fe2O3 to FeO under the deoxidizing thermal treatment at higher temperature in a kiln.</P></▼1><▼2><P>Esmaltes de celadon Hizen produzidos dos anos 1630 a 1790 (período Edo, Japão) foram investigados por meio de espectros de absorção de raios X (XAS) próximos da linha Fe-K usando radiação síncrotron e espectro Mossbaues. Os resultados de XAS sugerem que a estrutura local em pós finos de Fe2O3 é levemente diferente entre as cerâmicas Izumiyama principalmente o quartzo e cerâmicas Ohkawachi principalmente do feldspato (K,Na)Si3O8 (Sanidine), e que os esmaltes dos celadons Hizen incluem finos pós de Fe2O3 no estado vítreo, embora os difratogramas de raios X dos esmaltes celadon não mostrem picos da estrutura do Fe2O3.

The double differential thick target neutron yields from 9 MeV deuteron incidence were measured at the Kyushu University Tandem Accelerator Laboratory. A copper and a titanium foils which are thick enough for a deuteron to stop in the foils were placed at the center of a vacuum chamber. An NE213 liquid organic scintillator was employed to detect neutrons emitted from targets and placed at 9 directions from 0˚ to 140˚. To consider the contribution of scattered neutrons from the floor, we also measured neutron yields with an iron shadow bar located in front of the scintillator. Because incident deuteron beam was not pulsed and the Time-of-Flight method was not applied, the energy spectrum was derived from unfolding the light output spectrum using the FORIST code. The detection efficiency was calculated with the SCINFUL-QMD code. The experimental results were compared with the calculation data of the TALYS code, and it turned out that the calculation data does not reproduce the experimental ones satisfactorily.

<▼1><P>Kakiemon-style porcelains produced at Arita areas (SAGA) in Kyushu Island are famous Japanese porcelains. The porcelain-techniques creating its elegant and bright red-color underglaze and overglaze were found and developed in 1650's (early Edo period) first by Kakiemon kiln. Red-color overglaze and transparent glaze of the Kakiemon-style porcelains have been investigated by means of X-ray diffraction using synchrotron radiation. The results suggest that the red-color brightness is mainly induced by micro-structural correlation between α-Fe2O3 fine particles, as red-color emission elements, and other oxides of SiO2, Al2O3, CaO, KNaO, PbO. The stability of the red-overglaze on the porcelain surface is related to interfacial fusion of the glasses existing in the fritted red-overglaze and the transparent glaze on the porcelain body. The ancient porcelain-techniques of the Kakiemon-style porcelains are clearly based on the micro-structural and material properties of the overglazes, the underglazes, and the transparent glazes, though the techniques were experimentally and accidentally found and developed in the Edo period.</P></▼1><▼2><P>As porcelanas do estilo Kakiemon produzidas nas áreas de Arita (SAGA) na ilha Kyushu são porcelanas japonesas famosas. As técnicas de produzir porcelanas com os elegantes e brilhantes vidrados de cores vermelho brilhante foram encontradas e desenvolvidas nos anos 1650 (início do período Edo) primeiramente em fornos Kakiemon. Vidrados vermelhos e vidrados transparentes de porcelanas do estilo Kakiemon foram investigadas por meio de difração de raios X com radiação sincrotron. Os resultados sugerem que o brilho de cor vermelha é principalmente induzido pela correlação microestrutural entre finas partículas de α-Fe2O3, como elementos emissores de cor vermelha, além de outros óxidos como SiO2, Al2O3, CaO, KNaO, e PbO. A estabilidade dos vidrados na superfície da porcelana com vidrado vermelho está relacionada com a fusão interfacial dos vidros existentes no vidrado vermelho calcinado e o vidrado transparente do corpo da porcelana. As antigas téncias de porcelana do estilo Kakiemon são claramente baseadas nas propriedades microestruturais do material dos vidrados sobrepostos, os sub-postos e os transparentes, embora as técnicas tenham sido encontradas e desenvolvidas experimental e acidentalmente no período Edo.</P></▼2>
Horie, K.,Yamashita, M.,Hayasaka, Y.,Katoh, Y.,Tsutsumi, Y.,Katsube, A.,Hidaka, H.,Kim, H.,Cho, M. Elsevier Scientific Pub. Co., etc.] 2010 Precambrian research Vol.183 No.1
U-Pb zircon geochronology of two Permo-Triassic granites (samples OT-52 and OT-272 with ages of 229+/-8Ma and 256+/-2Ma, respectively) in the Unazuki area, Hida Metamorphic Belt, southwest Japan, revealed the presence of Eoarchean to Paleoproterozoic inheritance. Inheritance is consistent with both samples showing low zircon saturation temperatures for their bulk compositions. In OT-52, dark in CL, low Th/U zircon domains have a mean <SUP>207</SUP>Pb/<SUP>206</SUP>Pb age of 1940+/-17Ma, which is consistent with an age of 1937+/-6Ma for anatexis in the Precambrian Busan gneiss complex in Korea. Eoarchaean inherited zircons with <SUP>207</SUP>Pb/<SUP>206</SUP>Pb ages from ca. 3750 to 3550Ma are common in OT-272 but are few in OT-52, suggesting a source from rocks with affinities to those in the Anshan area in the northeast China part of the North China Craton. On the other hand, a Hida Metamorphic Belt metasedimentary gneiss into which the granites were intruded contains ca. 1840, 1130, 580, 360, 285 and 250Ma zircons (Sano et al., 2000). These ages suggest that the Unazuki Mesozoic granites did not originate from proximal Hida Metamorphic Complex rocks, but instead from unrelated rocks obscured at depth. The predominance of Eoarchean to Paleoproterozoic age components, and the marked lack of 900-700Ma components suggest that the source was the (extended?) fringe of the North China Craton, rather than from Yangtze Craton crust. The Mesozoic evolution of Japan and its linkages to northeast Asia are discussed in the context of these results.
