The subdivision was based on the assumption that metamorphism occurred at ca. 116 Ma, largely based on an early Rb-Sr isotope study and zircon data obtained for the eclogite unit of the Sanbagawa Belt, whereas in some parts of the belt detrital zircons of late Cretaceous age (90-80 Ma) were discovered. Analysis of detrital zircons sampled from two sites within the area considered to expose the older ‘Sanbagawa Metamorphic Rocks’, including the area investigated by the Rb-Sr study, reveals the presence of zircons younger than 95 Ma in all samples and some grains as young as 80 ± 4 Ma. It is therefore concluded that the Sanbagawa Belt is one single tectonic entity that formed in the Late Cretaceous though it contains older components, including fossiliferous clasts, older basic meta-volcanics and eclogite units that may record earlier metamorphic events. en-copyright= kn-copyright= en-aut-name=KnittelUlrich en-aut-sei=Knittel en-aut-mei=Ulrich kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WaliaMonika en-aut-sei=Walia en-aut-mei=Monika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeeYuan-Hsi en-aut-sei=Lee en-aut-mei=Yuan-Hsi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Clay and Interface Mineralogy, RWTH Aachen University kn-affil= affil-num=2 en-affil=Department of Geosciences, National Taiwan University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth and Environmental Sciences, National Chung-Cheng University kn-affil= en-keyword=U-Pb zircon dating kn-keyword=U-Pb zircon dating en-keyword=Sanbagawa Metamorphic Belt kn-keyword=Sanbagawa Metamorphic Belt en-keyword=Late Cretaceous kn-keyword=Late Cretaceous en-keyword=Asemi River kn-keyword=Asemi River END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=31 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new method of terrace analysis to determine precise altitudes of former shoreline en-subtitle= kn-subtitle= en-abstract= kn-abstract= The study area is situated in Japan Sea side margin of the Shakotan Peninsula, Hokkaido, Japan, where MIS5e Terrace is preserved along the cost. Numbers of tight drilling have done to establish new method for terrace analysis. Buried wave cut terrace and sea cliff (when the MIS5e Terrace was formed) are reconstructed by distribution of the terrace deposits and these bottom of unconformity planes. The precise site and altitude of former shoreline was also obtained. Altitudes of the former shoreline from the 7 sections are almost the same 22 to 27m in height. Previous data of the height of shoreline are obtained from the topographic MIS5e Terrace surface. The altitudes have variation from 30m to 60m. It suggests that the traditional method for the MIS5e terrace analysis had some errors in the study area. en-copyright= kn-copyright= en-aut-name=AmanoHideki en-aut-sei=Amano en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoMasaru en-aut-sei=Sato en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanagidaMakoto en-aut-sei=Yanagida en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Hanshin Consultants Co., Ltd., kn-affil= affil-num=4 en-affil=Hanshin Consultants Co., Ltd., kn-affil= en-keyword=MIS5e kn-keyword=MIS5e en-keyword=marine terrace kn-keyword=marine terrace en-keyword=terrace deposits kn-keyword=terrace deposits en-keyword=tight drilling kn-keyword=tight drilling en-keyword=shoreline kn-keyword=shoreline END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=19 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of an interdisciplinary study plan on the seasonal transition from autumn to winter around the Japan Islands (Through the lesson study at junior high school with attention to the shallow convective rainfall “Shi-gu-re” in the cold air outbreak situations in early winter) kn-title=日本の秋から冬への季節の変化を捉える学際的指導法の開発(初冬の時雨に注目した附属中学校での実践) en-subtitle= kn-subtitle= en-abstract= kn-abstract= An interdisciplinary study plan on the seasonal transition from autumn to winter around the Japan Islands and the “seasonal feeling” associated with the shallow convective rainfall “Shi-gu-re” in that stage expressed in the Japanese classic poems called “Wa-ka” was developed, through a lesson study at junior high school. In that study plan, special attention was paid to the seasonal evolution of the larger-scale systems from autumn to winter, such as the Siberian air mass and the Siberian high, and the relation to the cold air intrusion into the Japan Sea and the Japan Islands. According to the analysis of the lesson practice results, students seem to understand that the winter-type weather pattern becomes dominant around November, together with the features of the intermittent rainfall in the winter-type pressure pattern called “Shi-gu-re” expressed in the “Wa-ka”. However, necessity of further improvement of the study plan was pointed out, so that the students can understand more exactly the role of the seasonal development of the Siberian high and Siberian air mass in the climate around the Japan Islands. en-copyright= kn-copyright= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=NishikawaSari en-aut-sei=Nishikawa en-aut-mei=Sari kn-aut-name=西川紗里 kn-aut-sei=西川 kn-aut-mei=紗里 aut-affil-num=2 ORCID= en-aut-name=NakakuraToshimi en-aut-sei=Nakakura en-aut-mei=Toshimi kn-aut-name=中倉智美 kn-aut-sei=中倉 kn-aut-mei=智美 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Attached Junior High School of Okayama University kn-affil=岡山大学教育学部附属中学校 en-keyword=Interdisciplinary collaboration between climate and cultural understanding education kn-keyword=Interdisciplinary collaboration between climate and cultural understanding education en-keyword=Climate environment around Japan kn-keyword=Climate environment around Japan en-keyword=Transition from autumn to winter around Japan kn-keyword=Transition from autumn to winter around Japan en-keyword=“Seasonal feeling” in early winter expressed in the Japanese classic literature kn-keyword=“Seasonal feeling” in early winter expressed in the Japanese classic literature en-keyword=ESD kn-keyword=ESD END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=7 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Synoptic climatological analyses on the large day-to-day variation of air temperature around Germany in winter (Relating to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away) kn-title=ドイツ付近の冬における日々の大きな気温変動に関する総観気候学的解析(冬の追い出しの行事「ファスナハト」における季節感に関連して) en-subtitle= kn-subtitle= en-abstract= kn-abstract= Synoptic climatological analyses associated with the large day-to-day variation of air temperature around Germany in winter were performed based mainly on the NCEP/NCAR reanalysis data for 2000/2001 to 2010/2011 winters, with an interest in the relationship to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away. The intermittent appearance of the extremely cold days with rather large day-to-day variation in winter as pointed out by Kato et al. (2017) for around Germany was seen also to the north and to the east of Germany. According to a case study for the 2000/2001 winter, such large daily mean temperature fluctuation was closely related to the intraseasonal variation of the Icelandic low with about one month period, i.e., while the temperature around Germany was relatively higher at the eastward shift phase of the Icelandic low due to the strong warm air advection by the SW-ly wind, the temperature was extremely low there when the Icelandic low was weakened and retreated westward. en-copyright= kn-copyright= en-aut-name=HamakiTatsuya en-aut-sei=Hamaki en-aut-mei=Tatsuya kn-aut-name=濱木達也 kn-aut-sei=濱木 kn-aut-mei=達也 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=OtaniKazuo en-aut-sei=Otani en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= en-aut-name=KatoHaruko en-aut-sei=Kato en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=4 ORCID= en-aut-name=MatsumotoKengo en-aut-sei=Matsumoto en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) affil-num=4 en-affil=Faculty of Education, Gifu Shotoku Gakuen University kn-affil=岐阜聖徳学園大学教育学部 affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Comparative climatology kn-keyword=Comparative climatology en-keyword=Climate around Europe kn-keyword=Climate around Europe en-keyword=Synoptic climatology on daily temperature variation in winter around Germany kn-keyword=Synoptic climatology on daily temperature variation in winter around Germany en-keyword=seasonal cycle and “seasonal feeling” kn-keyword=seasonal cycle and “seasonal feeling” END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Non-calcareous beachrock found in Akagurisaki, Ohi Town, Fukui Prefecture kn-title=福井県おおい町赤礁崎で見出された非石灰質ビーチロック en-subtitle= kn-subtitle= en-abstract= kn-abstract= Beachrock which was formed about 0.5 meter higher than high tide is found in Akagurisaki, Ohi Town, Fukui Prefecture. The outcrops always get wet by spring water. The sediments are composed of well sorted rounded gravels and sands but calcareous shell is not found at all. Intergranular space is occupied by white amorphous cement. Magnesium and silicon rich composition of the cement is obtained by EPMA analysis. There is a conjecture that the magnesium rich cement was precipitated in spite of solution of calcareous shell under saturated state by spring water, because calcium has a higher tendency to ionize than magnesium. en-copyright= kn-copyright= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=1 ORCID= en-aut-name=AzumaYoichi en-aut-sei=Azuma en-aut-mei=Yoichi kn-aut-name=東洋一 kn-aut-sei=東 kn-aut-mei=洋一 aut-affil-num=2 ORCID= en-aut-name=DeyamaYasuyo en-aut-sei=Deyama en-aut-mei=Yasuyo kn-aut-name=出山康代 kn-aut-sei=出山 kn-aut-mei=康代 aut-affil-num=3 ORCID= en-aut-name=YukawaHirokazu en-aut-sei=Yukawa en-aut-mei=Hirokazu kn-aut-name=湯川弘一 kn-aut-sei=湯川 kn-aut-mei=弘一 aut-affil-num=4 ORCID= en-aut-name=UsuiMayumi en-aut-sei=Usui en-aut-mei=Mayumi kn-aut-name=臼井まゆみ kn-aut-sei=臼井 kn-aut-mei=まゆみ aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=平寺町松岡兼定島 4-1-1 ** kn-affil=福井県立大学恐竜学研究所 affil-num=3 en-affil=平寺町松岡兼定島 4-1-1 ** kn-affil=福井県立大学恐竜学研究所 affil-num=4 en-affil=Fukui Prefectural Dinosaur Museum kn-affil=福井県立恐竜博物館 affil-num=5 en-affil=Fujigakuin-Okayama kn-affil=富士学院 en-keyword=Beachrock kn-keyword=Beachrock en-keyword=Akagurisaki kn-keyword=Akagurisaki en-keyword=non-calcareous cement kn-keyword=non-calcareous cement en-keyword=ionization tendency kn-keyword=ionization tendency END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END
