The phase boundary between zircon and reidite was determined to be P (GPa) = 8.5 + 0.0017~(T-1200) (K) for temperatures between 1100-1900 K. When subducted slabs, including igneous rocks and sediments, descend into the upper mantle, zircon in the subducted slab transforms into reidite at pressures of about 9 GPa, corresponding to a depth of 270 km. Reidite found in an upper Eocene impact ejecta layer in marine sediments is thought to have been transformed from zircon by a shock event. The peak pressure generated by the shock event in this occurrence is estimated to be higher than 8 GPa. en-copyright= kn-copyright= en-aut-name=OnoShigeaki en-aut-sei=Ono en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunakoshiKenichi en-aut-sei=Funakoshi en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakajimaYoichi en-aut-sei=Nakajima en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TangeYoshinori en-aut-sei=Tange en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuraTomoo en-aut-sei=Katsura en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Institute for Frontier Research on Earth Evolution, Japan Marine Science & Technology Center affil-num=2 en-affil= kn-affil=Japan Synchrotron Radiation Research Institute affil-num=3 en-affil= kn-affil=Department of Earth and Planetary Sciences, Tokyo Institute of Technology affil-num=4 en-affil= kn-affil=Department of Earth and Planetary Sciences, Tokyo Institute of Technology affil-num=5 en-affil= kn-affil=Institute for Study of the Earth's Interior, Okayama University en-keyword=high-pressure phase kn-keyword=high-pressure phase en-keyword=kokchetav massif kn-keyword=kokchetav massif en-keyword=northern KAZAKSTAN; METAMORPHIC ROCKS; ZRSIO4; TRANSFORMATIONS; POLYMORPH; REIDITE; STATE; GPA kn-keyword=northern KAZAKSTAN; METAMORPHIC ROCKS; ZRSIO4; TRANSFORMATIONS; POLYMORPH; REIDITE; STATE; GPA END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=2 article-no= start-page=367 end-page=368 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antibiotic sensitivity of bacteria on the oral mucosa after hematopoietic cell transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SogaYoshihiko en-aut-sei=Soga en-aut-mei=Yoshihiko kn-aut-name=]䌫F kn-aut-sei=] kn-aut-mei=F aut-affil-num=1 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EbinumaTakayuki en-aut-sei=Ebinuma en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaHiroshi en-aut-sei=Maeda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Division of Hospital Dentistry, Central Clinical Department, Okayama University Hospital affil-num=2 en-affil= kn-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Pathophysiology?Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences END
