Although dynamic crystallization experiments are useful for estimating the cooling rate, experimental results only show the possibility of the cooling rate. It is, therefore, important to determine the cooling rate of actual olivines in rocks. We applied our model to calculating the cooling rate for olivines of type II porphyritic olivine chondrules in the Semarkona (LL 3.00) ordinary chondrite. The cooling rates show a wide range from 0.8 C/h to 2400 C/h for olivines in different chondrules. Although these results are broadly consistent with those obtained by dynamic crystallization experiments, the lower limit of the calculated cooling rate, 0.8 C/h, is about one order magnitude slower than experimental results. Our result suggests that each chondrule formed in different environmental conditions and assembled in Semarkona after chondrule formation.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064291036","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12268968","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院理学系研究科地球惑星科学専攻宇宙惑星科学講座"},{"subitem_text_value":"東京大学大学院理学系研究科地球惑星科学専攻宇宙惑星科学講座"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Space and Planetary Science, Graduate School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Space and Planetary Science, Graduate School of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, University of New Mexico"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宮本, 正道"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三河内, 岳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyamoto, Masamichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mikochi, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jones, R.
