Y-791088, which consists of numerous coarse-grained relict phases (40%) and euhedral fine-grained minerals solidified from the shock melt (60%), experienced incomplete melting; a quiescent melt is indicated by the existence of abundant relict phases, pseudomorphed chondrules, and two types of glass. LAP 02240, which consists of small amounts of coarse-grained relict phases (10%) and fine-grained minerals (90%), experienced near-complete melting; a rapidly cooled mobilized melt is indicated by the homogeneous compositions of glass and opaque veins.The homogeneous compositions of relict olivines indicate that the precursors of both chondrites were equilibrated H chondrites. The melting features of Y-791088 and LAP 02240 are very similar to those of Y-790964 (LL) and the fine-grained lithology of Y-790519 (LL), respectively. These two types of shock-melted ordinary chondrites possibly formed in situ during dike formation. The quiescent melt is thought to have originated from the injection of shock-heated chondrite blocks into mobilized melt. These two types of melting could have occurred during dike formation on the H chondrite parent body. The textures of the two types of shock melts were not simply affected by the degree of shock melting: they were also controlled by the degree of shear stress.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"異なる特徴を持つHコンドライトの衝撃溶融岩（Y-791088およびLAP 02240）を、岩石・鉱物学的視点から比較し、形成環境を検討した。Y-791088は，とけ残り物質を約40％含み，コンドルールの形態を保持している。一方、LAP 02240は約10％のとけ残り物質を含み、コンドルールは変形している。同様の特徴はLLコンドライトの衝撃溶融岩である、Y-790964およびY-790519で観察される。Y-790519では、２つの衝撃溶融岩相が共存しており、両岩相が同時に形成したことを示している。異なる衝撃溶融岩の特徴は、溶融度の違いのみではなく、加わった剪断応力の差を反映していると考えられる。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110007873827","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2010.08.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.08.003","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Takafumi, Niihara"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Naoya, Imae"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Keiji, Misawa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hideyasu, Kojima"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takafumi, Niihara","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Naoya, Imae","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Keiji, Misawa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hideyasu, Kojima","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Y-791088","subitem_subject_scheme":"Other"},{"subitem_subject":"LAP 02240","subitem_subject_scheme":"Other"},{"subitem_subject":"Ordinary chondrite","subitem_subject_scheme":"Other"},{"subitem_subject":"Shock melt","subitem_subject_scheme":"Other"},{"subitem_subject":"Petrogenesis","subitem_subject_scheme":"Other"},{"subitem_subject":"Y-791088","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LAP 02240","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ordinary chondrite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Shock melt","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Petrogenesis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Petrology and mineralogy of the shock-melted H chondrites Yamato-791088 and LaPaz Ice Field 02240","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Petrology and mineralogy of the shock-melted H chondrites Yamato-791088 and LaPaz Ice Field 02240"},{"subitem_title":"Petrology and mineralogy of the shock-melted H chondrites Yamato-791088 and LaPaz Ice Field 02240","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1357"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10200","relation_version_is_last":true,"title":["Petrology and mineralogy of the shock-melted H chondrites Yamato-791088 and LaPaz Ice Field 02240"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:45.124373+00:00"}
