(1971). However, there are important events, issues, and data related to this discovery that have so far not been published. Prior to the author's departure for Antarctica, M. Gorai suggested the author to consider collecting meteorites during the trip. On 21 December 1969, when geodetic measurements for the 250 km span of a triangulation chain were approaching its completion, members of the inland survey team collected three stones on the surface of the ice sheet in the southeastern marginal area of the Yamato Mountains. The author realized that these rocks were possibly meteorites, recalled the suggestion by M. Gorai, and requested all members of the team to collect other possible meteorites while conducting the geodetic survey. After returning to Japan, the nine stones collected in Antarctica were all identified as meteorites by M. Gorai. The concept of a mechanism by which meteorites became concentrated in the area in which they were found, involving the flow, structure, and ablation of the ice sheet, was developed in the field in 1969 during the collection program, and was mentioned briefly in Yoshida et al. (1971); a schematic figure was shown in a Japanese newspaper in the same year. With all these as background, further collections of meteorites in the Yamato Mountains were conducted in the 1973 and 1974–1975 seasons, and a project involving the collection of meteorites was formally incorporated as an important component of the work undertaken by the geology group within JARE from the 1975–1976 season onwards.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"第十次日本南極地域観測隊の内陸調査隊は、1969年12月にやまと山脈東南縁の裸氷帯で9個の隕石を発見・採集した。これはやまと隕石の最初の発見であり、これがきっかけとなって今日までに南極から45000個を越える膨大な量の隕石が収集され、世界全体の収集隕石数の大部分を占めるようになった。最初の発見のきっかけは、氷床の測量作業中に数人の調査員が偶然に3個の岩石を採集したことであったが、その後は測量のルート上で採集作業が意図的に行なわれた。報告では、日本出発前に隊員に対して行なわれたシニア科学者による隕石採集の示唆、現地での発見と採集作業の詳細、現地及び日本における隕石集積機構の考察、日本での隕石の確認と発表の事情等を、当時の写真や関係者間の手紙等と共に明らかにした。","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":"110007569044","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.2009.11.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2009.11.001","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":"Yoshida, Masaru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshida, Masaru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Meteorite","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamato Mountains","subitem_subject_scheme":"Other"},{"subitem_subject":"Meteorite search","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamato Meteorites","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctic Meteorites","subitem_subject_scheme":"Other"},{"subitem_subject":"Meteorite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamato Mountains","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Meteorite search","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamato Meteorites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctic Meteorites","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":"Discovery of the Yamato Meteorites in 1969","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Discovery of the Yamato Meteorites in 1969"},{"subitem_title":"Discovery of the Yamato Meteorites in 1969","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1361"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-15"},"publish_date":"2014-10-15","publish_status":"0","recid":"10121","relation_version_is_last":true,"title":["Discovery of the Yamato Meteorites in 1969"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:11.122189+00:00"}
