They have identical mineral compositions and petrography, confirming their pairing. The Y00 shergottites first crystallized olivine and chromite, which were then partially enclosed by low-Ca pyroxenes. Interstitial areas of melt then formed as a result of oikocryst accumulation. Plagioclase and Fe-rich pyroxene crystallized from the interstitial melt, forming the non-poikilitic basaltic areas. The cooling rate during crystallization of the basaltic area was fast enough to preserve chemical zoning within olivine and pyroxene in poikilitic areas. The Y00s have similar petrology and mineralogy to other lherzolitic shergottites: all are likely to have originated from the same igneous block on Mars. The subtle mineralogical differences that exist are probably due to spatially variable cooling rates during crystallization of the basaltic area. In terms of mineral composition, the Y00s are most similar to (although distinct from) LEW88516, Y-793605, and NWA1950. Olivine and pyroxene compositions within interstitial areas may be related to the abundance of intercumulus melt, which, as with the nakhlite case, varied spatially in the igneous block. Although the Y00s and other lherzolitic shergottites (ALH77005, LEW88516, Y-793605, GRV99027, GRV020900, and NWA1950) were located within deeper levels of the block, RBT04262, a new shergottite similar in petrology and mineralogy to lherzolitic shergottites, may have been located at a slightly shallower level characterized by abundant, evolved interstitial melts.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Y000027、Y000047、Y000097は南極で見つかった新しいレールゾライト質シャーゴッタイト火星隕石である。これらの隕石の鉱物学的・岩石学的研究の結果、３つの隕石はペアであり、これまでに見つかっているこのグループの隕石とよく似た特徴を持っていることが明らかになった。しかし、これまでのレールゾライト質シャーゴッタイトとは、鉱物組成にわずかに差が見られることから、火星の同じ岩体の少し異なった場所を起源とすると考えられる。このことから、レールゾライト質シャーゴッタイトの岩体には、ナクライトと同じように集積作用による層状分化が見られる可能性が示唆される。","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":"110006950004","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.2008.06.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2008.06.003","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":"Mikouchi, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurihara, Taichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mikouchi, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurihara, Taichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Martian meteorites","subitem_subject_scheme":"Other"},{"subitem_subject":"Lherzolitic shergottites","subitem_subject_scheme":"Other"},{"subitem_subject":"Olivine","subitem_subject_scheme":"Other"},{"subitem_subject":"Pyroxene","subitem_subject_scheme":"Other"},{"subitem_subject":"Chemical zoning","subitem_subject_scheme":"Other"},{"subitem_subject":"Martian meteorites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lherzolitic shergottites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Olivine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pyroxene","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Chemical zoning","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":"Mineralogy and petrology of paired lherzolitic shergottites Yamato 000027, Yamato 000047, and Yamato 000097: Another fragment from a Martian \"lherzolite\" block","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mineralogy and petrology of paired lherzolitic shergottites Yamato 000027, Yamato 000047, and Yamato 000097: Another fragment from a Martian \"lherzolite\" block"},{"subitem_title":"Mineralogy and petrology of paired lherzolitic shergottites Yamato 000027, Yamato 000047, and Yamato 000097: Another fragment from a Martian \"lherzolite\" block","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1364"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-15"},"publish_date":"2014-10-15","publish_status":"0","recid":"10087","relation_version_is_last":true,"title":["Mineralogy and petrology of paired lherzolitic shergottites Yamato 000027, Yamato 000047, and Yamato 000097: Another fragment from a Martian \"lherzolite\" block"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:01.640230+00:00"}
