It is significantly dismembered, being composed of peridotites, isotropic gabbro, dolerite dikes and volcanic rocks. The rocks are highly altered or metamorphosed. Completely serpentinized harzburgite with strong foliation comprises the mantle section of the ophiolite. Small amount of dunite and pyroxenite are concordant and discordant, respectively. Small concordant chromitite pods are not rare. Dunite is predominate near the contact with the gabbroic section, having frequent gabbroic bands. This lithology is equivalent to the Moho transition zone. Relic textures and spinel chemistry constrained initial lithology and chemical characteristics of the peridotites. The Cr# of spinet is >0.6 in harzburgite and >0.7 in chromitite, indicating a refractory character of the mantle section of the Bou-Azzer ophiolite. Late-intrusive wehrlite was found in the gabbroic rocks. Constituent rocks are basically similar to those in the Phanerozoic ophiolites, such as the Oman ophiolite, except for the refractory character of the mantle section. The highly refractory character of the mantle section may be one of characteristics of the Proterozoic ophiolite.\nTo be interesting, secondary clots or veins of magnetite (sometimes Ni-bearing) are common to the serpentinized harzburgite. Secondary chromian spinels with appreciable amounts of Mn, Co and Ni are occasionally found in harzburgite. These elements were expelled from olivine upon serpentinization because serpentine minerals are low in them relative to olivine. They are mobile and could precipitate to form magnetite clots/veins of were incorporated in chromian spinels. The mobility of these elements are possibly related to precipitation as ores (arsenides) (= Bou-Azzer Co ores) around the boundary of the ophiolitic serpentinite.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:16403010, 研究期間(年度):2004-2006","subitem_description_type":"Other"},{"subitem_description":"出典：「原生代ボウ・アゼールオフィオライト(モロッコ)調査」研究成果報告書　課題番号16403010\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052622","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学国際基幹教育院GS教育系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=20107684"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=20107684","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16403010/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16403010/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16403010/164030102006kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16403010/164030102006kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-01"}],"displaytype":"detail","filename":"SC-PR-ARAI-S-kaken 2007-13p.pdf","filesize":[{"value":"247.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-ARAI-S-kaken 2007-13p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46289/files/SC-PR-ARAI-S-kaken 2007-13p.pdf"},"version_id":"f429741e-2f0c-4f99-801b-23b7c38fb6ec"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"原生代ボウ・アゼールオフィオライト(モロッコ)調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"原生代ボウ・アゼールオフィオライト(モロッコ)調査"},{"subitem_title":"Oversea Research on the Bou-Azzer Ophiolite (Morocco) of Proterozoic Age","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2827"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-01"},"publish_date":"2018-11-01","publish_status":"0","recid":"46289","relation_version_is_last":true,"title":["原生代ボウ・アゼールオフィオライト(モロッコ)調査"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:34:02.221530+00:00"}
