The meaning of \"Kibushi\" in Japanese is organic substances (lignite fragments) containing clay. Mine fireclay deposit is located in western part of Shimagahara district, clay deposit of this mine can be classified into the following three zones: sandy clay zone, \"Kibushi\" clay zone and bed rock. Further, the \"Kibushi\" clay zone is divided into two sub-zones, i. e. upper sub-zone is 3.5 m thick and bluish grey and the lower one extending from the intercalated grey volcanic ash layer to 4 m in depth and showing brownish to grey in colour. A layer of greyish volcanic ash up to 1 m wide can be observed at the boundary of upper and lower \"Kibushi\" clay sub-zones. The bed rock consists of granite (Ryoke younger granite). The main constituent minerals of the \"Kibushi\" clay are kaolinite, quartz and feldspar. In the upper \"Kibushi\" clay sub-zone, sericite apper, but its appearance is not so common. Also, smectite bearing thin white clay layer is intercalated in the upper sub-zone. This white clay layer is probably an alteration product of volcanic ash. In the upper \"Kibushi\" clay sub-zone, kaolinite content is not so high but lower sub-zone, kaolinite enrichment increase with depth. Comparing the crystallinty of kaolinite in lower and upper sub-zones, X-ray peak of in lower sub-zone is shaper, which seems to be caused by its better crystallising property. Therefore, kaolinite in the lower sub-zone consider to reflect a greater degree of clayey state than those in the upper sub-zone. Further, sampling of \"Kibushi\" clay from Inzo mine, Seto district, Aichi Prifecture have been examined. Indentified minerals of the \"Kibushi\" clay in Inzo mine are mainly kaolinite, quartz and feldspar, and small amounts of sericite. Comparing with the feature of \"Kibushi\" clay in Inzo and Mine mine, it is hard to distinguish the mineral component.@@@三重県の耐火粘土鉱床は上野市を中心とする伊賀地方に数ヶ所賦存している。これらのうち島ヶ原地域の峰陶土鉱床の産状について述べる。当地域は領家花崗岩の基盤の凹所に伊賀粘土層が堆積したもので、鉱床のプロファイルは下位から上位にかけて砂質粘土をレンズ状に挾む褐色～灰色木節粘土層、灰白色火山灰層、炭質物を多く含む青灰色木節粘土層、砂質粘土層が整合に堆積し、最上部を砂礫層が不整合に覆うている。この木節粘土層は灰白色火山灰層を境としてその産状、鉱物組成などから上下2層に区分できる。両層の木節粘土に含まれる主な構成鉱物は、石英、長石、カオリナイトで、上部粘土層にはセリサイトがみられる。また上部木節粘土層の上位に火山灰源と思われるスメクタイトを含む白色粘土層を挾む。木節粘土層中のカオリナイトは不整が著しくまた結晶度も悪い。さらに峰陶土と瀬戸地区印所鉱山の木節粘土の構成鉱物の性状を比較してみると、両者ともその組成鉱物の組合せに大差はみられない。","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学教育学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-9225","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00234199","subitem_source_identifier_type":"NCID"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Mineralogical Studies on the Occurrence of Mine Fireclay Deposit, Shimagahara, Mie Prefecture"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"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":"小倉, 義雄","creatorNameLang":"ja"},{"creatorName":"Ogura, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中原, 美保","creatorNameLang":"ja"},{"creatorName":"Nakahara, Miho","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"下坂, 康哉","creatorNameLang":"ja"},{"creatorName":"Shimosaka, Koya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"三重県島ヶ原地域の峰陶土鉱床の産状および粘度鉱物について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"三重県島ヶ原地域の峰陶土鉱床の産状および粘度鉱物について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["247"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-03-16"},"publish_date":"2018-03-16","publish_status":"0","recid":"2999","relation_version_is_last":true,"title":["三重県島ヶ原地域の峰陶土鉱床の産状および粘度鉱物について"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-11-07T04:27:28.291917+00:00"}
