The Kobiwako group(late Pliocene to Pleistocene)is distributed in the Ueno and Ōmi basins, This group consists of loose sediments of gravel, silt and clay, containing the fossils of fresh-water mollusca and fossil flora. Iga-clay formation(lower part of the Kobiwako group)in Iga-basin(Shimagahara district)is one of the main fireclay producing source in Tokai region, Japan. Also, Iga-clay formation, in rich in commercial clay such as ‘Kibushi clay’and ‘Gairome clay’, which are considered as fresh-water sediments in cuncaves on granitic rocks. The name ‘Kibushi clay’is usually used for a soft and plastic underclay with lignite fragments among sedimentary fireclay. Kurosaki fireclay deposit(about 38m in depth)can be classified roughly into the following three zones: sandy clay,‘Gairome clay’, and ‘Kibushi clay’. The sandy clay predominate in the deposit, as a whole. Most of the sandy clay,‘Gairome clay’, and‘Kibushi clay’are composed mainly of kaolinite and fine-grained quartz and feldspar. Small amounts of sericite are included in some‘Kibushi clay’. The several white clay layers(about 0.5m in thick, each)are intercalated in the upper horizon of‘Kibushi clay’zone. The main constitute minerals of the white clay are smectite(montmorillonite)accompanying with kaolinite and small amount of halloysite. Also, some white clay layers are composed of amorphous substances. These white clay layers were formed diagenetically from volcanic ash, due to their mode of occurrence and mineralogical features. Furthermore, collation of the occurrence and mineralogy of clays in Kurosaki and the other fireclay deposits(Mine, Shimagahara)has been examined. MOst of the clay samples in Mine fireclay deposit are mainly composed of kaolin, quartz and feldspar. These mineral assemblages are similar to that of Kurosaki deposit. Consequently, it is considered that the sedimentary processes and origin of the fireclay deposits in these districts are mostly same conditions.@@@三重県およびその隣接する近畿県での耐火粘土鉱床は上野市を中心とする伊賀上野盆地周辺地域に多く賦存している。ここでは上野盆地の南端に位置する黒崎陶土鉱山の鉱床の産状および粘土鉱物の性状について述べる。当鉱床は領家黒雲母花崗岩を基盤とし、その凹地を埋めて堆積した伊賀粘土層といわれる花崗岩源の風化砕屑物が粘土化したもので、古琵琶湖層群の最下位の累層にあたる。鉱床は一般に砂質粘土が優位で、蛙目粘土、木節粘土、亜炭、白色粘土などの累層からなり、その最上部を砂礫層が覆っている。これらの砂質・蛙目・木節粘土層の主要鉱物はカオリナイト、石英、長石および少量のセリサイトからなる。鉱床の上位に挾在する数枚の白色粘土層には、スメクタイト（モンモリロナイト）を主として少量のハロイサイトを伴うものと、殆んど非晶質物質からなるものがあり、これらの層は火山灰源と考えている。主な粘土層のカオリナイトは不整が著しくまた結晶度も悪く、瀬戸地域も含めた他地域の同型堆積性粘土鉱床のものと殆んど同じ範囲内にある。また黒埼鉱床と上野盆地島ヶ原地域の峰陶土鉱床の構成鉱物組成、化学成分などを比較してみると、両者に大きな差異はみられない。さらに黒埼鉱山、峰陶土を含む島ヶ原地域での粘土鉱床の生成過程についても考察している。","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 Kurosaki Fireclay Deposit, Nara 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":"大森, 弘子","creatorNameLang":"ja"},{"creatorName":"Omori, Hiroko","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":"奈良県黒崎鉱山における陶土鉱床および粘度鉱物について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"奈良県黒崎鉱山における陶土鉱床および粘度鉱物について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["248"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-03-16"},"publish_date":"2018-03-16","publish_status":"0","recid":"3009","relation_version_is_last":true,"title":["奈良県黒崎鉱山における陶土鉱床および粘度鉱物について"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-11-07T04:37:59.221858+00:00"}
