Rocks exposed in the vicinity of Sagata are dominantly Neogene and younger volcanic rocks (mainly andesites). The cave, investigated in this study, is formed within the andesite. The siliceous protrusions, ranging in size from 2 mm to 1.5 cm, have been grown on the andesite surface in random orientations. Microscopic observations of the protrusions show concentric zones indicating their progressive growth or precipitation. X-Ray elemental mapping showed the protrusions are characterized by Si and variable amounts of Fe. The structure of the protrusions resembles to those of the stalactites/stalagmites generally found in limestone caves but their chemical composition is dominantly Si- and Fe-rich without significant amount of Ca or Na that indicate non-involvement of saline water. Petrographic and chemical analysis showed the presence of amorphous silica, cristobalite, hornblende along with some mixed peaks of clay minerals suggesting their growth from the andesite through secondary alteration.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13456938","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11246904","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"450","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"レーマン, ハフィーズウル","creatorNameLang":"ja"},{"creatorName":"REHMAN, Hafiz Ur","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"大木, 公彦","creatorNameLang":"ja"},{"creatorName":"OKI, Kimihiko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"高橋, 智哉","creatorNameLang":"ja"},{"creatorName":"TAKAHASHI, Tomoya","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-26"}],"displaytype":"detail","filename":"AA11246904_v53_p25-31.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11246904_v53_p25-31","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/15664/files/AA11246904_v53_p25-31.pdf"},"version_id":"2d736d3e-a94e-40b8-b6a1-ddc389451840"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Siliceous protrusions","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"amorphous silica","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"halloysite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrothermal process","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Akune","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sagata cave","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"鹿児島県阿久根市佐潟洞窟内のシリカ突起物","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鹿児島県阿久根市佐潟洞窟内のシリカ突起物","subitem_title_language":"ja"},{"subitem_title":"Siliceous protrusions in the Sagata Cave, Akune city, Kagoshima Prefecture","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["53","5997"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-01-26"},"publish_date":"2021-01-26","publish_status":"0","recid":"15664","relation_version_is_last":true,"title":["鹿児島県阿久根市佐潟洞窟内のシリカ突起物"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-08T04:49:24.451687+00:00"}
