Various rocks and minerals are examined for their reactivity with CO2. The silicates are crushed gently in a big ball mill with mixed gas of 10% CO2 and 90% N2. Residual gas is monitored by a gas-chromatograph. The 0.03 mol of C02 in the mill are experimentally found to react in one hour with one mol olivine and peridotite. The quick reaction of CO2 and fresh surface of peridotite is also expected in natural environments. Artificially processed rock with fresh surface like historical statue and building might adsorb atmospheric CO2 at that time of construction and react quickly. If the altered surface preserve the gas-rock chemistry at that time, it is considered that the surface must be a possible subject of 14C dating for the surface processing.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"二酸化炭素は、岩石・鉱物の破砕に伴い、苦鉄質鉱物と急速に反応する。本研究では、多様なケイ酸塩鉱物/岩石と二酸化炭素の反応性を様々な条件で比較検討した。岩石・鉱物試料を、二酸化炭素10%、窒素90%の混合ガスで満たされた反応容器内でゆっくりと粉砕した。容器内に残ったガス組成を逐次ガスクロマトグラフで分析し、反応した二酸化炭素の量を求めた。反応量は、粉砕の速度に応じて増加した。強力に粉砕した場合は、1 時間に1molのカンラン石が0.03molのCO2と反応することがわかった。類似の反応は、自然界で新たに出現した新鮮な岩石の表面でも起こっていよう。たとえば、新しく切り出された石材の表面や、人為的に彫刻された石像の表面では、その切り出された時の大気二酸化炭素との迅速な反応が予想される。もし、そのような岩石表面に、反応時の二酸化炭素が岩石の変質物質として保存されるなら、それは、炭素14年代測定に用いる事が出来ないだろうか?本文はその反応機構を調べた研究の報告である。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"名古屋大学年代測定総合研究センターシンポジウム報告","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.24.168","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 剛","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"83753","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三村, 耕一","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"83754","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Tsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"83755","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mimura, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"83756","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-21"}],"displaytype":"detail","filename":"sumrua_24_168.pdf","filesize":[{"value":"16.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sumrua_24_168.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/18152/files/sumrua_24_168.pdf"},"version_id":"20eeb905-d9ff-4eba-be6d-e8ac34e64a9f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"14C dating","subitem_subject_scheme":"Other"},{"subitem_subject":"silicate rock","subitem_subject_scheme":"Other"},{"subitem_subject":"CO2 adsorption","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanochemical reaction","subitem_subject_scheme":"Other"},{"subitem_subject":"14C年代測定","subitem_subject_scheme":"Other"},{"subitem_subject":"ケイ酸塩岩","subitem_subject_scheme":"Other"},{"subitem_subject":"CO2吸収","subitem_subject_scheme":"Other"},{"subitem_subject":"粉砕反応","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":"ケイ酸塩岩も14C年代測定の対象となるか? : 岩石の粉砕反応によるC02の迅速吸収","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ケイ酸塩岩も14C年代測定の対象となるか? : 岩石の粉砕反応によるC02の迅速吸収","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1612"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-06-10"},"publish_date":"2014-06-10","publish_status":"0","recid":"18152","relation_version_is_last":true,"title":["ケイ酸塩岩も14C年代測定の対象となるか? : 岩石の粉砕反応によるC02の迅速吸収"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:06:41.069690+00:00"}
