A potassium feldspar-stained thin section of granodiorite was used to evaluate the suitability of this method. The modal amount of stained potassium feldspar is 35.7%, measured by point counting on a color photomicrograph of granodiorite with a 32 x 32 grid of points. X-ray element-concentration maps of an area covering the same 32 x 32 grid of points are obtained from a micro-XRF apparatus. A grayscale image is generated by the subtraction of a concentration map of Fe from a concentration map of K. The modal amount of bright areas (K-rich and Fe-poor) is 36.0%, measured by point counting on the grayscale image. The results indicate that the proportion of potassium feldspar is recognizable by micro-XRF element-concentration mapping. A 32 x 32 grid of points is set on a color photomicrograph of sandstone. X-ray element-concentration maps and a grayscale image are obtained by the same process as mentioned above. The modal amount of bright areas, indicating potassium feldspar, is 6.0%, measured by point counting on the grayscale image. There is no need of chemical treatment, mirror-finishing, and conductive coating on rock thin sections for micro-XRF element-concentration mapping. Thus, this technique is practically useful for modal analysis of granitic rocks and sandstone by point counting.","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":"伊地知, 佑太","creatorNameLang":"ja"},{"creatorName":"IJICHI, Yuta","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"山本, 啓司","creatorNameLang":"ja"},{"creatorName":"YAMAMOTO, Hiroshi","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":"2023-01-05"}],"displaytype":"detail","filename":"AA11246904_v55_p8-15.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11246904_v55_p8-15","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/16284/files/AA11246904_v55_p8-15.pdf"},"version_id":"a8d74bf5-b7b3-4fd1-828b-07c24343930d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"potassium feldspar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"point counting","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"granodiorite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sandstone","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":"岩石薄片のマイクロ蛍光X線マッピングによるカリ長石の判別","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"岩石薄片のマイクロ蛍光X線マッピングによるカリ長石の判別","subitem_title_language":"ja"},{"subitem_title":"Identification of potassium feldspar in rock thin sections by micro-XRF mapping","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["53","6063"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-01-05"},"publish_date":"2023-01-05","publish_status":"0","recid":"16284","relation_version_is_last":true,"title":["岩石薄片のマイクロ蛍光X線マッピングによるカリ長石の判別"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-08T04:50:16.111944+00:00"}
