If a tephra containing minerals which were completely time-zeroed at the time of an eruption, its TL age might be the same as the age obtained by the OSL technique. According to our research, the ages by TL and OSL methods for the same tephra, however, are not necessarily the same. The TL ages and OSL ages were compared for eleven tephras from Tohoku and Kyushu areas. Quartz coarse grains, poly-mineral semi-fine grains, poly-mineral fine grains and quartz fine grains were used for the measurements, which were made using three apparatuses with different detection optical filters and excitation light sources. The compared results of the TL and OSL ages are grouped into four categories;(1) the TL age agrees with the OSL age, (2) the OSL age is younger than the TL age, (3) the TL age obtained using the sample after the OSL measurement is older than the TL and OSL ages and (4) the OSL age indicates the time of the last deposition of the tephra. Some aspects of the differences between the TL and OSL ages are discussed in this paper", "subitem_description_type": "Abstract"}]}, "item_3_full_name_2": {"attribute_name": "著者(ヨミ)", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "37048", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ナガトモ, ツネト"}]}, {"nameIdentifiers": [{"nameIdentifier": "37049", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "シタオカ, ヨリナオ"}]}, {"nameIdentifiers": [{"nameIdentifier": "37050", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ニシムラ, セイジ"}]}]}, "item_3_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "37051", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NAGATOMO, Tsuneto"}]}, {"nameIdentifiers": [{"nameIdentifier": "37052", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SHITAOKA, Yorinao"}]}, {"nameIdentifiers": [{"nameIdentifier": "37053", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NISHIMURA, Seiji"}]}]}, "item_3_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "奈良教育大学"}]}, "item_3_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "05472407", "subitem_source_identifier_type": "ISSN"}]}, "item_3_source_id_9": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00181070", "subitem_source_identifier_type": "NCID"}]}, "item_3_version_type_15": {"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": "長友, 恒人"}], "nameIdentifiers": [{"nameIdentifier": "37045", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "下岡, 順直"}], "nameIdentifiers": [{"nameIdentifier": "37046", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "西村, 誠治"}], "nameIdentifiers": [{"nameIdentifier": "37047", "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": "2017-02-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "54-2-01-2005.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "54-2-01-2005.pdf", "url": "https://nara-edu.repo.nii.ac.jp/record/7762/files/54-2-01-2005.pdf"}, "version_id": "c24bcef9-7bba-4a38-a4f4-1556ae0b1fca"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Tephra", "subitem_subject_scheme": "Other"}, {"subitem_subject": "TL dating", "subitem_subject_scheme": "Other"}, {"subitem_subject": "OSL dating", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cross check", "subitem_subject_scheme": "Other"}, {"subitem_subject": "テフラ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "TL年代測定法", "subitem_subject_scheme": "Other"}, {"subitem_subject": "OSL年代測定法", "subitem_subject_scheme": "Other"}, {"subitem_subject": "クロスチェック", "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": "同一テフラのTL年代とOSL年代の比較", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "同一テフラのTL年代とOSL年代の比較"}]}, "item_type_id": "3", "owner": "4", "path": ["1299"], "permalink_uri": "http://hdl.handle.net/10105/113", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-06-10"}, "publish_date": "2010-06-10", "publish_status": "0", "recid": "7762", "relation": {}, "relation_version_is_last": true, "title": ["同一テフラのTL年代とOSL年代の比較"], "weko_shared_id": -1}
