The age of the trap was determined by ^\u003c40\u003eAr/^\u003c39\u003eAr dating as 125 to 130 Ma (H. SAKAI et al., J. Geol. Soc. Jpn., 103,192,1997). The VGP (vitual geomagnetic pole) of the Rajmahal trap was studied and compared with the APWP (apparent polar wander path) of India (J. E. BESSE and V. COURTILLOT, J. Geophys, Res., 96,4029,1991). The VGP is situated slightly apart from the position of 120 Ma in Indian APWP, which suggests that the Rajmahal trap is older than 120 Ma. That is, paleomagnetic study supports the ^\u003c40\u003eAr/^\u003c39\u003eAr age of 125-130 Ma. This result suggests that the Rajmahal trap was formed around the age of rifting of India from Antarctica. Thelliers\u0027 paleointensity experiment was applied to the Rajmahal basalt and the paleointensity of 31.4±5.8 μT was determined. The geomagnetic dipole moment in Mesozoic was summarized using formerly reported paleointensities and data in this study. We can identify that the dipole moment from 180 Ma to 125 Ma before the period of Cretaceous quiet zone, oscillates between 30% and 70% of the present moment.", "subitem_description_type": "Other"}]}, "item_1_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15094/00002844", "subitem_identifier_reg_type": "JaLC"}]}, "item_1_publisher_22": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "National Institute of Polar Research"}]}, "item_1_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA1072335X", "subitem_source_identifier_type": "NCID"}]}, "item_1_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Department of Earth Sciences, Toyama University"}, {"subitem_text_language": "en", "subitem_text_value": "National Institute of Polar Research"}, {"subitem_text_language": "en", "subitem_text_value": "Department of Earth Sciences, Toyama University"}, {"subitem_text_language": "en", "subitem_text_value": "Geological Survey of India"}, {"subitem_text_language": "en", "subitem_text_value": "Kanto Gakuen University"}, {"subitem_text_language": "en", "subitem_text_value": "Graduate School of Social and Cultural Studies, Kyushu University"}, {"subitem_text_language": "en", "subitem_text_value": "Department of Earth Sciences, Toyama University"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "1997-09-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00002368117.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "KJ00002368117", "url": "https://nipr.repo.nii.ac.jp/record/2844/files/KJ00002368117.pdf"}, "version_id": "c83273b5-49fc-4878-82d8-50ec71960b1c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Rajmahal trap", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "VGP", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "APWP of India", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "paleointensity", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cretaceous quiet zone", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "PALEOMAGNETIC STUDY OF RAJMAHAL TRAP IN INDIA : DISCUSSION OF GEOMAGNETIC DIPOLE MOMENT AND RECONSTRUCTION OF GONDWANALAND", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "PALEOMAGNETIC STUDY OF RAJMAHAL TRAP IN INDIA : DISCUSSION OF GEOMAGNETIC DIPOLE MOMENT AND RECONSTRUCTION OF GONDWANALAND"}]}, "item_type_id": "1", "owner": "4", "path": ["424"], "permalink_uri": "https://doi.org/10.15094/00002844", "pubdate": {"attribute_name": "公開日", "attribute_value": "1997-09-01"}, "publish_date": "1997-09-01", "publish_status": "0", "recid": "2844", "relation": {}, "relation_version_is_last": true, "title": ["PALEOMAGNETIC STUDY OF RAJMAHAL TRAP IN INDIA : DISCUSSION OF GEOMAGNETIC DIPOLE MOMENT AND RECONSTRUCTION OF GONDWANALAND"], "weko_shared_id": 4}
