At the same time, the author examined the magnetic stability of rocks of which the magnetic directions were indicated to be much deflected from the present geomagnetic direction. From the results obtained, it was found that the geomagnetic field may have been reversed during Upper Pliocene time, and that during the time from the Upper Miocene to the Lower Pliocene it was normal. During the transitional stage from the normal to the reversed, the geomagnetic pole seems to have migrated through the equator; thus the change of polarity or the reversal might, through the transitional phase, have taken place with the pole settling at various positions. This conception regarding the manner of reversal of the geomagnetic field differs completely from the hypothesis hitherto propounded. The intensities of total geomagnetic force during this transitional phase were inferred from the ratios of Jn to JTc of the rocks: it was suggested that the geomagnetic intensity decreased through the time of reversal and then began to increase again as the change in the reversal proceeded to its finality.", "subitem_description_type": "Abstract"}, {"subitem_description": "Pliocene\u306b\u304a\u3051\u308b\u5730\u7403\u78c1\u5834\u306e\u5909\u52d5\u3092\u7a76\u660e\u3059\u308b\u76ee\u7684\u3067\u5c0f\u8af8\u5c64\u7fa4,\u67f5(\u3057\u304c\u3089\u307f)\u7d2f\u5c64\u304a\u3088\u3073\u5869\u5dba\u7d2f\u5c64\u306e\u53e4\u5730\u78c1\u6c17\u5b66\u7684\u7814\u7a76\u3092\u884c\u306a\u3064\u305f,\u305d\u306e\u7d50\u679c\u6b21\u306e\u3053\u3068\u304c\u660e\u3089\u304b\u3068\u306a\u3064\u305f.(1)Upper Miocene-Lower Pliocene\u306b\u306f\u5730\u7403\u53cc\u6975\u5b50\u306eS\u6975\u306f\u5317\u6975\u570f\u306b\u3042\u308a,Later Pliocene", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "131660", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u767e\u702c, \u5bdb\u4e00"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000033710", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162258", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00408972", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u5730\u9707\u7814\u7a76\u6240"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Momose, Kan-ichi"}], "nameIdentifiers": [{"nameIdentifier": "131659", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ji0413003.pdf", "filesize": [{"value": "2.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2600000.0, "url": {"label": "ji0413003.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/33710/files/ji0413003.pdf"}, "version_id": "9e97f45d-a7d4-4c00-82df-47d74d4ba5df"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Studies on the Variations of the Earth\u0027s Magnetic Field during Pliocene Time", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Studies on the Variations of the Earth\u0027s Magnetic Field during Pliocene Time", "subitem_title_language": "en"}]}, "item_type_id": "4", "owner": "1", "path": ["80/4535/4967/4971", "9/504/4538/4969/4972"], "permalink_uri": "https://doi.org/10.15083/0000033710", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-03-31"}, "publish_date": "2009-03-31", "publish_status": "0", "recid": "33710", "relation": {}, "relation_version_is_last": true, "title": ["Studies on the Variations of the Earth\u0027s Magnetic Field during Pliocene Time"], "weko_shared_id": -1}
