The thermal gradient was found to be 0.94×1O-2℃/m and 1.21×10-2℃/m in the north and the south parts of the mine respectively. Thermal conductivity of 36 rock specimens collected from various parts of the mine was measured using the divided-bar method. Apparent thermal conductivities of the rocks at the two parts are 6.73～7.08×10-3 cal/cm sec℃ and 6.50～7.43×10-3 cal/cm sec℃. The terrestrial heat flow from the interior to the surface of the earth was computed to be 0.63～0.67×10-6 cal/cm2 sec for the north part and 0.78～0.90×10-6 cal/cm2 sec for the south part. These values are a little smaller than those already found in Japan.","subitem_description_type":"Abstract"},{"subitem_description":"茨城県日立市日立鉱山に於ける地下温度勾配及び岩石熱伝導率測定の結果,鉱山の北部及び南部の二地域で温度勾配はそれそれ0.94℃/100m,1.21℃/100mであること及び等温面がほぼ地表面に平行すなわち熱流の方向がほぼ地表面に垂直であることを見出した.又岩石熱伝導率測定値にもとづいて北部及び南部二地域の見かけの熱伝導率は6.73～7.08×10-3cal/cm sec℃及び6.51～7.43×10-3cal/cm sec℃であると算定された.これによると,地殻内熱流量は北部に於て0.63～0.67×10-6cal/cm2 sec,南部に於て0.79～0.90×10-6cal/cm2 secとなるが,この値は第一報に報告された笹子トンネルに於ける結果2.06×10-6cal/cm2 secよりも低いのみならず世界の平均とされている1.20×10-6cal/cm2 secよりもなお低いようである.ここに求められた結果が,地殻内の局地的異常を表わすものか,或いは更に大規模な現象,中間層に於ける熱対流など,に関連あるものであるかどうかを追求するためには,更にこの程の研究の成果の集積をまたねばならない.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"132125","nameIdentifierScheme":"WEKO"}],"names":[{"name":"宝来, 帰一"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033871","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","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":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute,University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院"},{"subitem_text_value":"地球物理学専門課程"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Horai, Ki'iti"}],"nameIdentifiers":[{"nameIdentifier":"132124","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":"2017-06-27"}],"displaytype":"detail","filename":"ji0374002.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0374002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33871/files/ji0374002.pdf"},"version_id":"5e210897-7451-42ed-bf13-f1330b7df6f8"}]},"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":"Studies of the Thermal State of the Earth.
