Possible temperature distribution was calculated on assuming that the upper mantle is mainly composed of eclogite. In the subcontinental upper mantle, actual temperature is believed to be close to the melting point of eclogite between a depth of 120 and 250 km which coincides with the depth of the low velocity zone. The author proposed that the low velocity zone is starred with oblate spheroidal molten pockets. The elastic ratio at normal temperature and pressure, 0oo, has been calculated for the upper mantle, in which the elastic ratio increases from 40(km/s)2 to 50(km/s)2 implying a gradual variation of constituent mineral assemblage with depth. From the considerations of mean atomic weight, density, velocity as well as elastic ratio, the author suggests that the upper mantle is mainly composed of olivine, pyroxene, garnet(pyrope) or even jadeite. Hence, eclogite or garnet peridotite will be the most favourable material in the upper mantle, the basaltic magma being the product of partial melting of these materials originating from the low velocity zone.", "subitem_description_type": "Abstract"}, {"subitem_description": "Upper mantle\u306b\u304a\u3051\u308bPoisson\u6bd4\u306e\u5897\u52a0\u7387\u304b\u3089,eclogite\u306emelting curve\u3092\u3082\u3068\u306b\u3057\u3066\u6e29\u5ea6\u5206\u5e03\u3092\u8a08\u7b97\u3057\u306a\u304a\u3057\u305f.\u03c6\u306b\u5727\u529b\u3068\u6e29\u5ea6\u306e\u88dc\u6b63\u3092\u884c\u3064\u3066,\u5404\u6df1\u3055\u306b\u3064\u3044\u3066\u5e38\u6e29\u5e38\u5727\u306b\u304a\u3051\u308b\u5024\u3092\u8a08\u7b97\u3057,\u7a0b\u3005\u306e\u73ea\u9178\u5869\u304a\u3088\u3073\u9178\u5316\u7269\u306e\u305d\u308c\u3068\u6bd4\u8f03\u3057\u305f.\u73fe\u306b\u7e26\u6ce2\u901f\u5ea6,\u5e73\u5747\u539f\u5b50\u91cf\u306a\u3069\u3092\u8003\u616e\u3057\u3066\u6b21\u306e\u7d50\u8ad6\u3092\u5f97\u305f.1) elogite\u30e2\u30c7\u30eb\u306b\u3088\u308b\u6e29\u5ea6\u306f\u6df1\u3055120-220km\u3067ecloerite\u306e\u878d\u70b9\u306b\u8fd1\u63a5\u3059\u308b.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "131525", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u4e0b\u9db4, \u5927\u8f14"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000033669", "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": "Earthquake Research Institute"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "SHIMOZURU, Daisuke"}], "nameIdentifiers": [{"nameIdentifier": "131524", "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": "ji0423004.pdf", "filesize": [{"value": "662.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 662800.0, "url": {"label": "ji0423004.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/33669/files/ji0423004.pdf"}, "version_id": "aa608425-c2c7-4b6c-84ce-afca3e5f96cf"}]}, "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": "23.
