There are three processes involved in fabric formation; i.e. crystal rotation (AZUMA and HIGASHI, 1985), recrystalization and polygonization. Two types of crystal fabric development with depth have been observed in deep polar ice cores. Type A shows crystal fabric changes from a random distribution near the surface to vertical cluster development with depth under vertical compression and to a strong single maximum pattern near the bottom under simple shear deformation (Camp Century, Dye 3,GRIP and Byrd ice cores). Type B shows fabric changes from a random distribution near the surface to a large girdle development with depth, where the c-axis direction is almost perpendicular to the uniaxial tensile strain axis along the ice flow direction (Mizuho and Vostok ice cores). To estimate vertical compressive strain, ε and uniaxial tensile strain, γ, the following equations were assumed : ε=-ln(y/H), γ=-2ln(y/H), where y is height from the bottom and H is ice thickness. For Type A cores, the c-axis lies mainly along the vertical core direction with depth and a single maximum fabric appears at depth for about ε=150%, except for Byrd core samples which shows single maximum fabric appearance for about ε=80%. For Type B cores, crystal fabrics developments with an increase in γ are quite similar to each other.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003990","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":"AA10756213","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 Civil Engineering, Kitami Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-11-01"}],"displaytype":"detail","filename":"KJ00001014953.pdf","filesize":[{"value":"79.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00001014953","url":"https://nipr.repo.nii.ac.jp/record/3990/files/KJ00001014953.pdf"},"version_id":"f3b29c30-e04f-4f3d-a45c-d64f6c021d3b"}]},"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":"ICE CRYSTAL ORIENTATION DISTRIBUTIONS IN LARGE ICE MASSES","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ICE CRYSTAL ORIENTATION DISTRIBUTIONS IN LARGE ICE MASSES"}]},"item_type_id":"1","owner":"4","path":["535"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-11-01"},"publish_date":"1997-11-01","publish_status":"0","recid":"3990","relation_version_is_last":true,"title":["ICE CRYSTAL ORIENTATION DISTRIBUTIONS IN LARGE ICE MASSES"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:25:31.048589+00:00"}
