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", "download_preview_message": "", "file_order": 0, "filename": "KJ00001014953.pdf", "filesize": [{"value": "79.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 79600.0, "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"], "permalink_uri": "https://doi.org/10.15094/00003990", "pubdate": {"attribute_name": "公開日", "attribute_value": "1997-11-01"}, "publish_date": "1997-11-01", "publish_status": "0", "recid": "3990", "relation": {}, "relation_version_is_last": true, "title": ["ICE CRYSTAL ORIENTATION DISTRIBUTIONS IN LARGE ICE MASSES"], "weko_shared_id": 4}
