In this study, we confirm whether the preferential flattening of poleward-facing slopes was formed during the Amazonian, based on statistical investigation of impact craters on the relatively new surface of the Alba Patera region. In most cases, the angle of the poleward-facing wall is lower than that of the equatorward-facing wall of each crater at latitudes from 35 deg N to over 50 deg N. Shallow craters have both poleward-facing walls, the surface of which seems to be covered with ice-rich material, and floors which tend slightly to incline toward poleward. This may suggest that repeated formation and downward deformation of ice-rich mantling on poleward-facing walls, which is interpreted to have been formed at high obliquity, result in the formation of thick ice-rich infilling. Poleward-facing slopes may be preferentially flattened by the ice-rich deposits rather than erosional modification.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063723022","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学 大学院理学系研究科"},{"subitem_text_value":"東京大学 大学院理学系研究科"},{"subitem_text_value":"長岡技術科学大学 工学部　機械系"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Nagaoka University of Technology Department of Mechanical Engineering, Faculty of Engineering"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 徹之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田近, 英一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"東, 信彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Tetsuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tajika, Eiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Azuma, Nobuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"宇宙探査","subitem_subject_scheme":"Other"},{"subitem_subject":"火星クレータ","subitem_subject_scheme":"Other"},{"subitem_subject":"火星","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星地質学","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星表面","subitem_subject_scheme":"Other"},{"subitem_subject":"平面化","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星気象学","subitem_subject_scheme":"Other"},{"subitem_subject":"レーザー高度計","subitem_subject_scheme":"Other"},{"subitem_subject":"space exploration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mars crater","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mars","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary geology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary surface","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flattening","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary meteorology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laser altimeter","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Preferential flattening of the poleward-facing walls of impact craters in the middle latitudes of Mars","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preferential flattening of the poleward-facing walls of impact craters in the middle latitudes of Mars","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1789","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20442","relation_version_is_last":true,"title":["Preferential flattening of the poleward-facing walls of impact craters in the middle latitudes of Mars"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:50:11.506296+00:00"}
