Thus, researchers often add quantitative information on grain size, mineralogical composition, and chronology. In this context, a mathematical approach published in 2013 distinguished the shape of quartz sand sampled from the three depositional landforms: beach, riverbank, and glacier foreland. In this study, we applied the same method to basal till, ice-marginal till and a deep-seated landslide (rock avalanche) deposit. The results indicated the difficulty of discrimination between glacial till and rock avalanche deposit using this method. The first, second and third principal components of the elliptic Fourier analysis of the all quartz samples were distributed within the same range. The fractal dimensions, each of which represents the roughness of a sand surface, did not indicate any difference between the basal till and ice-marginal till or between the till and rock avalanche deposit. On the other hand, the fractal dimensions were different between samples of different lithology. Abrasion on sand particles through the transportation by alpine glaciers or rock avalanche is probably not strong enough to modify the original shapes of quartz. In our study area, the higher proportion of mud in the basal till, which was measured by wet sieving, seems to be a helpful indicator to distinguish glacial sediments from rock avalanche deposits.", "subitem_description_type": "Abstract"}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15068/00154209", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "University of Tsukuba, Doctoral Program in Geoenvironmental Sciences, Graduate School of Life and Environmental Sciences"}]}, "item_4_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_4_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1880-6252", "subitem_source_identifier_type": "ISSN"}]}, "item_4_source_id_9": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12119094", "subitem_source_identifier_type": "NCID"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u6c60\u7530, \u6566"}, {"creatorName": "\u30a4\u30b1\u30c0, \u30a2\u30c4\u30b7", "creatorNameLang": "ja-Kana"}, {"creatorName": "IKEDA, Atsushi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "203935", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "60431657", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000060431657"}, {"nameIdentifier": "0000001118", "nameIdentifierScheme": "\u7b51\u6ce2\u5927\u5b66\u7814\u7a76\u8005\u7dcf\u89a7", "nameIdentifierURI": "http://trios.tsukuba.ac.jp/researcher/0000001118"}]}, {"creatorNames": [{"creatorName": "FUSE, Tomoaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "205618", "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": "2019-02-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "TGS_14-31.pdf", "filesize": [{"value": "1.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1900000.0, "url": {"label": "TGS_14-31.pdf", "url": "https://tsukuba.repo.nii.ac.jp/record/48737/files/TGS_14-31.pdf"}, "version_id": "c904a5e2-0acc-42ad-90e9-3cdf9b1cb276"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "glacier", "subitem_subject_scheme": "Other"}, {"subitem_subject": "deep-seated landslide", "subitem_subject_scheme": "Other"}, {"subitem_subject": "grain shape", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fractal dimension analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "elliptic Fourier analysis", "subitem_subject_scheme": "Other"}]}, "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": "\u3008Research Reports\u3009Shape of sand particles transported by glaciers or through rock avalanches: A preliminary trial for discriminating the origin of coarse deposits", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u3008Research Reports\u3009Shape of sand particles transported by glaciers or through rock avalanches: A preliminary trial for discriminating the origin of coarse deposits"}]}, "item_type_id": "4", "owner": "1", "path": ["160/7647", "3/2622/2624/7244"], "permalink_uri": "https://doi.org/10.15068/00154209", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2019-02-08"}, "publish_date": "2019-02-08", "publish_status": "0", "recid": "48737", "relation": {}, "relation_version_is_last": true, "title": ["\u3008Research Reports\u3009Shape of sand particles transported by glaciers or through rock avalanches: A preliminary trial for discriminating the origin of coarse deposits"], "weko_shared_id": 5}
